AXIS 207/207W - Video Streams 13 Video Streams The AXIS 207/AXIS 207W provides several different image and video stream formats. The type to use depends on your requirements and on the properties of your network. The Live View page in the AXIS 207/AXIS 207W provides access to MPEG-4 and Motion JPEG video streams, as well as to single JPEG images. Other applications and clients can also access these video streams/images directly, without going via the Live View page. How to stream MPEG-4 This video compression standard makes good use of bandwidth, and can provide high-quality video streams at less than 1 Mbit/s. Note that the image settings of the MPEG-4 stream are the same for all clients. Deciding on the combination of protocols and methods to use depends on your viewing requirements, and on the properties of your network. The available options in AMC are: Unicast RTP This unicast method (RTP over UDP) should be your first consideration for live unicast video, especially when it is important to always have an up-to-date video stream, even if some images are dropped. This unicast method (RTP tunneled over RTSP) is useful as it is relatively simple to configure firewalls to allow RTSP traffic. This unicast method can be used to traverse firewalls. Firewalls are commonly configured to allow the HTTP protocol, thus allowing RTP to be tunneled. RTP over RTSP Unicasting is used for video-on-demand broadcasting, so that there is no video traffic on the network until a client connects and requests the stream. Note: There is a maximum of 10 simultaneous unicast connections. RTP over RTSP over HTTP Multicast RTP This method (RTP over TCP) should be used for live multicast video. The video stream is always up-to-date, even if some images are dropped. Multicasting provides the most efficient usage of bandwidth when there are large numbers of clients viewing simultaneously. A multicast broadcast cannot however, pass a network router unless the router is configured to allow this. It is thus not possible to multicast over e.g. the Internet. Note also that all multicast viewers count as one unicast viewer in the maximum total of 10 simultaneous connnections. AMC will negotiate with the camera to determine exactly which transport protocol to use in the order listed above. This order can be changed and the options disabled, to suit any specific requirements. Important! MPEG-4 is licensed technology. The AXIS 207/AXIS 207W includes one viewing client license. Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis reseller. 14 AXIS 207/207W - Video Streams MPEG-4 clients AXIS Media Control (AMC) The recommended method of accessing live video (MPEG-4 and Motion JPEG) from the AXIS 207/AXIS 207W is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer in Windows. The AMC control panel can be used to configure various video and audio settings. Please see the readme file included in the tool for more information. The AMC control panel is automatically installed on first use, after which it can be configured. Open the AMC Control Panel from: · Windows Control Panel (from the Start menu) · Alternatively, right-click the video image in Internet Explorer and click Settings in the menu. QuickTimeTM & Real PlayerTM To access the video stream from e.g. QuickTimeTM or Real PlayerTM the following paths can be used: · rtsp:///mpeg4/media.amp · rtsp:///mpeg4/media.3gp Notes: · The AXIS 207/207W supports QuickTime 6.5.1 (or later) and Real Player 10.5 (or later) · QuickTime adds latency to the video and audio stream (up to 3 seconds) · It may be possible to use other players to view the MPEG-4 stream using the paths above, although this is not guaranteed by Axis · = IP address Motion JPEG This format uses standard JPEG still images for the video stream. These images are then displayed and updated at a rate sufficient to create a stream that shows constantly updated motion. The Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image quality and access to each and every individual image contained in the stream. The recommended method of accessing Motion JPEG live video from the AXIS 207/207W is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer in Windows. AXIS 207/207W - Video Streams Note also that multiple clients accessing Motion JPEG streams can use different image settings. Alternative methods of accessing the video stream Video/images from the AXIS 207/207W can also be accessed in the following ways: · The AXIS 207/207W is 3GPP compatible - enter the path: · rtsp:///mpeg4/media.3gp Refer to 3GPP Compatibility, on page 10 for more information. · Motion JPEG server push (if supported by the client, e.g. Mozilla/Firefox). This option maintains an open HTTP connection to the browser and sends data as and when required, for as long as required. See HTML Examples, on page 23. · Still JPEG images in a browser. Enter e.g. the path: http:///axis-cgi/jpg/image.cgi?resolution=320x240 · Windows Media Player. This requires AMC and the MPEG-4 viewing client to be installed. The paths that can be used are listed below in the order of preference. · Unicast via RTP: axrtpu:///mpeg4/media.amp · Unicast via RTSP: axrtsp:///mpeg4/media.amp · Unicast via RTSP, tunneled via HTTP: axrtsphttp:///mpeg4/media.amp · Multicast: axrtpm:///mpeg4/media.amp Note: = IP address 15 16 AXIS 207/207W - Configuration Configuration This section describes how to configure the camera, and is intended for product Administrators, who have unrestricted access to all the Setup tools, and Operators, who have access to the settings for Video & Image, Audio, Live View Config and Event Configuration. The camera is configured from Setup, from a standard browser (see Supported Web Browsers, on page 44). The descriptions below show examples of the features available in the AXIS 207/207W. For details of each setting, please refer to the online help available from the setup tools. Click to access the online help. Accessing the Setup tools Follow the instructions below to access the Setup tools from a browser. 1. Start your browser and enter the IP address or host name of the camera in the location/address field. 