Abstract
A vehicle imaging surveillance and recording system adapted to monitor conditions prevailing during the course of a trip and provided for this purpose cameras are placed in the control station of the vehicle and about the vehicle. At least two recording devices record the output of the cameras. One device records a thirty minute high resolution image. The second device records a two hour lower resolution image. Both devices compress the data that is to be recorded in storage. The output signals yielded from storage are fed into an on-board transmitter to modulate a carrier that is radiated from the vehicle and intercepted by an active communications satellite. These output signals are being transmitted only under certain conditions. One condition is to provide a switch under the control of a crew member in the control station of the vehicle. The other condition provides for automatically switching on the transmission to the satellite when certain parameters occur.
