DESCRIPTION  
The licence exempt X7301 CCTV Video Link consists of a compact 10mW radio transmitter and a highly  
sensitive radio receiver. Real time colour and monochrome composite video signals are presented to a BNC  
connector on the transmitter. These are then passed over a radio link to a phono connector output on the  
receiver. A range of 0.5Km to 2Km is possible in free space.  
Serial, analogue or digital camera controls signals can be transmitted back to the video transmitter via a  
licence exempt 458MHz radio link if required.  
Both the receiver and transmitter are powered from a regulated 12 volt source at 250mA.
