Welcome to FPV world. This unit will allow you to put camera on your plane/multi-rotor and watch on ground. This package contain 5.8GHz 200W Transmitter and 5.8GHz 8CH receiver.
Specification of this 5.8GHz claim that you can fly away around 1-2km. But after tested with real flight, I can get only 800m and signal seem not good. The range can be extend by purchase extra patch antenna like 5.8GHz 12dbi patch antenna.
Setup for using this tx/rx is so easy. Only correct dipped switch on both side to be same and watch. It not have any correction method or algorithm. Please see diagram below.