2. The Live View page is now displayed. Click Setup to display the Setup tools. Setup tools AXIS Media Control The AXIS Media Control (AMC) is installed automatically the first time the camera is accessed from Microsoft Internet Explorer. The AMC control panel can be opened by right-clicking on the video image in the Live View web page. The AMC control panel can be used to configure various video and audio settings. Please see the readme file included in the tool for more information. AXIS 207/207W - Configuration 17 Video and Image settings Image Appearance Use these settings to change the image as required. The video image can be rotated and fine-tuned by adjusting the color level, the brightness and the sharpness. The configuration of the video image will affect the camera's overall performance, depending on how it is used and on the available bandwidth. Setting higher resolution and lower compression improves video image quality, but increases the amount of bandwidth used. Please see the online help for further information on these settings. Overlay Settings Use these settings to include a text, date and time overlay. The text, date and time overlay is included on one line at the top or bottom of the video image. Text, date and time overlay 18 AXIS 207/207W - Configuration Video Stream Define the maximum video stream time per session in seconds, minutes or hours, or set it as unlimited. When the set time has expired, a new stream can be started by refreshing the page in the browser. Note that the maximum video stream time does not apply to clients connecting via multicast. The frame rate allowed to each viewer can also be limited, to avoid bandwidth problems on the network. Test For a preview of the image before saving, click Test. When satisfied with the settings, click Save. Please note that the preview image will be in JPEG format, even though the settings are valid both for Motion JPEG and MPEG-4. Please refer to the online help for more information Advanced - Camera Settings These pages include different settings for fine-tuning the video image. To compensate for the lighting conditions, the white balance and exposure control can be adjusted. Please see the online help for further instructions on these settings. Low Light Behavior Exposure priority defines the balance between image quality and the frame rate. Higher image quality may reduce frame rate and increase motion blur. A prioritized frame rate may instead increase the image noise. Depending on requirements, use this to give higher priority to the image quality or to the frame rate. . AXIS 207/207W - Configuration Advanced - MPEG-4 Settings GOV Settings The GOV structure describes the composition of the MPEG-4 video stream. Setting the GOV-length to a high value saves considerably on bandwidth. The Cyclic refresh parameter gives a smoother bit rate and can be useful if bandwidth is limited. Note: Cyclic refresh should not be enabled if Event handling is enabled and the file format is set to MPEG-4 under Upload images/video (under Setup > Event configuration > Event settings). 19 Bit Rate Control Limiting the maximum bit rate is a good way of controlling the bandwidth used by the MPEG-4 video stream. Leaving the Maximum bit rate as unlimited will provide consistently good image quality, but at the expense of increased bandwith usage whenever there is more activity in the image. Limiting the bit rate to a defined value will prevent excessive bandwidth usage, but images will be lost when the limit is exceeded. Note that a maximum bit rate can be used for both variable and constant bit rates. The bit rate type can be set as Variable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR will adjust the bit rate according to the images' complexity, thus using a lot of bandwidth for a lot of activity in the image and less for lower activity in the monitored area. Audio Settings General The AXIS 207/207W has a built-in microphone for one way MPEG-4, ISMA, 3GPP compatible audio. Enable audio - click the checkbox to enable Audio (disabled by default). Note: To receive synchronized video and sound, it is recommended that the camera time is synchronized with an NTP Server. This is enabled under System Options > Date & Time. Please refer to the help pages for more information. 20 AXIS 207/207W - Live View Config Live View Config Layout These are the tools for deciding the layout of the Live View page.

The event is the set of parameters (or conditions) that specifies how and when which actions will be performed. A common event is when the camera uploads images, triggered by an alarm. This section describes how to configure the AXIS 207/207W to perform certain actions when an event (e.g. an alarm) occurs. Triggered by... Input Port This describes the state that the input must be in for an event to be triggered e.g. a door sensor connected to the camera's input port. If the door sensor is active, an event is triggered. Motion Detection Movement in a motion detection window can be used to trigger an event. Select the motion detection window from the drop-down list and specify whether to trigger the event when motion stops or starts. For information on how to set up motion detection windows see Motion Detection, on page 26. Manual Trigger This option makes use of the action buttons on the live view page, which are used to start or stop the event manually, e.g. activate an alarm connected to the camera's output port. Alternatively the event can be triggered via the product's API (Application Programming Interface). When Triggered... Upload images/video - this option sends the saved images in email messages to specified email addresses. Enter the file format (MPEG-4 or JPEG), email address, subject and additional information for the email message. Multiple email addresses can be entered. Check the Include audio checkbox if audio is to be included in the email (MPEG-4 only). Note: Mail servers must be configured under System Options > Network > SMTP AXIS 207/207W - Event Configuration Pre-trigger and Post-trigger buffers - This function is useful when checking to see what happened immediately before and/or after a trigger, e.g. 30 seconds before and/or after a door was opened. Include pre-trigger buffer - images stored internally in the camera from the time immediately preceding the trigger. Check the box to enable the pre-trigger buffer and enter the desired length of time (and the required image frequency if JPEG is selected). Include post-trigger buffer - contains images from the time immediately after the trigger. Configure as for pre-trigger. Notes: ·Pre-trigger and Post-trigger buffers will be lost if the connection to the mail server fails. ·Cyclic refresh must be disabled if Event handling is enabled and the file format is set to MPEG-4 See Setup > Video & Image > Advanced > MPEG-4. ·The maximum length of the pre-/post-buffer depends on the video image size (and frame rate). 25 Base file name - this name will be used for all of the image files saved. If suffixes are also used, the file name will take the form . Add a sequence number suffix - keep track of uploaded images by assigning each image with a number. Use own file name format - check this radio button to use a customized file name. Enter the file name in the Base file name field above.

