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 against Upload images under Event Types > Add Triggered... > When triggered... to expand the web page with the available options.

Buffer size - up to 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 243SA'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.

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 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.
