AXIS 240Q - Event Configuration 25

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 was opened. Check the Upload images checkbox under Event Types > Add Triggered... > Triggered by... to expand the web page with the available options.

Up to 3 MB of memory (per video source) is available for the pre-/post-trigger buffer. The maximum length of the video actually saved in the 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 internal memory in the AXIS 240Q, 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.

Scheduled Event

A Scheduled event can be activated at pre-set times, in a repeating pattern on selected weekdays.

How to set up a scheduled event

This example describes how to set the video server to send an email notification with saved images from a set time:

1.Click Add scheduled on the Event types page.

2.Enter a descriptive name for the event, e.g. Scheduled email.

3.Set the priority (High, Normal or Low).

4.Select the video source i.e. the source the event should act on, e.g. Video 2 in Storage room.

5.Set the Activation Time parameters (24h clock) when the event should be active, e.g. start on Sundays at 13.00 with a duration of 12 hours.

6.Set the When Activated... parameters, i.e. specify what the video server should do at the specified time, e.g. send uploaded images to an email address.
