When using Half-duplex mode, this button toggles between allowing you to speak and listen. The first icon indicates that you can talk and the speaker attached to the camera will play your voice. The second indicates that you will hear audio from the camera, but no audio will be sent to any web clients. When in simplex talk mode, the icon toggles between allowing you to speak and is dimmed when you do not want other clients to receive any audio. AXIS 210/210A/211/211A - Video Streams 13 Video Streams The AXIS 210/210A/211/211A provides several different image and video formats. The type to use depends on your requirements and on the properties of your network. The Live View page in the AXIS 210/210A/211/211A provides access to Motion JPEG and MPEG-4 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. Video Stream Types Motion JPEG This format uses standard JPEG still images in 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 also provides excellent image quality and access to each and every individual image contained in the stream. Note also that multiple clients accessing Motion JPEG streams can use different image settings. MPEG-4 This is a video compression standard that makes good use of bandwidth, and which can provide high-quality video streams at less than 1 Mbit/s. The MPEG-4 standard provides scope for a large range of different coding tools for use by various applications in different situations, and the AXIS 210/210A/211/211A provides certain subsets of these tools. These are represented as Video object types, which are selected for use with different viewing clients. The supported video object types are: · Simple - sets the coding type to H.263, as used by e.g. QuickTimeTM. · Advanced Simple - sets the coding type to MPEG-4 Part 2, as used by AMC (AXIS Media Control) When using MPEG-4 it is also possible to control the bit rate, which in turn allows the amount of bandwidth usage to be controlled. CBR (Constant Bit Rate) is used to achieve a specific bit rate by varying the quality of the MPEG-4 stream. When using VBR (Variable Bit Rate), the quality of the video stream is kept as constant as possible, at the cost of a varying bit rate. Notes: ·MPEG-4 is licensed technology. The AXIS 210/210A/211/211A includes one viewing client license. Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis reseller. ·All clients viewing the MPEG-4 stream must use the same set of coding tools. 14 AXIS 210/210A/211/211A - Video Streams MPEG-4 protocols and communication methods To deliver live streaming video over IP networks, various combinations of transport protocols and broadcast methods are employed. · RTP (Realtime Transport Protocol) is a protocol that allows programs to manage the real-time transmission of multimedia data, via unicast or multicast. · RTSP (Real Time Streaming Protocol) serves as a control protocol, to negotiate which transport protocol to use for the stream. RTSP is thus used by a viewing client to start a unicast session, see below. · UDP (User Datagram Protocol) is a communications protocol that offers limited service for exchanging data in a network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control Protocol (TCP). The advantage of UDP is that it is not required to deliver all data and may drop network packets when there is e.g. network congestion. This is suitable for live video, as there is no point in re-transmitting old information that will not be displayed anyway. · Unicasting is communication between a single sender and a single receiver over a network. This means that the video stream goes independently to each user, and each user gets their own stream. A benefit of unicasting is that if one stream fails, it only affects one user. · Multicast is bandwidth-conserving technology that reduces bandwidth usage by simultaneously delivering a single stream of information to multiple network recipients. This technology is used primarily on delimited networks (intranets), as each user needs an uninterrupted data flow and should not rely on network routers. How to stream MPEG-4 Deciding on the combination of protocols and methods to use depends on your viewing requirements, and on the properties of your network. Setting the preferred method(s) is done in the control applet for AMC, which is found in the Windows Control Panel. When this has been set, AMC will test all the selected methods in the specified order, until the first functioning one is found. RTP+RTSP This method (actually RTP over UDP and RTSP over TCP) should be your first consideration for live video, especially when it is important to always have an up-to-date video stream, even if some images do get dropped. This can be configured as multicast or unicast. Multicasting