Comment/Recommendation
Set up the camera such that no objects totally block (occlude) objects of
interest in the camera's view.
When someone walks behind something that totally blocks that person
in the camera's view, Intellex predicts where the person will be next
based on his speed when last seen.
The more a person is blocked in the camera's field of view, the more
prediction errors may occur. The Intellex can easily track a man walking
behind a tree at a constant velocity, but not a man walking behind a
building at a changing speed.
An obstruction may partially block the camera's view; for example, a
man walking behind a car may appear to be missing his lower body,
and the Intellex notices that the size of the object that it was tracking
has suddenly changed.
When you configure alarms based on the size of an object, note that
even a partial or temporary obstruction may lessen the reliability of
alarms.
If the rate drops below 7 ips, the reliability of object tracking is reduced.
Tracking quality is reduced until the Intellex unit can determine which
elements are in the background and which are moving objects.
In a busy room, place the camera up high, with a 45–90° line of sight to
the floor. If possible, aim the camera toward a motionless background.
A moving object must fit within 25% of the screen. Large objects are
common indoors. Place the camera as far away as possible from the
objects you are tracking.
Poor video feed or excessive signal boosting significantly reduce
tracking quality.
