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 42.
Note
An Axis multicable is required when connecting external audio equipment to the Axis product. See Axis multicable on page 64.
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.

History
Object memory length.
An object that appears in
the window triggers motion
detection for a long time
before it is considered as
non-moving.
An object that appears in
the window triggers motion
detection only for a very short
time before it is considered as
non-moving.

Sensitivity
Difference in luminance
between background and
object.
Ordinary colored objects on
ordinary backgrounds trigger
motion detection.
A large difference in luminance
is required to trigger motion
detection.
Only very bright objects on
a dark background trigger
motion detection.