provides the most efficient usage of bandwidth, especially when there are large numbers of clients viewing simultaneously. Note however, that a multicast broadcast cannot pass a network router unless the router is configured to allow this. It is thus not possible to multicast over e.g. the Internet. AXIS 210/210A/211/211A - Video Streams Unicasting should be used for video-on-demand broadcasting, so that there is no video traffic on the network until a client connects and requests the stream. However, as more and more unicast clients connect, the traffic on the network will increase and may cause congestion. Although there is a maximum of 20 unicast viewers, note that all multicast users combined count as 1 unicast viewer. RTP/RTSP This unicast method is RTP tunneled over RTSP. This can be used to exploit the fact that it is relatively simple to configure firewalls to allow RTSP traffic. RTP/RTSP/HTTP or RTP/RTSP/HTTPS These two methods can also be used to traverse firewalls. Firewalls are commonly configured to allow the HTTP protocol, thus allowing RTP to be tunneled. 15 The AXIS Media Control The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) from the AXIS 210/210A/211/211A is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer for Windows. This ActiveX component is automatically installed on first use, after which it can be configured by opening the AMC Control Panel applet from the Windows Control Panel. Alternatively, right-click the video image in Internet Explorer. Other methods of accessing the video stream Video/images from the AXIS 210/210A/211/211A can also be accessed in the following ways: · If supported by the client, the AXIS 210/210A/211/211A can use Motion JPEG server push to display video. This option maintains an open HTTP connection to the browser and sends data as and when required, for as long as required. · As single 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 decoder 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 Unicast via RTSP, tunneled via HTTPS: axrtsphttps:///mpeg4/media.amp Multicast: axrtpm:///mpeg4/media.amp 16 AXIS 210/210A/211/211A - Video Streams Other MPEG-4 clients Although it may be possible to use other clients to view the MPEG-4 stream, this is not guaranteed by Axis. For some other clients, e.g. QuickTimeTM the Video Object Type must be set to Simple. It may also be necessary to adjust the advanced MPEG-4 settings. To assess the video stream from e.g. QuickTimeTM the following path can be used: rtsp:///mpeg4/media.amp This path is for all supported methods, and the client will negotiate with the AXIS 210/210A/211/211A to determine exactly which transport protocol to use. Audio Stream Types (AXIS 210A/211A only) The stream types for audio are: · G.711 - International standard for encoding wired-telephone audio. Uses PCM samples to compress audio where higher signal values are compressed more than lower values. In Axis products, this sets the coding type to µ-law 64 kbit/s. · G.726 - Uses PCM samples to code the difference between samples (ADPCM). Reduces bandwidth without losing too much useful audio. In Axis products, this sets the coded bit rate to 24 or 32 kbit/s. All stream types are ITU-T standards and operate on frequencies up to 4 kHz. Audio transmission methods (AXIS 210A/211A only) The audio stream can be accessed in the Live View page via Motion JPEG or MPEG-4. Using Motion JPEG The basic audio transmission method used in conjunction with Motion JPEG video streaming is transmission over HTTP. The video and audio streams are not synchronized when using Motion JPEG, so the streams may be slightly out of sync. The latency in any stream should be low, but this will depend on the network infrastructure. Using MPEG-4 When using MPEG-4, audio is streamed using the same protocol as the video stream. When audio is transmitted using MPEG-4, the AXIS 210A/211A sends synchronization information along with the streams to the client performing the synchronization. Note: Audio is streamed from the client to the server over HTTP when using Motion JPEG and MPEG-4. AXIS 210/210A/211/211A - Video Streams 17 Accessing the Audio Streams In addition to accessing audio in the Live View page using AMC, audio from the AXIS 210A/211A can also be accessed in the following ways: HTTP API You can read about accessing audio for the other protocols through the HTTP-API at http://www.axis.com/techsup QuickTime/Windows Media Player It is possible to use QuickTime and Windows Media Player to listen to the audio stream using the same methods to access video streams. 18 AXIS 210/210A/211/211A - Setup Tools Setup Tools This section describes how to configure the cameras, 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.

