Vehicle mounted articulating camera
An articulatable mount for temporarily affixing a camera and illumination system to a vehicle is disclosed. The articulating drive mechanism is lightweight, vertically compact, and ruggedized for severe service such as withstanding shocks from off-road travel and abrupt maneuvering. Articulation and illumination may be controlled remotely over Wi-Fi from inside or nearby the vehicle, and encrypted video feeds may be received by authorized users of an ad-hoc network of available smart-phone users and in-vehicle computer systems authorized and authenticated to participate in the network.