It is not possible to use both interfaces simultaneously. IP Address Configuration In the AXIS 207W these settings are grouped according to the network interface. The camera's IP address can be set automatically via DHCP, or a fixed IP address can be set manually. A host name can be used and there are options for setting up notification of changes in the IP address. DHCP is enabled by default. Notes: · DHCP is a protocol for automatic IP address assignment on a network. IP address assignment via DHCP may lead to the situation where the IP address changes and you lose contact. Configure the options for notification of IP address change (under Services) to receive notification from the camera when the IP address changes. · Alternatively, if your DHCP server can update a DNS server, you can access the AXIS 207/207W by host name which is always the same, regardless of the IP address. Services Options for notification of IP address change - if the IP address for the camera changes, e.g. automatically by DHCP, you can choose to be notified of the change. Click Settings... and enter the required information. AXIS Internet Dynamic DNS Service - use the AXIS Internet Dynamic DNS service to assign a host name for easy access to your AXIS 207 Network Camera. Click Settings... to register your AXIS 207 with the Axis Internet Dynamic DNS service, or to modify the existing settings. The domain name currently registered at the Axis Internet Dynamic DNS service for your product can at any time be removed. For more information, please refer to the online help. Network - Advanced TCP/IP Settings DNS Configuration DNS (Domain Name Service) provides the translation of host names to IP addresses on your network. 30 AXIS 207/207W - System Options Obtain DNS server address via DHCP - automatically use the DNS server settings provided by the DHCP server. Click the View button to see the current settings. Use the following DNS server address - enter the desired DNS server by specifying the following: Domain name - enter the domain(s) to search for the host name used by the AXIS 207.

The host name is always the first part of a Fully Qualified Domain Name, e.g. myserver is the host name in the Fully Qualified Domain Name myserver.mycompany.com where mycompany.com is the Domain name. DNS servers - enter the IP addresses of the primary and secondary DNS servers. NTP Configuration Obtain NTP server address via DHCP - check this radio button to automatically look up and use the NTP server settings as provided by DHCP. Click the View button to see the current settings. Use the following NTP server address - to make manual settings, check this radio button and enter the host name or IP address of the NTP server. Host Name Configuration The AXIS 207/207W can be accessed using a host name, instead of an IP address. The host name is usually the same as the assigned DNS Name. For more information, please see the online help. Link-Local Address This is enabled by default and assigns the AXIS 207 an additional IP address for use with UPnPTM. The AXIS 207 can have both a Link-Local IP and a static/DHCP-supplied IP address at the same time - these will not affect each other. HTTP The default HTTP port number (80) can be changed to any port within the range 1024-65535. This is useful for e.g. simple security port mapping. NAT traversal (port mapping) A broadband router allows devices on a private network (LAN) to share a single connection to the Internet. This is done by forwarding network traffic from the private network to the "outside" i.e. the Internet. Security on the private network (LAN) is increased since most broadband routers are pre-configured to stop any attempts to access the private network (LAN) from the public network/Internet. AXIS 207/207W - System Options Use NAT traversal when your AXIS 207/207W is located on an intranet (LAN) and you wish to make it available from the other (WAN) side of a NAT router. With NAT traversal properly configured, all HTTP traffic to an external HTTP port in the NAT router will be forwarded to the camera. LAN (intranet) Broadband (NAT) router 31 WAN (internet) ISP Notes: · For NAT traversal to work, this must also be supported by the broadband router. · The broadband router has many different names: "NAT router", "Network router", Internet Gateway", "Broadband sharing device" or "Home firewall" but the essential purpose of the device is the same. Enable/Disable - When enabled, the AXIS 207/207W will attempt to configure port mapping in a NAT router on your network, using UPnPTM. Note that UPnPTM must be enabled in the camera (see System Options > Network > UPnP). AXIS Internet Dynamic DNS Service - Use this free service to assign a host name (user-friendly name) for easy access to your camera. If the IP address of the camera or NAT router changes, the AXIS Internet Dynamic DNS Service will automatically be updated with the new IP address. Use manually selected NAT router - Select this option to manually select a NAT router and enter the IP address for the router in the field provided. If a router is not manually specified, the AXIS 207/207W will automatically search for NAT routers on your network. If more than one router is found, the default router will be selected. Alternative HTTP port - Select this option to manually define an external HTTP port. Enter the port number in the field provided. If no port is entered here a port number will automatically be selected when NAT traversal is enabled. Notes: · An alternative HTTP port can be used/be active even if NAT traversal is disabled. This is useful if e.g. your NAT router does not support UPnP and you need to manually configure port forwarding in the NAT router. · If a manually selected port is already in use, another will automatically be selected. · When the port is selected automatically it will be displayed in this field. This can be changed by entering a new port number and clicking Save. 32 AXIS 207/207W - System Options RTSP The RTSP protocol allows a connecting client to start an MPEG-4 stream. Enter the RTSP port number to use. The default setting is 554. Network Traffic Connection Type - The default setting is Auto-negotiate, which means that the correct speed is automatically selected. If necessary, you can set the connection speed by selecting it from the drop-down list. For more information, please see the online help. Wireless (AXIS 207W only) These settings should always be made in the camera first and secondly in the wireless access point. This ensures that the camera is always accessible when making changes. Using a wired connection ensures greater secrecy while making these settings. Status of Wireless Networks This list is the result of a network scan. Access points with a disabled SSID Broadcast