For information on using Pan/Tilt/Zoom controls, please see page 42. 18 AXIS 282/AXIS 282A - Video and Audio Streams Video and Audio Streams The AXIS 282/AXIS 282A provides several different video and audio stream formats. The type to use depends on your requirements and on the properties of your network. The Live View page in the AXIS 282/AXIS 282A provides access to Motion JPEG and MPEG-4 video and audio streams, as well as to single JPEG images. Other applications and clients can also access these video and audio 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 282/AXIS 282A 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 · Advanced Simple - in Axis products, this sets the coding type to MPEG-4 Part 2 AMC (AXIS Media Control) supports both object types, whilst e.g. QuickTimeTM requires the Simple object type. 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. AXIS 282/AXIS 282A - Video and Audio Streams Notes: ·MPEG-4 is licensed technology. The AXIS 282/AXIS 282A includes one license for the decoder required for viewing in AMC. Installing additional unlicensed copies of this decoder is prohibited. To purchase more decoder licenses, contact your Axis reseller. ·All clients viewing the MPEG-4 stream must use the same image settings. 19 Audio Stream Types The three 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 bitrate to 24 or 32 kbit/s. All stream types are ITU-T standards and operate on frequencies up to 4 kHz. 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 (Real-Time 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. 20 AXIS 282/AXIS 282A - Video and Audio Streams 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. 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, if more and more unicast clients connect simultaneously, the server will at some point become overloaded. There is also a maximum of 20 simultaneous viewers to be considered. 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. The AXIS Media Control The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) and audio from the AXIS 282/AXIS 282A is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer in 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. AXIS 282/AXIS 282A - Video and Audio Streams 21 Other methods of accessing the video stream Video/images from the AXIS 282/AXIS 282A can also be accessed in the following ways: · If supported by the client, the AXIS 282/AXIS 282A 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=CIF · 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 Note: = IP address. Other MPEG-4 clients Although it may be possible to use other clients to view the MPEG-4 stream, it is not guaranteed to work in all cases. 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 282/AXIS 282A to determine exactly which transport protocol to use. Note: = IP address. Audio transmission methods For the AXIS 282A, the audio stream can be accessed in the Live View page when viewing either Motion JPEG or MPEG-4. Using Motion JPEG The basic transmission method of audio 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. 22 AXIS 282/AXIS 282A - Video and Audio Streams 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 product sends synchronization information along with the streams to the client that is performing the synchronization. Note: Audio is streamed from the client to the server over HTTP when using Motion JPEG and MPEG-4. Accessing the Audio Streams In addition to accessing audio in the Live View page using AMC, audio from the AXIS 282A 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.

Overlay image limitations: · The maximum overlay image size supported by the AXIS 282/AXIS 282A is the same as the maximum image resolution. See Technical Specifications, on page 66. · When a text overlay is also used, this reduces the amount of space available to the overlay image. To keep the text readable at lower resolutions, the text overlay occupies proportionally more of the image at lower resolutions. · If the overlay is initially positioned so that part of it is outside the video image, it will be relocated so that it appears over the video image, i.e. it is always the entire image that is displayed. Please see the online help for more information. Use a Privacy Mask To use privacy masks to hide different areas of the video image: 1. Select Configurable areas as privacy mask in the drop-down list for Overlay/Mask Type. New options appear. 2.

