AXIS 210/210A/211/211A - Event Configuration Pre-trigger and Post-trigger buffers This function is very useful when checking to see what happened immediately before and/or after a trigger, e. g. Check the Upload images checkbox under Event Types > Add Triggered. . . 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. Notes: ·Pre-trigger and Post-trigger buffers will be lost if the connection to the event server fails. ·The maximum length of the pre-/post-buffer depends on the video image size and selected frame rate. ·If the pre- or post-buffer is too large for the camera'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. 35 Continue image upload (unbuffered) - enables the upload of video 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 preset times, in a repeating pattern on selected weekdays. Set the Activation Time parameters (24h clock) when the event will be active, e. g. Please see the online help for descriptions of each available option. 36 AXIS 210/210A/211/211A - Event Configuration Motion Detection Motion detection is used to generate an alarm whenever movement occurs (or stops) in the video image. · Included windows target specific areas within the whole video image · Excluded windows define areas within an Include window that should be ignored (areas outside Include windows are automatically ignored) Once configured, the motion detection windows will appear in the list of available triggers, for triggering events. Note: Using the motion detection feature may decrease the camera's overall performance. Configuring Motion Detection 1. Adjust the size (drag the bottom right-hand corner) and position (click on the text at the top and drag to the desired position). 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). Click Save. To exclude parts of the Include window, click the Configure Excluded Windows button and position the Exclude window as required, within the Include window. AXIS 210/210A/211/211A - Event Configuration Please see the online help Object Size High level Only very large objects trigger motion detection Even very small objects trigger motion detection Low 37 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 Sensitivity Ordinary colored objects on ordinary backgrounds will trigger the motion detection Only very bright objects on a dark background will trigger motion detection Medium to High Low level Default value Examples: · · · Avoid triggering on small objects in the video image by setting the object size level to high. To reduce the number of triggers if there is a lot of movement during a short period of time, select a high history level.
