Each camera has its main activity detector. By default, camera arming/disarming means the main activity detector is switched on/off. An alarm event by the main detector takes place (and is registered by the system), when motion within the observed scene begins. If a camera is disarmed, the alarm event is not registered.

Main and auxiliary detection zones can be masked. Mask is the scene image area with no scene control (for example, if you mask the detector main zone, there is no scene control in progress inside the mask).