will not appear unless the camera is associated with it. The network currently associated to is shown in blue. A network using unsupported security is shown in grey. The following information is provided: · SSID - The name of a wireless network (or ad-hoc device). If the same name occurs several times this means that several access points for that network were found. The AXIS 207W cannot be configured to only associate with one particular access point. · Mode - The Access Point (Master) or Ad-Hoc device. · Security - Shows which type of security the network uses. See below for the security types supported by the AXIS 207W. · Channel - Shows the wireless channel currently in use. · Signal strength - Shows the signal strength. · Bit rate - Shows the bit rate in Mbit/s. This can only be shown for the access point currently in use. Note that the bit rate shown is the current rate, and that this value may vary over time. Wireless Settings These settings control how the AXIS 207W interacts with the wireless network. Apart from identifying the wireless network, it is also possible to enable wireless encryption. SSID - This is the name of the wireless network the AXIS 207W is configured for. The field accepts up to 32 alphanumeric characters. The name must be exactly the same as that used in the wireless access point, or the connection will not be established. AXIS 207/207W - System Options Leaving this field blank means the AXIS 207W will attempt to access the nearest open network. Note: SSID is sometimes written as ESSID. Security - The AXIS 207W supports two security methods: · WPA-PSK (recommended method) · WEP WPA-PSK (Wi-Fi Protected Access - Pre-Shared Key) The AXIS 207W uses a pre-shared key (PSK) for key management. The pre-shared key can be entered either as Manual hex, as 64 hexadecimal (0-9, A-F) characters, or as a Passphrase, using 8 to 63 ASCII characters. WEP (Wired Equivalent Protection) WEP - Authentication - Select Open or Shared Key System Authentication, depending on the method used by your access point. Not all access points have this option, in which case they probably use Open System, which is sometimes known as SSID Authentication. WEP - Key length - This sets the length of the key used for the wireless encryption, 64 or 128 bit. The encryption key length can sometimes be shown as 40/64 and 104/128. WEP - Key Type - The key types available depend on the access point being used. The following options are available: · Manual - Allows you to manually enter the hex key. · ASCII - In this method the string must be exactly 5 characters for 64-bit WEP and 13 characters for 128-bit WEP. · Passphrase - The passphrase can contain up to 31 characters. In 64-bit WEP, the Passphrase generates 4 different keys. For 128-bit WEP, only 1 key is generated, which is then replicated for all 4 keys. Key generation is not standardized and can differ from brand to brand. Check that the generated keys are identical to those in your access point - if not, they must be entered manually. WEP - Active Transmit Key - When using WEP encryption, this selects which of the 4 keys the AXIS 207W uses when transmitting. 33 SMTP (email) Enter the host names or addresses for your primary and secondary mail servers in the fields provided, to enable the sending of notifications and image/video email messages from the camera to predefined addresses via SMTP. If your mail server requires authentication, check the box for Use authentication to log in to this server and enter the necessary information. 34 AXIS 207/207W - System Options UPnPTM The camera includes support for UPnPTM, which is enabled by default.

If the pushbutton is pressed, the state changes and the input becomes active (shown under Event Configuration > Port Status). · Output - connects e.g. an alarm device that can be activated by Output buttons on the Live View page, or by an Event Type. The output will show as active (Event Configuration > Port Status) if the alarm device is activated. Function Transistor Output Pin 4 Description With a maximum load of 100mA and a maximum voltage of 24V DC, this output has an open-collector NPN transistor with the emitter connected to the GND pin. If used with an external relay, a diode must be connected in parallel with the load, for protection against voltage transients. Connect to GND to activate, or leave floating (or unconnected) to deactivate. Pinouts The I/O terminal pins on the AXIS 207 and AXIS 207W are numbered as shown below.

One of your first actions when troubleshooting a problem should be to check the currently installed firmware version. The latest version may contain a correction that fixes your particular problem. The current firmware version in your camera can be seen on the page Setup > Basic Configuration. Upgrading the Firmware When you upgrade the firmware with a file from the Axis Web site, your camera will receive the latest available functionality. Always read the upgrade instructions and release notes available with each new release, before updating the firmware. Note: Preconfigured and customized settings will be saved when the firmware is upgraded (providing the features are available in the new firmware) although this is not guaranteed by Axis Communications. Always read the instructions and release notes available with each new release, before upgrading the firmware. 1. Save the firmware file to your computer. The latest version of the firmware is available free of charge from the Axis Web site at www.axis.com/techsup 2. Go to Setup > System Options > Maintenance in the camera's Web pages. 3. In the Upgrade Server section, browse to the desired firmware file on your computer. Click Upgrade. Notes: ·After starting the upgrade process, always wait at least 10-15 minutes before restarting the camera, even if you suspect the upgrade has failed. ·Your dealer reserves the right to charge for any repair attributable to faulty upgrading by the user. 40 AXIS 207/207W - Troubleshooting Emergency Recovery Procedure If power or the network connection to the camera is lost during the upgrade, the process will fail and the unit will become unresponsive. A flashing red Status LED indicates a failed upgrade. To recover the unit, follow the steps below. The serial number is found on the label attached to the bottom of the camera. 1. Unix/Linux - From the command line, type the following: arp -s temp ping -s 408 Windows - From a command/DOS prompt, type the following: arp -s ping -l 408 -t 2. If the unit does not reply within a few seconds, restart it and wait for a reply. Press CTRL+C to stop Ping. 3. Open a browser and type in the camera's IP address. In the page that appears, use the Browse button to select the upgrade file to use, e.g. axis207.bin. Then click the Load button to restart the upgrade process. 