A first housing houses the receiver and the display device to form a self-contained, viable receiver unit. A camera captures at least one image. A transmitter transmits a signal based upon the at least one image captured by the camera. A second housing houses the camera and the transmitter to from a self-contained, viable transmitter unit.