Click in the box beside Enable to enable one or more of the masks you have defined and click on Save. 28 AXIS 282/AXIS 282A - Video & Image Settings Advanced - 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 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 the online help. AXIS 282/AXIS 282A - Audio (AXIS 282A only) 29 Audio (AXIS 282A only) The AXIS 282A 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 282A has an additional menu item called Audio, that 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 282A must have a built-in amplifier, e.g. some PC speakers. Audio Settings This section describes how to configure the basic audio settings for the AXIS 282A, e.g. set the communication mode and adjust the sound levels in the microphone and speaker connected to the camera. Enable Audio Check the box Enable Audio to enable audio functionality. Audio Channels There are two mono audio channels between the AXIS 282A 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. 30 AXIS 282/AXIS 282A - Audio (AXIS 282A only) Full-duplex mode means that 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 that the client PC has a sound card with support for full-duplex audio. If your available bandwidth is 0.2 Mbit/s or less, it is recommended that you use Half-duplex mode 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 The AXIS Media Control, on page 20. 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 you select Simplex - AXIS 282A speaker only mode, the speaker connected to the AXIS 282A will play audio, but no audio will be transmitted from the AXIS 282A to other web clients. This could be used to e.g. provide spoken instructions to a person seen in a camera. This mode requires you to use the push-to-talk button. Simplex - AXIS 282A microphone only mode only transmits audio from the AXIS 282A to any 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. Audio Input Audio from an external microphone or a line source can be connected to the MIC pin of the AXIS 282A. The audio source can be set to Microphone or Line. If you are using a microphone, the input sensitivity can be set to High or Low. See Technical Specifications, on page 55 for the exact maximum levels. The Enable microphone power option provides DC power for the external microphone. If you use 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. By 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. AXIS 282/AXIS 282A - Audio (AXIS 282A only) If there are problems with the sound input being too low or high, it is possible to adjust the input gain for the microphone attached to the AXIS 282A. 31 Audio Output If the sound from the speaker is too low or high it is possible to adjust the output gain for the active speaker attached to the AXIS 282A. When satisfied with the settings, click Save, or click Reset to revert to the previously saved settings. Advanced Audio Settings The Advanced Quality Settings allows you to tune the audio input to suit your environment. Enable speech filter improves the sound quality if using a microphone that 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 can reduce the feedback generated when using full duplex. If sound distortion is encountered, turning echo cancellation off may improve the sound quality. Noise canceling is a way of reducing the background noise when there is no useful audio present. A typical application could be when there a noisy environment and you are only interested in hearing the sound when someone is speaking close to a microphone. There are two adjustable parameters available to optimize this function: · Noise canceller threshold value · Noise canceller attenuation 32 AXIS 282/AXIS 282A - Audio (AXIS 282A only) When the incoming sound is louder than the threshold, it will pass without any changes. When lower than the threshold, the incoming sound will be reduced by a certain attenuation factor. The threshold value 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 and Low. A lower threshold will accept most of the 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 a trade-off between noise canceling and sound quality. In other words, increasing the noise canceller attenuation deteriorates sound quality. Adjust the threshold and the attenuation to an optimum by listening and changing the levels.

AXIS 282/AXIS 282A - Event Configuration 37 Event Configuration This section describes how to configure the AXIS 282/AXIS 282A for alarm handling. Various actions can be configured to run when certain types of events occur. Event type Triggered Event (see page 38) A set of parameters describing how and when the Video Server is to perform certain actions - the circumstances that start an event e.g. at a signal from an external device, such as a door switch or a motion sensor e.g. at a pre-programmed time e.g. video images uploaded to an FTP server, email notification sent, etc. Scheduled Event (see page 39) - the circumstances that start an event Action - what occurs when the event runs Event Servers Event Servers are used for e.g. receiving uploaded image files and/or notification messages. To set up Event server for your AXIS 282/AXIS 282A, go to Setup > Event Configuration > Event Servers and enter the required information according to the selected server type. Server type FTP Server Purpose · receives uploaded images Information required · · · · · Descriptive name of your choice