This video on Copterpix Pro's APS250 Autonomous Patrolling System is a bit on the sales side, but it does highlight the system's operation and features. The small, 250-gram micro-drone is under CAA regulation specifications. The mobile 23-kg docking station has disposable drones with dual cameras (FHD day/night and thermal FLIR sensors for inspection and patrolling up to 5 km).
