This system consists of 2 pcbs a driver and a receiver. The cctv camera is connected to the driver. The driver converts the single sided analogue video signal into a differential signal that is sent over a twisted pair in the standard (and cheap) Cat5 or 6 cable. Another pair can be used for the 12V power that drives the camera and the driver. At the other end the receiver converts, filters and boosts the analogue video signal ready for the monitor. Both the driver and receiver use the LT6552 video difference amplifier chips.
The driver and receiver are supplied as fully tested populated PCBs ready for you to mount into your housing.
The video driver is 39.25 x 30mm it runs on a nominal 12V but will run down to 7V
The receiver is 43.3 x 30mm it runs on a nominal 12V but will run down to 7V