User Name and Password (to FTP server) Upload path, e.g. images/ Port number Use passive mode if there is a firewall between the Video Server 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 (address) User Name and Password (to HTTP server) Proxy address/Proxy port (if required) Proxy User Name and Password (if required) HTTP Server · receives notification messages · receives uploaded images TCP Server · receives notification messages · Descriptive name of your choice · User Name and Password (for TCP server) · Port number For details on each setting, please refer to the online help page. available from each web Note: Pre-trigger and Post-trigger buffers will be lost if the connection to the event server fails. When the setup is complete, the connection can be tested by clicking the Test button (the connection test takes approximately 10 seconds). 38 AXIS 282/AXIS 282A - Event Configuration Event Types An Event Type is a set of parameters describing how and when the Video Server is to perform certain actions. Example: If somebody walks past the connected camera, and an event has been configured to act on this, the Video Server can e.g. record and send video images to an FTP server, or send a notification email to a pre-configured email address with a pre-configured message. Video images can be sent as an attachment with the email. Triggered Event A triggered event is activated by e.g: · · · · · a push button connected to an input port on the Video Server detected movement in a configured motion detection window a lost video signal a manually activated action e.g. from an action button in the web interface on restart (reboot) after e.g. power loss How to set up a triggered event This example describes how to set the AXIS 282/AXIS 282A to upload images when the main door is opened: 1. Click Add triggered on the Event types page. 2. Enter a descriptive name for the event, e.g. Main door. 3. Set the priority - High, Normal or Low (see online help files). 4. Select which Video Source the event is to act on, e.g. Video 1 on Main door. 5. Set the Respond to Trigger... parameters when the event is to be active, e.g. only after office hours 6. Select the trigger alternative from the Triggered by... drop-down list, e.g. an Input port with a connected sensor if the door is opened. 7. Set the When Triggered... parameters, i.e. set what the Video Server should do if the main door is opened, e.g. upload images to an FTP server or send an email. 8. Click OK to save the event in the Event Types list. Please see the online help for descriptions of each available option. AXIS 282/AXIS 282A - Event Configuration Pre-trigger and Post-trigger buffers This function is very useful when checking to see what happened immediately before and after a trigger, e.g. 2 minutes before and after a door was opened. Check the Upload images checkbox under Event Types > Add Triggered... > Triggered by... to expand the web page with the available options. Buffer size - Both the AXIS 282 and the AXIS 282A each have a 9 MB buffer. The maximum length of time of the pre-/post-buffer depends on the selected image size and frame rate. Include pre-trigger buffer - images stored internally in the server from the time immediately preceding the trigger. Check the box to enable the pre-trigger buffer, enter the desired length of time and specify the required image frequency. Include post-trigger buffer - contains images from the time immediately after the trigger. Configure as for pre-trigger. Note: If the pre- or post-buffer is too large for the AXIS 282/AXIS 282A's internal memory, the frame rate will be reduced and individual images may be missing. If this occurs, an entry will be created in the unit's log file. 39 Continue image upload (unbuffered) - enable the upload of images for a fixed length of time. Specify the length of time for the uploaded recording, in seconds, minutes or hours, or for as long as the trigger is active. Finally, set the desired image frequency to the maximum (the maximum available) or to a specified frame rate. The frame rate will be the best possible, but might not be as high as specified, especially if uploading via a slow connection. Scheduled Event A Scheduled event can be activated at pre-set times, in a repeating pattern on selected weekdays. How to set up a scheduled event This example describes how to set the Video Server to send an email notification with saved images from a set time: 1. Click Add scheduled on the Event types page. 2. Enter a descriptive name for the event, e.g. Scheduled email. 3. Set the priority (High, Normal or Low). 4. Set the Activation Time parameters (24h clock) when the event should be active, e.g. start on Sundays at 13.00 with a duration of 12 hours. 5. Set the When Activated... parameters i.e. set what the Video Server should do at the specified time e.g. send uploaded images to an email address. 