Independent Intelligence: The panorama camera and the detail camera can run different types of intelligent functions.
Panorama (only one function can be enabled at a time): Perimeter protection and video metadata (takes snapshots and recognizes the attributes of motor vehicles, non-motor vehicles and people).
Detail (only one function can be enabled at a time): Face recognition, perimeter protection and video metadata (takes snapshots and recognizes the attributes of motor vehicles, non-motor vehicles and people).
Linked Intelligence:
For perimeter protection, the panoramic camera links with the detail camera to track targets.
