> Video motion detection: When a camera detects certain movement in a camera's motion
detection window, an event can be triggered. For more on video motion detection see page
102.
> Camera tampering: This feature, which allows a camera to detect when it has been
intentionally covered, moved or is no longer in focus, can be used to trigger an event. For
more on active tampering alarm, see page 102.
> Audio trigger: This enables a camera with built-in audio support to trigger an event if it
detects audio below or above a certain threshold. For more on audio detection, see Chapter 8.

event can be triggered.

Responses
Network video products or a video management software program can be configured to respond
to events all the time or at certain set times. When an event is triggered, some of the common
responses that can be configured include the following:
> Upload images or recording of video streams to specified location(s) and at a certain frame
rate. When using the event-triggered functionality in Axis network video products' web
interface, only JPEG images can be uploaded. When using a video management software
program, a video stream with a specified compression format (H.264/MPEG-4/Motion JPEG) and
compression level can be requested from the network video product.
