AXIS P3304/-V - Events

Triggered Event

A triggered event could be activated by:

• a push button connected to the camera’s input port

•

a manually activated action, such as from an action button in the web interface

• detected movement in a configured motion detection window

• sound at a certain decibel level

• on restart (reboot), after power loss

• when the camera stops at a preset position

• camera tampering

• an application that has been uploaded to the network camera

How to set up a triggered event

The following example describes how to set u

p the camera 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 how the camera responds 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 for descriptions of each available option.

Note:

Up to 10 event types can be configured

in the camera, and up to three 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

- 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:

• 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 is reduced and individual

images may be missing. 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.
