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

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.