4. After the upgrade has completed (1-10 minutes), the unit will automatically restart and show a steady green on the Power and Status LEDs and flashing green or amber on the Network LED. 5. Referring to the installation guide, reinstall the camera. If the emergency recovery procedure does not get the camera up and running again, please contact Axis support at www.axis.com/techsup/ Axis Support If you contact Axis support, please help us to help you solve your problems, by providing the server report, the log file and a brief description of the problem. Server Report - go to Setup > System Options > Support Overview. The server report contains important information about the server and its software, as well as a list of the current parameters. The Log file is available from Setup > System Options > Logs & Reports. The Log file records events in the unit since the last system restart and can be a useful diagnostic tool when troubleshooting. AXIS 207/207W - Troubleshooting Symptoms, Possible Causes and Remedial Actions Problems setting the IP address When using ARP/Ping Try the installation again. The IP address must be set within two minutes after power has been applied to the camera. Ensure the Ping length is set to 408. See the Installation Guide. If the IP address intended for the camera and the IP address of your computer are located on different subnets, you will not be able to set the IP address. Contact your network administrator to obtain an appropriate IP address. Disconnect the camera from the network. Run the Ping command. (In a Command/DOS window, type ping and the IP address of the unit). If you receive: Reply from : bytes = 32; time = 10 ms..... - this means that the IP address may already be in use by another device on your network. You must obtain a new IP address and reinstall the unit. If you see: Request timed out - this means that the IP address is available for use with your camera. In this case, check all cabling and reinstall the unit. Possible IP address conflict with another device on the same subnet The static IP address in the camera is used before the DHCP server sets a a dynamic address. This means that if the same default static IP address is also used by another device, there may be problems accessing the camera. To avoid this, set the static IP address to 0.0.0.0. 1) Move the camera to an isolated network or to one with no DHCP or BOOTP server. Set the IP address again, using the AXIS IP Utility (see the Installation Guide) or the ARP/Ping commands. 2) Access the unit and disable DHCP in the TCP/IP settings. Return the unit to the main network. The unit now has a fixed IP address that will not change. 3) As an alternative to 2), if dynamic IP address via DHCP or BOOTP is required, select the required service and then configure IP address change notification from the network settings. Return the unit to the main network. The unit will now have a dynamic IP address, but will notify you if the address changes. Test the network cable by connecting it to another network device, then Ping that device from your workstation. See the instructions above. Connect the network cable and check that the SSID and security settings are identical in the camera and in the access point. 41 The camera is located on a different subnet The IP address is being used by another device The camera cannot be accessed from a browser The IP address has been changed by DHCP Other networking problems The AXIS 207W cannot be accessed on the wireless network from a browser The wireless settings in the AXIS 207W do not match those in the wireless access point. Support for 802.11g disabled or missing. Check that the wireless access point supports the 802.11g standard and that this is enabled. Wireless access point requires MAC address registration. Check if the AXIS 207W's MAC address (this is the same as the product's serial number) needs to be registered in the wireless access point, before being allowed to access the wireless network. Check the access point's settings and/or documentation. To configure your broadband router to allow incoming data traffic to the camera: Enable the NAT-traversal feature which will attempt to automatically configure the router to allow access to the camera. This is enabled from Setup > System Options > Network > TCP/IP Advanced. Check the Internet firewall with your system administrator. Check if you need to configure the default router settings. Camera is accessible locally, but not externally Broadband router configuration Firewall protection Default routers required 42 AXIS 207/207W - Troubleshooting Problems with the MPEG-4 format No MPEG-4 displayed in the client Check that the correct network interface is selected in the AMC control panel applet (network tab).

AXIS 207/207W - Troubleshooting Slow image update Poor performance Configuring, e.g. pre-buffers, motion detection, high-resolution images, high frame rates, etc, will reduce the performance of the camera. Poor performance may be caused by e.g. heavy network traffic, multiple users accessing the unit, low performance clients, use of features such as Motion Detection, Event handling, Image rotation other than 180 degrees. For the AXIS 207W, a poor wireless environment may also affect performance. 43 Poor quality snapshot images Screen incorrectly configured on your In Display Properties, configure your screen to show at least 65000 colors, i.e. at least workstation 16-bit. Using only 16 or 256 colors will produce dithering artifacts in the image. Browser freezes Netscape 7.x or Mozilla 1.4 (or later) Lower the image resolution. can sometimes freeze on a slow computer Problems uploading files Limited space Motion Detection triggers unexpectedly Changes in luminance Motion detection is based upon changes in luminance in the image. This means that if there are sudden changes in the lighting, motion detection may be triggered mistakenly. Lower the sensitivity setting to avoid problems with luminance. Check the sound card in the PC. Ensure that the mute button is not pressed and the volume settings are correct. The volume of the microphone is either too high or too low. Change the volume for the microphone in the toolbar on the Live View page. Too many users/clients connected to the camera may affect the sound quality adversely. Try limiting the number of clients allowed to connect under Basic Configuration > Users. Reduce the number of listeners and viewers and decrease the image resolution and compression. It is recommended that the camera's time setting is synchronized with an NTP Server. This is enabled under System Options > Date & Time. There is only limited space available for the upload of your own files. Try deleting existing files to free up space.

