Motion detection parameters
The parameters controlling motion detection are described in the table below:
Parameter Object Size History Sensitivity
Description Object size relative 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%
Tips:
• 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.
