How To Set Up A Triggered Event - Axis Q7401 User Manual

Triggered Event
A triggered event could be activated by:
• a push button connected to the video encoder's input port
• a manually activated action, such as from an action button in the web interface
• an application that has been uploaded to the video encoder.
• detected movement in a configured motion detection window
• on restart (reboot), after power loss
• camera tampering
• disk full
• video loss
• sound at a certain decibel level

How to set up a triggered event

The following example describes how to set up the video encoder to upload images when the main door is opened.
1. Click Add triggered... on the Event Types page. The Triggered Event Type Setup page appears.
2. Enter a descriptive Name for the event, such as Main door open.
3. Set the Priority - High, Normal or Low (see the online help).
4. Set the Respond to Trigger... parameters to define when the event is active, for example, after office hours.
5. Select the trigger alternative from the Triggered by... drop-down list. For example, select Input ports, for a sensor
connected to the door.
6. Set the When Triggered... parameters, that is, define what the video encoder will do if the main door is opened -
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
Notes:
• Up to 10 event types can be configured in the video encoder, and up to four of these can be configured to upload
images.
• File 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, for example, 30
seconds before and/or after a door was opened. Check the Save stream checkbox under Event Types > Add Triggered... >
When Triggered... to view the options. All uploaded images are JPEG images.
Include pre-trigger buffer - contains images 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 video encoder's internal memory, the buffer size is reduced so that
the recorded time is less than expected. If this occurs, an entry is 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.