AXIS 207/207W - Glossary of Terms 47 Glossary of Terms ActiveX - A standard that enables software components to interact with one another in a networked environment, regardless of the language(s) used to create them. Web browsers may come into contact with ActiveX controls, ActiveX documents, and ActiveX scripts. ActiveX controls are often downloaded and installed automatically as required. AF (Autofocus) - A system by which the camera lens automatically focuses on a selected part of the subject. Angle - The field of view, relative to a standard lens in a 35mm still camera, expressed in degrees, e.g. 30°. For practical purposes, this is the area that a lens can cover, where the angle of view is determined by the focal length of the lens. A wide-angle lens has a short focal length and covers a wider angle of view than standard or telephoto lenses, which have longer focal lengths. ARP (Address Resolution Protocol) - This protocol is used to associate an IP address to a hardware MAC address. A request is broadcast on the local network to discover the MAC address for an IP address. ARTPEC (Axis Real Time Picture Encoder) - This chip is used for image compression. ASIC (Application Specific Integrated Circuit) - A circuit designed for a specific application, as opposed to a general purpose circuit, such as a microprocessor. Aspect ratio - A ratio of width to height in images. A common aspect ratio used for television screens and computer monitors is 4:3. High-definition television (HDTV) uses an aspect ratio of 9:16. Autoiris (or DC-Iris) - This special type of iris is electrically controlled by the camera, to automatically regulate the amount of light allowed to enter. AVI (Audio Video Interleave) - A video format that supports simultaneous playback of audio and video. Bitmap - A bitmap is a data file representing a rectangular grid of pixels. It defines a display space and color for each pixel (or "bit") in the display space. This type of image is known as a "raster graphic." GIF's and JPEG's are examples of image file types that contain bitmaps. Because a bitmap uses this fixed raster method, it cannot easily be rescaled without losing definition. Conversely, a vector graphic image uses geometrical shapes to represent the image, and can thus be quickly rescaled. Bit rate - The bit rate (in kbit/s or Mbit/s) is often referred to as speed, but actually defines the number of bits/time unit and not distance/time unit. Bluetooth - Bluetooth is an open standard for wireless transmission of voice and data between mobile devices (PCs, handheld computers, telephones and printers). Bonjour - Also known as zero-configuration networking, Bonjour enables devices to automatically discover each other on a network, without having to enter IP addresses or configure DNS servers. Bonjour is a trademark of Apple Computer, Inc.. Broadband - In network engineering terms, this describes transmission methods where two or more signals share the same carrier. In more popular terminology, broadband is taken to mean high-speed data transmission. CCD (Charged Coupled Device) - This light-sensitive image device used in many digital cameras is a large integrated circuit that contains hundreds of thousands of photo-sites (pixels) that convert light energy into electronic signals. Its size is measured diagonally and can be 1/4", 1/3", 1/2" or 2/3". CGI (Common Gateway Interface) - A specification for communication between a web server and other (CGI) programs. For example, a HTML page that contains a form might use a CGI program to process the form data once it is submitted. CIF (Common Intermediate Format) - CIF refers to the analog video resolutions 352x288 pixels (PAL) and 352x240 pixels (NTSC). See also Resolution. Client/Server - Client/server describes the relationship between two computer programs in which one program, the client, makes a service request from another program, the server, which fulfils the request. Typically, multiple client programs share the services of a common server program. A web browser is a client program that requests services (the sending of web pages or files) from a web server. CMOS (Complementary Metal Oxide Semiconductor) - A CMOS is a widely used type of semiconductor that uses both negative and positive circuits. Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor. CMOS image sensors also allow processing circuits to be included on the same chip, an advantage not possible with CCD sensors, which are also much more expensive to produce. Codec - In communications engineering, a codec is usually a coder/decoder. Codecs are used in integrated circuits or chips that convert e.g. analog video and audio signals into a digital format for transmission. The codec also converts received digital signals back into analog format. A codec uses analog-to-digital conversion and digital-to-analog conversion in the same chip. Codec can also mean compression/decompression, in which case it is generally taken to mean an algorithm or computer program for reducing the size of large files and programs. Compression - See Image Compression. Contrast - Defines the degree of difference between the lightest and darkest parts of an image or video stream. DC-Iris - This special type of iris is electrically controlled by the camera, to automatically regulate the amount of light 48 AXIS 207/207W - Glossary of Terms allowed to enter. DHCP (Dynamic Host Configuration Protocol) - DHCP is a protocol that lets network administrators automate and centrally manage the assignment of Internet Protocol (IP) addresses to network devices in a network. DHCP uses the concept of a "lease" or amount of time that a given IP address will be valid for a computer. The lease time can vary, depending on how long a user is likely to require the network connection at a particular location. DHCP also supports static addresses for e.g. computers running web servers, which need a permanent IP address. DNS (Domain Name System) - DNS is used to locate and translate Internet domain names into IP (Internet Protocol) addresses. A domain name is a meaningful and easy-to-remember name for an Internet address. For example the domain name www.example.com is much easier to remember than 192.0.34.166. The translation tables for domain names are contained in Domain name servers. Domain Server - Domains can also be used by organizations who wish to centralize the management of their (Windows) computers. Each user within a domain has an account that usually allows them to log in to and use any computer in the domain, although restrictions may also apply. The domain server is the server that authenticates the users on the network. Duplex - See Full-duplex. Ethernet - Ethernet is the most widely installed local area network technology. An Ethernet LAN typically uses special grades of twisted pair wires. The most commonly installed Ethernet systems are 10BASE-T and 100BASE-T10, which provide transmission speeds up to 10 Mbps and 100 Mbps respectively. ETRAX (Ethernet Token Ring AXIS) - Axis' own microprocessor. Factory default settings - These are the settings that originally applied for a device when it was first delivered from the factory. If it