Infrared and charged coupled device video camera data communications system.<BR> Data 1 is transmitted in the infra red range of the electromagnetic spectrum,<BR> This light 3 is picked up by a video camera 11 which consists of a lens 6, CCD chip 7, video circuitry 8 and outputs a video signal 22 whereupon a decoder 9 is used to retrieve the original data 1. The transmitter may alternatively comprise a laser or halogen lamp. Both transmitter and receiver may include matched wavelength filters.