Setup tools AXIS 210/210A/211/211A - Video & Image settings 19 Video & Image settings The following descriptions offer examples of the features available in the AXIS 210/210A/211/211A. For details of each setting, please refer to the online help available to access the online help. from the setup tools. Click Image Settings Image Appearance Adjust these settings to optimize the video images according to your requirements. All configuration of images and overlays will affect the camera's overall performance, depending on how it is used and on the available bandwidth. Lower compression improves video image quality, but increases the bandwidth. The video image can be rotated and fine-tuned by adjusting the color level, the brightness, and the contrast. Please see the online help for further information on these settings. Changed video image settings have immediate effect on the MPEG-4 stream, but the Motion JPEG stream will have to be started (or restarted) before the settings take effect. 20 AXIS 210/210A/211/211A - Video & Image settings Text Overlay Settings Include date, time and/or text of your choice to be viewed on the image. The color of the text may be set to white or black, while background color may be set to white, black, transparent or semitransparent. The position of the text is set either to the top or the bottom of the image. Video Stream Define the maximum video stream time per session in seconds, minutes or hours. When the set time has expired, a new stream can be started by refreshing the page in the Web browser. For unlimited video stream time, set this value to 0. This setting is only applicable to Motion JPEG. The frame rate allowed to each viewer can also be limited, to avoid bandwidth problems on the network. Test To preview the image before saving, click Test. Note that the preview image will be in JPEG format, even though the settings are valid both for Motion JPEG and MPEG-4. Overlay/Mask Settings Overlay/Mask Type When using an image overlay, select from the following options the type to use: Text, date and time overlays Overlay image · Uploaded image as overlay usually used to provide extra information in the video image. · Configurable areas as privacy masks - up to 3 areas are used to conceal parts of the video image. The difference between an overlay and a privacy mask is that a privacy mask cannot be bypassed by accessing the video stream with the help of the AXIS HTTP API, whereas an overlay can. Selecting the overlay/mask type will display further settings available for the selected type. See the online help for further information. AXIS 210/210A/211/211A - Video & Image settings 21 Upload and use an overlay To upload an overlay image to the camera: 1. Select Uploaded image as overlay in the drop-down list for Overlay/Mask Type.

Overlay image requirements Image Formats · · Windows 24-bit BMP (full color) Windows 4-bit BMP (16 colors) Image Size The height and width of the overlay image in pixels must be exactly divisible by 4. There are a number of limitations when using overlay images, such as the size and positioning of images. Please refer to the online help for more information. Configure area as privacy mask The 3 configurable areas available for use as privacy masks show as solid areas of color in the image. These areas cannot be bypassed via the AXIS HTTP API. Enable the area(s) by checking the Enable box, and then set the width, height and color. Setting the coordinates x and y sets the position of the upper left corner of the area. 22 AXIS 210/210A/211/211A - Video & Image settings Advanced Settings These pages provide various settings for fine-tuning the video image. Note that the advanced settings available depend on the camera model. Camera Settings To compensate for the lighting conditions, the white balance and exposure control can be adjusted. If available, DC-Iris should always be enabled except during focusing, or when using a non-DC-Iris lens. The settings for Low-light behavior determine how the cameras will behave at low light levels. These settings all affect video image quality and are basically a measure of how much noise to allow in the video images. Please see the online help for further instructions on these settings. AXIS 210/210A/211/211A - Video & Image settings 23 MPEG-4 Settings Tools for adjusting the MPEG-4 settings and for controlling the video bit rate. The MPEG-4 standard provides many different coding tools for various applications in different situations. As most MPEG-4 clients do not support all of these tools, it is usual to instead define and use subsets for different clients or groups of clients. These settings allow you to define the type of viewing client to use. Adjusting the maximum bit rate and setting it to a variable or constant is a good way of controlling the bandwidth used by the MPEG-4 video stream. For more information on these advanced settings, please see Video Streams, on page 13, and the online help. AXIS Media Control The AXIS Media Control (AMC) is installed automatically the first time the camera is accessed from a browser. 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, such as push-to-talk. Please see the readme file included in the tool for more information. 