Claim 35:
36. A vehicular vision system, said vehicular vision system comprising:
an internal cabin surveillance camera disposed at a vehicle equipped with said vehicular vision system, said internal cabin surveillance camera viewing interior of the equipped vehicle;
said internal cabin surveillance camera comprising a CMOS imaging sensor operable to capture image data;
an electronic control unit (ECU) disposed at the vehicle and comprising (i) a data processor and (ii) a DC power supply;
wherein image data captured by the CMOS imaging sensor of said internal cabin surveillance camera is conveyed from said internal cabin surveillance camera to the ECU via a single core coaxial cable;
wherein said internal cabin surveillance camera is in bidirectional communication with the ECU over the single core coaxial cable;
wherein the single core coaxial cable commonly carries (i) image data captured by the CMOS imaging sensor of said internal cabin surveillance camera to the ECU for processing at the data processor of the ECU and (ii) power from the DC power supply of the ECU to said internal cabin surveillance camera;
wherein image data captured by the CMOS imaging sensor of said internal cabin surveillance camera is transmitted via the single core coaxial cable at a data transmission rate of at least 1.6 Gbps;
wherein power carried by the single core coaxial cable from the DC power supply of the ECU to said internal cabin surveillance camera is at an electrical current less than or equal to 900 mA;
wherein said internal cabin surveillance camera comprises a data serializer and the ECU comprises a data deserializer, and wherein image data captured by the CMOS imaging sensor is serialized at the data serializer and is conveyed to the ECU via the single core coaxial cable and is deserialized at the ECU by the data deserializer; and
wherein, responsive to processing at the ECU of image data captured by said internal cabin surveillance camera and conveyed to the ECU via the single core coaxial cable, an object present interior of the equipped vehicle is detected.