should become necessary to reset a device to its factory default settings, this will, for many devices, completely reset any settings that were changed by the user. Firewall - A firewall works as a barrier between networks, e.g. between a Local Area Network and the Internet. The firewall ensures that only authorized users are allowed to access the one network from the other. A firewall can be software running on a computer, or it can be a standalone hardware device. Focal length - Measured in millimetres, the focal length of a camera lens determines the width of the horizontal field of view, which in turn is measured in degrees. FTP (File Transfer Protocol) - An application protocol that uses the TCP/IP protocols. It is used to exchange files between computers/devices on networks. Frame - A frame is a complete video image. In the 2:1 interlaced scanning format of the RS-170 and CCIR formats, a frame is made up of two separate fields of 262.5 or 312.5 lines interlaced at 60 or 50 Hz to form a complete frame, which appears at 30 or 25 Hz. In video cameras with a progressive scan, each frame is scanned line-by-line and not interlaced; most are also displayed at 30 and 25 Hz. Frame rate - The frame rate used to describe the frequency at which a video stream is updated is measured in frames per second (fps). A higher frame rate is advantageous when there is movement in the video stream, as it maintains image quality throughout. Full-duplex - Transmission of data in two directions simultaneously. In an audio system this would describe e.g. a telephone systems. Half-duplex also provides bi-directional communication, but only in one direction at a time, as in a walkie-talkie system. See also Simplex. Gain - Gain is the amplification factor and the extent to which an analog amplifier boosts the strength of a signal. Amplification factors are usually expressed in terms of power. The decibel (dB) is the most common way of quantifying the gain of an amplifier. Gateway - A gateway is a point in a network that acts as an entry point to another network. In a corporate network for example, a computer server acting as a gateway often also acts as a proxy server and a firewall server. A gateway is often associated with both a router, which knows where to direct a given packet of data that arrives at the gateway, and a switch, which furnishes the actual path in and out of the gateway for a given packet. GIF (Graphics Interchange Format) - GIF is one of the most common file formats used for images in web pages. There are two versions of the format, 87a and 89a. Version 89a supports animations, i.e. a short sequence of images within a single GIF file. A GIF89a can also be specified for interlaced presentation. GOV (Group Of VOPs) - A group of VOP's is the basic unit of an MPEG-4 video stream. The GOV contains different types and numbers of VOP's (I-VOP's, P-VOP's, etc) as determined by the GOV length and GOV structure. See also VOP. GOV length - The GOV length determines the number of images (VOP's) in the GOV structure. See also GOV and VOP. GOV structure - The GOV structure describes the composition of an MPEG-4 video stream, as regards the type of images (I-VOP's or P-VOP's) included in the stream, and their internal order. See also GOV and VOP. Half-duplex - See Full-duplex. HTML (Hypertext Markup Language) - HTML is the set of "markup" symbols or codes inserted in a file intended for display in web browser. The markup tells the browser how to display the page's words and images for the user. AXIS 207/207W - Glossary of Terms HTTP (Hypertext Transfer Protocol) - HTTP is the set of rules for exchanging files (text, graphic images, sound, video, and other multimedia files) on the web. The HTTP protocol runs on top of the TCP/IP suite of protocols. Hub - A (network) hub is used to connect multiple devices to the network. The hub transmits all data to all devices connected to it, whereas a switch will only transmit the data to the device it is specifically intended for. IEEE 802.11 - A family of standards for wireless LANs. The 802.11 standard supports 1 or 2 Mbit/s transmission on the 2.4 GHz band. IEEE 802.11b specifies an 11 Mbit/s data rate on the 2.4 GHz band, while 802.11a allows up to 54 Mbit/s on the 5 GHz band. Image compression - Image compression minimizes the file size (in bytes) of an image. Two of the most common compressed image formats are JPEG and GIF. Interlacing - Interlaced video is video captured at 50 pictures (known as fields) per second, of which every 2 consecutive fields (at half height) are then combined into 1 frame. Interlacing was developed many years ago for the analog TV world and is still used widely today. It provides good results when viewing motion in standard TV pictures, although there is always some degree of distortion in the image. To view interlaced video on e.g. a computer monitor, the video must first be de-interlaced, to produce progressive video, which consists of complete images, one after the other, at 25 frames per second. See also Progressive scan. IP (Internet Protocol) - The Internet Protocol is a method transmitting data over a network. Data to be sent is divided into individual and completely independent "packets." Each computer (or host) on the Internet has at least one address that uniquely identifies it from all others, and each data packet contains both the sender's address and the receiver's address. The Internet Protocol ensures that the data packets all arrive at the intended address. As IP is a connectionless protocol, which means that there is no established connection between the communication end-points, packets can be sent via different routes and do not need to arrive at the destination in the correct order. Once the data packets have arrived at the correct destination, another protocol - Transmission Control Protocol (TCP) - puts them in the right order. See also TCP. IP Address - An IP address is simply an address on an IP network used by a computer/device connected to that network. IP addresses allow all the connected computers/devices to find each other and to pass data back and forth. To avoid conflicts, each IP address on any given network must be unique. An IP address can be assigned as fixed, so that it does not change, or it can be assigned dynamically (and automatically) by DHCP. An IP address consists of four groups (or quads) of decimal digits separated by periods, e.g. 130.5.5.25. Different parts of the address represent different things. Some part will represent the network number or address, and some other part will represent the local machine address. See also IP (Internet Protocol). I-VOP - See VOP. JPEG (Joint Photographic Experts Group) - Together with the GIF file format, JPEG is an image file type commonly used on the web. A JPEG image is a bitmap, and usually has the file suffix '.jpg' or ".jpeg." When creating a JPEG image, it is possible to configure the level of compression to use. As the lowest compression (i.e. the highest quality) results in the largest file, there is a trade-off between image quality and file size. kbit/s (kilobits per second) - A measure of the bit rate, i.e. the rate at which bits are passing