FACILITY SURVEILLANCE SYSTEMS AND METHODS

The invention pertains to a mobile surveillance system (200) adapted for patrolling a surveillance area of a facility like a building, the system comprising a plurality of sensors and at least one unmanned ground vehicle (UGV; 210) that is adapted to move autonomously on a ground of the surveillance area, the UGV (210) comprising a housing (211) enclosing- a first battery (217);- first sensor means, particularly comprising a first camera (213), the first sensor means being adapted to generate first sensor data,- a first computing unit (218) comprising a processor and a data storage, the first computing unit (218) being adapted to receive and evaluate the first sensor data in real time.According to the invention, the system (200) further comprises at least one unmanned aerial vehicle (UAV; 220), the UGV (210) and the UAV (220) being adapted for collaboratively patrolling the surveillance area, in particular autonomously, wherein- the UAV (220) comprises second sensor means (223), particularly comprising a second camera (223), the second sensor means being adapted to generate second sensor data (252),- the UGV (210) comprises a first data exchange module (215) and the UAV (220) comprises a second data exchange module (225), the first and second data exchange modules (215, 225) being adapted to exchange data (251, 252); and- the first computing unit (218) is adapted to receive and evaluate the second sensor data (252) in real time.
