IVS can be configured to generate an alert highlighting an abandoned or removed object. Suspicious objects can be detected when carried into the scene and planted by a person as well as when dropped into the scene. Ensure that abandoned/ removed object detection is enabled by checking the "Abandoned/ removed object detection" box on the event rule.
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.
An object that is left inside a zone for longer than the configured time period will trigger the rule and raise an alarm.
