AXIS 213 - Event Configuration
Please use the online help files for descriptions of each available option.
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 has been opened. Check the
Upload images checkbox under Event Types > Add Triggered... > When Triggered...
to expand the web page with the available options.
Note: Buffer size - up to 9 MB buffer. The maximum length of time of the
pre-/post-buffer depends on the image size and selected 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 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.
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.