6. Click OK to save the Event in the Event Types list. 40 AXIS 282/AXIS 282A - Event Configuration Please see the online help for descriptions of each available option. Motion Detection In the Motion Detection menu, you can configure the video source(s) for motion detection. The motion detection feature is used to generate an alarm whenever movement occurs (or stops) in the image. The AXIS 282/AXIS 282A can use a maximum of 10 Include/Exclude windows. · Include windows target specific areas within the image · Exclude windows are areas to be ignored within the Include window Once configured, the motion detection windows will appear in a list when motion detection is selected to trigger an event. See How to set up a triggered event above. Note: Using the motion detection feature may decrease overall performance in the Video Server. How to configure Motion Detection This example describes how to configure motion detection: 1. Click Motion Detection in the Event Configuration menu. 2. Click the Configure Included Windows radio button. 3. Click New. 4. Enter a descriptive name of your choice under Windows name. 5. Adjust the size (drag the bottom right-hand corner) and position (click on the text at the top and drag to the desired position). AXIS 282/AXIS 282A - Event Configuration 6. Adjust the Object size, History and Sensitivity profile sliders (see table below for details). Any detected motion within an active window is then indicated by red peaks in the Activity window (the active window has a red frame). 7. Click Save. If there are parts of the Include window that you wish to exclude, click the Configure Excluded Windows radio button and repeat steps 1-8 above. 41 Please use the online help Parameter High for descriptions of each available option. History An object that appears in the region will trigger the motion detection for a long period An object that appears in the region will trigger motion detection for only a very short period Medium to High Size Only very large objects trigger motion detection Even very small objects trigger motion detection Sensitivity Ordinary colored objects against ordinary backgrounds will trigger the motion detection Only very bright objects against a dark background will trigger motion detection Medium to High Low Default values Low Examples: · · · Avoid triggering on small objects in the image by selecting a high size level. To trigger motion detection as long as there is activity in the area, select a high history level. To only detect flashing light, low sensitivity can be selected. In other cases, a high sensitivity level is recommended. Port Status Under Event Configuration > Port Status, there is a list that shows the status for the connected inputs and outputs of the AXIS 282/AXIS 282A. This is for the benefit of an operator, who cannot access the System Options section. Example: If the Normal state for a push button connected to an input is set to Open circuit, as long as the button is not pushed, the state is inactive. If the button is pushed, the state of the input changes to active. 42 AXIS 282/AXIS 282A - Pan Tilt Zoom Pan Tilt Zoom Installing PTZ Devices The AXIS 282/AXIS 282A supports several PTZ devices. Please see www.axis.com for a complete list of supported devices, and to obtain the correct driver. Follow the instructions below to install a PTZ device: 1. Using an appropriate cable, connect the device to your selected port (RS-232 or RS-485). This configurable port is available via the 34 I/O pins. See pages 58 and 59 for more information. 2. In the setup tools, go to Setup > System Options > Ports & Devices and then select the port (RS-232/RS-485) to configure. 3. Select Pan Tilt Zoom from the Usage drop-down list. 4. Click Upload to install a PTZ driver. (PTZ drivers are available from the Axis Web site at www.axis.com) 5. Click Port Options... to modify the port settings. The default values correspond to the values specified by the PTZ driver. 6. From System Options > Ports & Devices, select the port configured for PTZ and then select the video source to use with the device. 7. If required, click the Advanced Options button to make further settings and see the online help. AXIS 282/AXIS 282A - Pan Tilt Zoom Note: Advanced users and application developers can also use the Axis Application Programming Interface and HTTP specification for generic control of PTZ devices using CGI commands or a TCP/IP client. Please refer to the Axis Website at www.axis.com for further information. 43 PTZ Configuration Once PTZ has been installed for the AXIS 282/AXIS 282A, PTZ Configuration now appears in the menu to the left along with the following submenus. Preset Positions A preset position is a pre-defined camera view than can be used to quickly move the camera to a specific location. From Preset Position Setup, use the Pan, Tilt and Zoom (PTZ) controls to steer the camera to the required position. When satisfied with the camera's position, enter a descriptive name. The camera position, iris and focus settings are then saved as a preset position. The position can be assumed at any time, by selecting the preset's name from the Preset positions drop-down list. Preset positions can be selected in Live View, from events and in Sequence mode. One position can be set as the Home position, which is readily accessible by clicking in the box beside Use current position as Home. The position's name will then have (H) added, e.g. Office Entrance (H). 