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.

To only detect flashing light, select a low sensitivity. In other cases high sensitivity is recommended.
