The use of "AXIS 282/AXIS 282A" and "Video Server" thoughout this manual refers to the AXIS 282/AXIS 282A as an integrated component of an end product or system. It includes instructions for integrating, using and managing the AXIS 282/AXIS 282A on your network. Previous experience of networking will be of use when installing and using this product. [. . . ] 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. 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. Check the Upload images checkbox under Event Types > Add Triggered. . . 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. 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. [. . . ] LAN - A local area network (LAN) is a group of computers and associated devices that typically share common resources within a limited geographical area. Linux - A popular operating system that is "open source" and practically free of charge. MPEG-4 - A video compression standard that makes good use of bandwidth, and which can provide DVD-quality video streams at less than 1 Mbit/s. Multicast - A bandwidth-conserving technology that reduces bandwidth usage by simultaneously delivering a single stream of information to multiple network recipients. [. . . ]
