Motion Detection Parameters
The parameters controlling motion detection are described in the table below:
Parameter
Description
High level (100%)
Medium level (50%)
Low level (0%)
Recommended values
Default values
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 34.
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 50.
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.
Object Size
Object size relative to window
size.
Only very large objects trigger
motion detection.
Even very small objects trigger
motion detection.
5–15%
15%
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.
60–90%
90%
31
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.
