Motion Detection Parameters
The parameters controlling motion detectio n are described in the table below:
Parameter
Object Size
History
Sensitivity
Description
Object size r ela tive to window
size.
Object memory length.
Difference in luminance
between background and
object.
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.
Ordinary colored objects on
ordinary backgrounds trigger
motion detection.
Medium level (50%)
A large difference in luminance
is required to trigger 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.
Only very bright objects on
a dark background trigger
motion detection.
Recommended values
5–15% 60–90% 75–95%
Default values
15% 90% 90%
Note
• To trigger on small objects or movements, use several small motion detection windows rather than o ne 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 D etection
The Axis p roduct 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 A ction 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 ev ent is triggered whe n detected audio rises above or fa lls
below the threshold value, w hich is represented by the bar.
