| 2.4-2.8GHZ CCTV RADIO VIDEO LINK FEATURES TX7303 RX7303 * * * * * * * * * * Real time video radio transmitter and receiver PAL colour or monochrome CCTV Four Channels 1V pk - pk 75 video Signal Pan & Tilt or RS232 / RS485 Control System (option) ETSI 300-400-1 Licence exempt Range 0.5 km - 2 km Line of Sight 2.4Hz - 2.8 GHz FM modulation Compact size 12V DC supply 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.