44 AXIS 282/AXIS 282A - Pan Tilt Zoom PTZ Controls If the AXIS 282/AXIS 282A has been appropriately configured, the Live View page will display the controls available for the installed Pan Tilt Zoom (PTZ) device. The administrator can enable/disable the controls for specified users. Video sources Preset positions Tilt bar (relative) The exact controls shown depends on the make and model of PTZ device. There may be e.g. Focus and Iris bars available as well, but the most common controls are; · the Pan bar - moves the camera to the right and left · the Tilt bar - tips the camera up and down · the Zoom bar - zooms the view in and out. Note that this is only available if the camera is fitted with a zoom lens. · the Iris bar - adjusts the brightness of the image Clicking on the bars themselves or on the arrows at the end of the bars will move the camera to a new position. The type of movement and the location of this new position depends on the type of PTZ driver. When controlling the camera using a relative PTZ driver (see the bars in the illustration above) the new position will be relative to the previous position, e.g. left of, below, above, etc. Clicking the bar further from the center results in a larger movement. AXIS 282/AXIS 282A - Pan Tilt Zoom In contrast, when using an absolute driver, each position on the bar (see right) represents a defined position in the device's range of movement, with the center of the bar representing the point midway between the two extremes of movement. Clicking a position directly on the bar moves the camera directly to the new position in one smooth movement. Clicking on the arrows at the ends of a bar causes a stepped, incremental change. 45 Using CGI links to control PTZ devices User-defined CGI links on the Live View page can be used to issue HTTP API requests, e.g. PTZ commands. These links are configured in the Live View Layout settings, see page 34. PTZ Control Modes The PTZ device can also be controlled using click-in-image movement, which has two different types of navigation; Center and Joystick. Center mode means that when clicking in the image, the camera view will center on the absolute position that was clicked. Joystick mode moves the camera in the direction of the mouse pointer. By clicking and holding the mouse button down in the image, the PTZ device moves the camera in that direction, relative to the center of the image. The further from the center the image is clicked, the greater the movement. The camera stops moving when the button is released. Control Panel The Focus and Iris (image brightness) can be adjusted manually by using the control bars, or they can be set for automatic adjustment, by clicking the Auto Iris and Auto Focus buttons. To access the Auto Iris and Auto Focus buttons, click on the Ctrl Panel button. the menu to the right will then appear in the upper left hand corner of the screen. There are also driver specific shortcuts that can appear in the Control Panel. In the screen to the right, a driver has been installed that brings up the Wiper shortcut button, which allows the user to configure and use a windshield wiping action with the AXIS 282/AXIS 282A . 46 AXIS 282/AXIS 282A - Pan Tilt Zoom Preset Positions Also available with many PTZ devices are Preset positions. These presets are selected from the drop-down Source list on the Live View page and will move and/or zoom the camera to a pre-defined position, i.e. to cover an area of particular interest. Events can also be configured to go to preset positions when triggered. For information on setting up preset positions, please see Preset Positions, on page 43 and the online help. Guard Tour A guard tour moves between chosen Preset Positions, one-by-one, in a pre-determined order or randomly, and for configurable time periods. Unlike the Sequence Mode, which is a viewing application under Live View Config (see Live View Config, on page 33), the guard tour sequence will keep running after the user has logged off or closed the Web browser. Advanced Device Settings - The device settings window is for driver specific settings, so the appearance of this window can vary depending on the driver installed. Options that can be configured include: Driver Specific Settings for Video Source 1, Mechanical Limits for Moving Video Source 1, Light Control for Video Source 1, and Extended Driver Specific Settings for Video Source 1. Ctrl Panel - The Panel View Settings contains tools for creating and saving short command buttons are located under Ctrl Panel. These buttons provide direct access to various built-in auxiliary commands provided by the PTZ driver and are displayed in the PTZ Panel. Limits - Define the pan, tilt, zoom and focus limits for the AXIS 282/AXIS 282A. Movements to the left and right, up and down can be restricted to narrow the area under surveillance. The near focus limit can be set to avoid focusing on objects too close to the camera. AXIS 282/AXIS 282A - Pan Tilt Zoom OSD Menu - If the PTZ unit supports an internal configuration menu, this can be accessed using the On-Screen Display (OSD). Configure the analog camera by opening and navigating through its internal menu in this display. 47 PTZ Control Queue Use the PTZ Control Queue window to enable and disable PTZ queueing. This window allows you to set up a queue for viewers wanting to access the AXIS 282/AXIS 282A, and limits the number of viewers and the length of time each viewer can access and control the video stream. For more information on how to set up the control queue, please see the online help. Note also that a viewer who belongs to a group (see Users, on page 49) that has a higher PTZ priority can go in front of other users in the queue and take control of the AXIS 282/AXIS 282A. The order of priority for taking control of the queue is listed below: 48 AXIS 282/AXIS 282A - Pan Tilt Zoom 1. Administrators - An administrator may take the PTZ control regardless of who is currently first in queue. The administrator will be removed from queue 60 seconds after the their last PTZ control command. 