Configuration of Zones and Rules

NOTE: The algorithm used for abandoned and removed object detection is the same in each
case: it cannot differentiate between abandoned or removed objects. This is a fundamental
limitation of the algorithm and arises because it just analyses how blocks of pixels change
with respect to a background model that is constructed over time. When an object is
inserted into the background (abandoned) it looks the same to the algorithm as when an
object is removed from the background.
Enable the abandoned/removed object rule on the selected zone by checking the
Abandoned/Removed Object box in the properties inspector. An object that is left inside a
zone for longer than the configured time period will trigger the rule and raise an alarm.
The following figure illustrates the abandoned/removed object detection rule detecting a
removed bicycle.
