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 Setting Up an Action Rule, on page 34.

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.
