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.

•If no objects should appear in the Include Window, 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 33.

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.

PIR Sensor

The PIR (Passive Infrared) sensor detects motion by measuring changes in infrared light. The sensor can for example be used in low-light environments where video motion detection (see page 29) is not reliable.

To adjust the sensitivity of the PIR sensor, an action rule that activates the built-in light when the PIR sensor detects motion is useful:

1.Go to Events > Action Rules and click Add.

2.Select Detectors from the Trigger list and then select PIR.

3.Select Activate Light as the action.

4.Click OK to save the rule.

5.Go to Detectors > PIR Sensor.

6.Make sure there is movement in front of the camera and adjust the Sensitivity until the light is activated.

7.When satisfied, click Save.

By setting up action rules, the Axis product can be configured to, for example, record video when the PIR sensor detects motion. If the camera is used in a low-light environment, an action rule that turns on the built-in light can improve image quality of the recorded video.

For more information on action rules, see Events, on page 32.
