The AV-500AHD-MINI kit is designed for transmission of high resolution image in AHD-M / AHD-L / PAL standard. A both devices have built-in the antennas, which enable good quality transmission up to 500m distance and can operate on the one of the 8 available frequency channels.
To correct operation, the transmitter and the receiver should be visible to each other and have set the same channel configuration (the same channel switchers settings).
The device has a differential (symmetrical) input / output, which allows to signal transmission via twisted-pair cable and also an asymmetrical input / output to signal transmission via coaxial cable.