24 AXIS 210/210A/211/211A - Audio (AXIS 210A/211A only) Audio (AXIS 210A/211A only) The AXIS 210A/211A can transmit audio to other clients using an external microphone and can play audio received from other clients by attaching a speaker. The Setup page for the AXIS 210A/211A has an additional menu item called Audio, which allows different audio configurations to be set up, e.g. full duplex, half duplex and simplex. Note: The speaker attached to the audio output of the AXIS 210A/211A must have a built-in amplifier, e.g. some PC speakers. Client PC AXIS 210A/211A TCP/IP Network AXIS 210A/211A AXIS 210A/211A An example of a network using AXIS 210A/211A cameras to transmit audio and video across the network. Audio Settings This section describes how to configure the basic audio settings for the AXIS 210A/211A, e.g. set the communication mode and adjust the sound levels in the microphone and speaker connected to the camera. Enable Audio Check this box to enable audio in the AXIS 210A/211A. Audio Channels There are two mono audio channels between the AXIS 210A/211A and other clients, one for receiving audio and one for transmitting audio. Each audio channel can be turned on or off, which means that there are four audio mode options that can be used. AXIS 210/210A/211/211A - Audio (AXIS 210A/211A only) Full-duplex mode means you can transmit and receive audio (talk and listen) at the same time, without having to use any of the controls. This is just like having a telephone conversation. The only controls you may wish to use are the mute buttons to turn off the sound, and the sliders, to adjust the input/output volume levels. This mode requires the client PC to have a sound card with full-duplex audio support. If your available bandwidth is 0.2 Mbit/s or less, using Half-duplex mode is recommended instead. Half-duplex mode also transmits and receives audio in both directions, but only in one direction at a time. This means that you must select when to receive or transmit audio with the help of the push-to-talk button. To speak, press and hold the button (check that the microphone is not muted). When finished speaking, release the button. You will now be receiving audio from the other end of the connection. Note that the push-to-talk button is configured from AMC, see AXIS Media Control, on page 23. It is also possible to configure the push-to-talk button so that it toggles between speaking and listening modes. Half-Duplex mode is best if you only have limited bandwidth available. When selecting Simplex - AXIS 210A/211A speaker only mode, the speaker connected to the camera will play audio, but no audio will be transmitted from the camera to other web clients. This could be used to e.g. provide spoken instructions to a person seen in the camera. This mode requires you to use the push-to-talk button. Simplex - AXIS 210A/211A microphone only mode transmits audio only from the AXIS 210A/211A to web clients. It will not receive audio from any other web clients. This can be used in remote monitoring, web attractions etc., to provide live audio, as well as video, of a monitored situation. When using half-duplex, the Send the sound from the active client to all other clients option transmits the audio signal from the client that is talking to all the other clients. 25 Audio Input Audio from an external microphone or a line source can be connected to the Line/Mic in jack of the AXIS 210A/211A. The audio source can be set to Internal Microphone, External Microphone or Line. If you are using a microphone, the input sensitivity can be set to High or Low. See Technical Specifications, on page 49 for the exact maximum levels. The Enable microphone power option provides DC power for an external microphone. If using a small electret condenser microphone such as a clip-on mic or a PC microphone, this option needs to be enabled. To use a high impedance dynamic microphone, DC power should not be enabled. DC power will not harm the microphone, but if you are uncertain, try switching it off and on. The default value is DC power enabled. To use a professional microphone requiring 48V phantom power, you need an external power supply and must use a balanced-unbalanced converter (audio transformer) in between. 26 AXIS 210/210A/211/211A - Audio (AXIS 210A/211A only) If there are problems with the sound input being too low or high, adjust the input gain for the microphone attached to the AXIS 210A/211A. Audio Output If the sound from the speaker is too low or high, adjust the output gain for the active speaker attached to the AXIS 210A/211A. When satisfied with the settings, click Save, or click Reset to revert to the previously saved settings. Advanced Audio Settings The Audio Quality Settings allow you to fine-tune the internal or external microphone connected to the AXIS 210A/211A to suit your environment. Enable speech filter improves the sound quality when the microphone is placed close to the person talking and can also help reduce background noise. The filter cuts the lowest and the highest frequencies. The bypass frequency range is approximately 250Hz to 3700Hz (measured at -10dB cut-off break points). Enable echo cancellation - If audio from the speaker is captured by the microphone, this will produce an echo. Enable this option to reduce acoustic echoing. Noise canceling is a way of reducing the background noise when there is no useful audio present. A typical application could be that the camera is set up in a noisy environment, and you are only interested in hearing the sound from the AXIS 210A/211A when someone is speaking close to the microphone. AXIS 210/210A/211/211A - Audio (AXIS 210A/211A only) There are two adjustable parameters available for noise cancellation: · Noise canceller threshold level · Noise canceller attenuation When the incoming sound is louder than the threshold it will pass without being affected. When lower than the threshold, the incoming sound will be reduced by a certain attenuation factor. The threshold level should be set higher than the background noise, but lower than the useful audio. The noise canceller threshold value can be set to High, Medium High, Medium low or Low. A lower threshold will allow most audio to pass, only the weakest background noise will be reduced. A higher threshold will make the noise canceller act on even stronger background noise. At the maximum level - High - there is a risk of reducing useful audio as well. There is thus always a trade-off between noise canceling and sound quality. In other words, increasing the noise canceller attenuation results in deterioration in sound quality. To adjust the threshold and attenuation to an optimum level, change the levels and then listen to the result, repeating as necessary. 27 28 AXIS 210/210A/211/211A - Live View Config Live View Config These are the tools for deciding the layout of the camera's Live View page.

