Motion Detection Parameters

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

Parameter	Object Size	History	Sensitivity
Description	Object size relative to window	Object memory length.	Difference in luminance
	size.		between background and
			object.
High level (100%)	Only very large objects trigger	An object that appears in	Ordinary colored objects on
	motion detection.	the window triggers motion	ordinary backgrounds trigger
		detection for a long time	motion detection.
		before it is considered as
		non-moving.
Medium level (50%)			A large difference in luminance
			is required to trigger motion
			detection.
Low level (0%)	Even very small objects trigger	An object that appears in	Only very bright objects on
	motion detection.	the window triggers motion	a dark background trigger
		detection only for a very short	motion detection.
		time before it is considered as
		non-moving.
Recommended values	5–15%	60–90%	75–95%
Default values	15%	90%	90%

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.

•To only detect flashing light, select a low sensitivity. In other cases high sensitivity is recommended.

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 Set Up Action Rules on page 36.

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.