a given point. See also Bit rate. LAN (Local Area Network) - A LAN is a group of computers and associated devices that typically share common resources within a limited geographical area. Linux - Linux is an open source operating system within the Unix family. Because of its robustness and availability, Linux has won popularity in the open source community and among commercial application developers. MAC address (Media Access Control address) - A MAC address is a unique identifier associated with a piece of networking equipment, or more specifically, its interface with the network. For example, the network card in a computer has its own MAC address. Manual iris - This is the opposite to an autoiris, i.e. the camera iris must be adjusted manually to regulate the amount of light allowed to reach the image sensor. Mbit/s (Megabits per second) - A measure of the bit rate, i.e. the rate at which bits are passing a given point. Commonly used to give the "speed" of a network. A LAN might run at 10 or 100 Mbit/s. See also Bit rate. Monitor - A monitor is very similar to a standard television set, but lacks the electronics to pick up regular television signals. Motion JPEG - Motion JPEG is a simple compression/decompression technique for networked video. Latency is low and image quality is guaranteed, regardless of movement or complexity of the image. Image quality is controlled by adjusting the compression level, which in turn provides control over the file size, and thereby the bit rate. High-quality individual images from the Motion JPEG stream are easily extracted. See also JPEG. Megapixel - See Pixel. MPEG (Moving Picture Experts Group) - The Moving Picture Experts Group develops standards for digital video 49 50 AXIS 207/207W - Glossary of Terms and audio compression. It operates under the auspices of the International Organization for Standardization (ISO). The MPEG standards are an evolving series, each designed for a different purpose. MPEG-2 - MPEG-2 is the designation for a group of audio and video coding standards, and is typically used to encode audio and video for broadcast signals, including digital satellite and Cable TV. MPEG-2, with some modifications, is also the coding format used by standard commercial DVD movies. MPEG-4 - MPEG-4 is a group of audio and video coding standards and related technology. The primary uses for the MPEG-4 standard are web (streaming media) and CD distribution, conversational (videophone), and broadcast television. Most of the features included in MPEG-4 are left to individual developers to decide whether to implement them or not. This means that there are probably no complete implementations of the entire MPEG-4 set of standards. To deal with this, the standard includes the concept of "profiles" and "levels", allowing a specific set of capabilities to be defined in a manner appropriate for a subset of applications. Multicast - Bandwidth-conserving technology that reduces bandwidth usage by simultaneously delivering a single stream of information to multiple network recipients. Multiplexer - A multiplexer is a high-speed switch that provides full-screen images from up to 16 analog cameras. Multiplexers can playback everything that happened on any one camera with no interference from the other cameras on the system. Network connectivity - The physical (wired or wireless) and logical (protocol) connection of a computer network or an individual device to a network, such as the Internet or a LAN. NTSC (National Television System Committee) - NTSC is the television and video standard in the United States. NTSC delivers 525 lines at 60 half-frames/second. OEM (Original Equipment Manufacturer) - This is a designation for companies that manufacture equipment which is then marketed and sold to other companies under their own names. PAL (Phase Alternating Line) - PAL is the dominant television standard in Europe. PAL delivers 625 lines at 50 half-frames/second. PEM (Privacy Enhanced Mail) - An early standard for securing electronic mail. The PEM-format is often used for representing an HTTPS certificate or certificate request. Ping - Ping is a basic network program used diagnostically to check the status of a network host or device. Ping can be used to see if a particular network address (IP address or host name) is occupied or not, or if the host at that address is responding normally. Ping can be run from e.g. the Windows Command prompt or the command line in Unix. Pixel - A pixel is one of the many tiny dots that make up a digital image. The colour and intensity of each pixel represents a tiny area of the complete image. PoE (Power over Ethernet) - Power over Ethernet provides power to a network device via the same cable as used for the network connection. This is very useful for IP-Surveillance and remote monitoring applications in places where it may be too impractical or expensive to power the device from a power outlet. PPP (Point-to-Point Protocol) - A protocol that uses a serial interface for communication between two network devices. For example, a PC connected by a phone line to a server. PPTP (Point-to-Point Tunnelling Protocol) - A protocol (set of communication rules) that allows corporations to extend their own corporate network through private "tunnels" over the public Internet. In this way a corporation can effectively use a WAN (Wide Area Network) as a large single LAN (Local Area Network). This kind of interconnection is known as a virtual private network (VPN). Pre/post alarm images - The images from immediately before and after an alarm. These images are stored in a buffer for later retrieval. Progressive scan - Progressive scan, as opposed to interlaced video, scans the entire picture, line by line every sixteenth of a second. In other words, captured images are not split into separate fields as in interlaced scanning. Computer monitors do not need interlace to show the picture on the screen, but instead show them progressively, on one line at a time in perfect order, i.e. 1, 2, 3, 4, 5, 6, 7 etc., so there is virtually no "flickering" effect. In a surveillance application, this can be critical when viewing detail within a moving image, such as a person running. A high-quality monitor is required to get the best from progressive scan. See also Interlacing. Protocol - A special set of rules governing how two entities will communicate. Protocols are found at many levels of communication, and there are hardware protocols and software protocols. Proxy server - In an organisation that uses the Internet, a proxy server acts as an intermediary between a workstation user and the Internet. This provides security, administrative control, and a caching service. Any proxy server associated with a gateway server, or part of a gateway server, effectively separates the organisation's network from the outside network and the local firewall. It is the firewall server that protects the network against outside intrusion. A proxy server receives requests for Internet services (such as web page requests) from many users. If the proxy server is also a cache server, it looks in its local cache of previously downloaded web pages. If it finds the page, it is
