AXIS 243Q Blade - Event configuration 33

Triggered Event

A triggered event is activated by one of the following:

•a signal on an input port, from a connected push button

•detected movement in a configured motion detection window

•when the video signal is lost

•a manual action, such as, clicking the trigger button in the web interface

•on restart (reboot) after power loss

•a camera tampering alarm

•pan/tilt/zoom

How to set up a triggered event

This example describes how to set the AXIS 243Q Blade to upload images when a door is opened:

1.Click Add triggered... on the Event Types page.

2.Enter a descriptive name for the event, such as, Main door.

3.Set the priority - High, Normal or Low (see the online help).

4.Enter the minimum time interval between triggers.

5.Set the Respond to Trigger... parameters, to define when the event is to be active, for example, only after office hours

6.Select the trigger alternative from the Triggered by... drop-down list, for example, an input port with a connected sensor if the door is opened.

7.Set the When Triggered... parameters, that is, what the video server should do if the door is opened - upload images to an FTP server.

8.Click OK to save the event in the Event Types list.

Please see the online help 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, for example, two minutes before and after a door is opened. Check the Upload images checkbox under Event Types > Add Triggered... > When triggered... to expand the web page with the available options.

The maximum length of time of the pre-/post-buffer depends on the selected image size and frame rate.

The Include pre-trigger buffer option refers to images stored in the server from just before the trigger. Check this option to enable the pre-trigger buffer, enter the desired length of time, and specify the required image frequency.
