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
motion detection.
An object that appears in
the window triggers motion
detection for a long time
before it is considered as
non-moving.
Small variations in thermal
radiation between object and
background will trigger the
motion detection.
Low level (0%)
Even very small objects trigger
motion detection.
An object that appears in
the window triggers motion
detection only for a very short
time before it is considered as
non-moving.
Large variations in thermal
radiation between object and
background will trigger motion
detection
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 congured 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.
