Motion Detection Parameters

The parameters controlling motion detection are described in the table below:

Parameter	Object Size	History	Sensitivity
High level (100%)	Only very large objects trigger	An object that appears in	Small variations in thermal
	motion detection.	the window triggers motion	radiation between object and
		detection for a long time	background will trigger the
		before it is considered as	motion detection.
		non-moving.
Low level (0%)	Even very small objects trigger	An object that appears in	Large variations in thermal
	motion detection.	the window triggers motion	radiation between object and
		detection only for a very short	background will trigger motion
		time before it is considered as	detection
		non-moving.
Default values	Low	High	High

Note

•To trigger on small objects or movements, use several small motion detection windows rather than one large window and select a low object size.

•To avoid triggering on small objects, select a high object size.

•While monitoring an area where moving objects are not expected, select a high history level. This will cause motion detection to trigger as long as the object is present in the window.

Audio Detection

The Axis product can be configured to generate an alarm when audio rises above or falls below the threshold value. The threshold value can be set in the range 0–100 where 0 is the most sensitive and 100 the least sensitive.

1.Go to Detectors > Audio Detection.

2.Set the audio alarm level and click Save.

3.Go to Events > Action Rules and set up an action rule, see Setting Up an Action Rule, on page 30.

Note

A multi-connector cable (available from Axis) is required when connecting external audio equipment to the Axis product. See Multi-Connector Cable (sold separately), on page 47.

Detected audio is indicated by colored peaks in the Activity indicator. An event is triggered when detected audio rises above or falls below the threshold value, which is represented by the bar.
