Triggered Events

AXIS 209FD/FD-R/FD-R M12 21

A Triggered event can be activated by:

•a manual trigger from an action button in the web interface, or by a trigger sent via the VAPIX® API

•detected movement in a configured motion detection window

•on restart (boot) after e.g. power loss

•a temperature alarm

•a camera tampering alarm (AXIS 209 FD-R/FD-R M12)

How to set up a triggered event

This example describes how to set up the camera to upload images when e.g there is movement in the image:

1.Click Add triggered on the Event types page.

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

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

4.Set the Respond to Trigger... parameters for when the event will be active, e.g. only after office hours.

5.Select the trigger alternative from the Triggered by... drop-down list, i.e. select Motion detection. Also select the required window and if the alarm should be triggered when motion starts or stops.

6.Set the When Triggered... parameters, i.e. define what the camera will do if there is an alarm, e.g. upload images to an FTP server or send an e-mail notification.

7.Click OK to save the Event in the Event Types list.

Please see the online help for descriptions of each available option.

Note: Up to 10 event types can be configured in the camera, and up to 3 of these can be configured to upload images. Files names can be formatted according to specific requirements. See File Naming & Date/Time Formats online help.

Pre-trigger and Post-trigger buffers

This function is very useful when checking to see what happened immediately before and/or after a trigger, e.g. 30 seconds before and/or after the event. Check the Upload images checkbox under Event Types > Add Triggered... > Triggered by... to expand the web page with the available options. All uploaded images are JPEG images.

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: •Pre-trigger and Post-trigger buffers will be lost if the connection to the event server fails.

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

•If the pre- or post-buffer is too large for the camera’s 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) - enables the upload of video 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.
