Security system

A security system for use in a vehicle, comprising:

• a first device configured for mounting in a first location of a vehicle;
• a second device configured for mounting in a second location of a vehicle different from the first location;
• wherein, the first device comprises:
• a first image capture module facing a first direction;
• a first object detection module operative to detect the presence of an object exterior to a vehicle in which the first device may be mounted;
• the second device comprises:
• a second image capture module facing a second direction, the second direction different from the first direction;
• a second object detection module operative to detect the presence of an object exterior to a vehicle in which the first and second device may be mounted;
• wherein, the first device and the second device are configured to couple to each other to communicate data captured on the second device to the first device;
• and
• the first object detection module and the second object detection module in combination are disposed to provide object detection within a perimeter security region of a vehicle in which the first and second device is mounted,
• wherein the first object detection module comprises a first signal transmitter and a second signal transmitter, the first and second signal transmitters being operative to emit an object ranging signal, and
• wherein the first signal transmitter is oriented so that the direction of the transmitted signal is at a first angle relative to a central focal line of the field of view of the first image capture module and the second signal transmitter is oriented so that the direction of the transmitted signal is at a second angle relative to the central focal line of the field of view of the first image capture module.