The available options are similar to Internet Explorer except for Server Push. With this method, the camera maintains and controls an open HTTP connection to the browser and sends data as and when required for as long as required.Please see the online help for more information. 31 Viewer settings Checking the Show viewer toolbar displays the viewer toolbar under the video stream in your browser. By checking the Enable MPEG-4 decoder installation box, it is also possible for the Administrator to enable or disable the installation of the MPEG-4 decoder. This is used to prevent the installation of unlicensed copies. Further decoder licenses can be purchased from your Axis dealer. See also AXIS Media Control, on page 23. HTML Examples You can add live video from the cameras to your own web site. The camera can transmit a Motion JPEG or unicast MPEG-4 stream to up to 20 simultaneous connections, although an administrator can restrict this to fewer. If multicast MPEG-4 is used, the video stream will be available to an unlimited number of viewers connected to the parts of the network where multicast is enabled. Please note that a separate MPEG-4 license is required for each viewer. Enter the Video Format, Image Type, Image size and other settings to suit your Web page and click Update. The camera then generates the required source code for your configuration. Copy this code and paste it into your own Web page code. External Video The cameras can also display video images from other Axis network cameras and video servers, directly on the Live View page. These are known as External Video sources. These external video sources are available from the drop-down list on the Live View page. Click the Add button to open the External Video Source Setup dialog, which is used to make all the necessary settings. Enter the IP address or host name of the external video source you wish to add.

AXIS 210/210A/211/211A - Event Configuration 33 Event Configuration An event in the camera is when an Event Type is activated and causes certain actions to be performed. The event type is the set of parameters (or conditions) that specifies how and when which actions will be performed. A common event type is when the camera uploads images when an alarm occurs. Many event types use an Event Server, to e.g. upload images to. This section describes how to set up event servers and event types, i.e. how to configure the cameras to perform certain actions when events (e.g. alarms) occur. Definitions Event type Triggered Event - see page 34 A set of parameters describing how and when the camera will perform certain actions The circumstances that start an event. E.g. on a signal from an external device, such as a door switch or a motion sensor. E.g. at a pre-programmed time. E.g. the upload of images to an FTP server, e-mail notification, etc. Scheduled Event - see page 35 The circumstances that start an event. Action What occurs when the event triggers. Event Servers Event Servers are used to receive e.g. uploaded image files and/or notification messages. To set up Event server connections in your cameras, go to Setup > Event Configuration > Event Servers and enter the required information for the required server type. Server type FTP Server Purpose · Receives uploaded images Information required · · · · · · Descriptive name of your choice Network address (IP address or host name) User Name and Password (for FTP server) Upload path e.g. images/ Port number Use passive mode if there is a firewall between the camera and FTP server · Use temporary file if your FTP server doesn't allow an existing file to be overwritten by a new file with the same name Descriptive name of your choice URL (IP address or host name) User Name and Password (for HTTP server) Proxy address/Proxy port (if required) Proxy User Name and Password (if required) Descriptive name of your choice Network address (IP address or host name) User Name and Password (for TCP server) Port number HTTP Server · Receives notification messages · Receives uploaded images · · · · · · · · · TCP Server · Receives notification messages For details on each setting, please see the online help available from each web page. When the setup is complete, the connection can be tested by clicking the Test button (the connection test takes approximately 10 seconds). 34 AXIS 210/210A/211/211A - Event Configuration Configuring Event Types An Event Type describes how and when the camera will perform certain actions. Example: If somebody passes in front of the camera and an event that uses motion detection has been configured to act on this, the camera can e.g. record and save images to an FTP server, and/or send a notification e-mail to a pre-configured e-mail address with a pre-configured message. Images can be sent as e-mail attachments.