2. Event - You can set up the AXIS 282/AXIS 282A to take control of the queue and move to a specific position for 20 seconds when triggered by an alarm. The event will immediately be place first in queue except when an administrator is in control. For more information see How to set up a triggered event, on page 38. 3. Operator - Same as administrator with lower priority. 4. Guard Tour - Guard tour has control of PTZ for an indefinite period of time. It may be overridden by, Operator, Event or administrator. Guard Tour will resume when higher priority groups leaves the queue. For more information see Guard Tour, on page 46. 5. Viewer - Multiple viewers will need to wait for their turn. The viewer has 60 seconds to control PTZ until control is passed to the next viewer in queue. Note: In order to be able to identify different users in the viewer group, cookies need to be enabled on the client. AXIS 282/AXIS 282A - System Options 49 System Options Security User access control is enabled by default, when the administrator sets the root password on first access. New users are authorized with user names and passwords, or the administrator can choose to allow anonymous viewer login to the Live View page, as described below: Users User list displays the authorized users and access levels: Viewer Operator Administrator Provides the lowest level of access, which only allows the user access to the Live View page An Operator can view the Live View page, create and modify event types and adjust certain other settings. The Operator does not have access to the Systems Options configuration pages. An administrator has unrestricted access to the Setup Tools and can determine the registration of all other users. User Settings - check the corresponding checkboxes to enable: · Anonymous viewer login - allows any viewer direct access to the Live View page. · Anonymous PTZ control login - allows any viewer access to the Pan Tilt Zoom controllers on the Live View page (if Pan/Tilt/Zoom is available). IP Address Filtering Checking the Enable IP address filtering box enables the IP address filtering function. Up to 256 IP address entries may be specified (a single entry can contain multiple IP addresses). Click the Add button to add new filtered addresses. When the IP address filter is enabled, addresses added to the list are set as allowed or denied addresses. All other IP addresses not in this list will then be allowed or denied access accordingly, i.e. if the addresses in the list are allowed, then all others are denied access, and vice versa. See also the online help for more information. Note that users from IP addresses that will be allowed must also be registered with the appropriate access rights (User, Operator or Administrator). This is done from Setup > System Options > Security > Users. Referrals - to prevent unauthorized sources from including the video stream from the AXIS 282/AXIS 282A into external Web pages, check the Referrals box and enter the IP address or Host name of the computer that hosts the Web pages with the included video stream. Multiple IP addresses/host names can be defined and are separated by semicolons(;) 50 AXIS 282/AXIS 282A - System Options Notes: ·If the referrals feature is enabled and you wish to also allow normal access to the Live View page, the product's own IP address or host name must be added to the list of allowed referrers. ·Restricting referrers has no effect on an MPEG-4 video stream. To restrict an MPEG-4 stream, IP address filtering must be enabled. ·Restricting referrers is of greatest value when not using IP address filtering. If IP address filtering is used, then the allowed referrers are automatically restricted to those allowed IP addresses. HTTPS For greater security, the AXIS 282/AXIS 282A can be configured to use HTTPS (Hypertext Transfer Protocol over SSL (Secure Socket Layer)). That is, all communication that would otherwise go via HTTP will instead go via an encrypted HTTPS connection. Certificate - to use HTTPS for communication with the AXIS 282/AXIS 282A, a Certificate must be created using one of these methods: · A self-signed certificate can be created in the Video Server, but this does not guarantee the same level of security as an official certificate. · An official certificate issued by a CA (Certificate Authority). A CA issues and manages security credentials and public keys for message encryption. 1. Click either Create self-signed certificate or Create Certificate Request and enter the required information in the provided fields 2. Click OK. 3. Create self-signed certificate generates and installs a certificate which will be displayed under Installed Certificate. Create Certificate Request generates a PEM formatted request which you copy and send to a CA for signing. When the signed certificate is returned, click Install signed certificate... to install the certificate in the AXIS 282/AXIS 282A. 4. Set the HTTPS Connection Policy for the administrator, Operator and Viewer to enable HTTPS connection (set to HTTP by default) Please refer to the home page of your preferred CA for information on where to send the request etc. For more information, please see the online help
