Transmission balun for analog surveillance camera by two wire

The BALP is a pair of 2 wire /BNC balun for connecting analog surveillance cameras reusing 2 wire cabling (Hi-Fi, power, ...) an unsatisfactory video surveillance system.
The economic interest is twofold:
Financial by dispensing the purchase and installation of a new cable network.
Time limiting the deployment time for the new video surveillance solution.

The BALP is compatible with our analog surveillance cameras (excluding HD-SDI) and transmits the video signal.
