AXIS 241Q/241S - 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, for example, two minutes before and after a door was opened. Check the
box Upload images under Event Types > Add Triggered... > When triggered... to view the
available options.
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.
Notes:
• If the pre- or post-buffer is too large for the video server’s internal memory, the frame rate is reduced
and individual images may be missing. If this occurs, an entry will be created in the unit's log file.
• The images in pre-trigger and post-trigger buffers will be lost if the connection to the event server
fails.
Continue image upload (unbuffered) - enables 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 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.
