  • Waterproof and adjustable frequency for avoiding the frequency interference
  • Bandwidth (2.29-2.51GHz) with the widely adjust range.
  • The traditional connector is transparent (BNC, AV), signal input AV.
  • Power: AC 100-240V or DC12V available according customers requested to meet the solar or battery powered devices.


If there is obstruction, we should be try the best to avoid them.

Firstly, extend the video cable to place the TX and RX higher then obstruction. If cannot this way, find a repeater where can see each other point.




Equipment is suitable place: Building Ground, Orefield, mountain region, stride over river, large factories, large building ground, Military exercise areas, large parking lots, Oil collection point, etc. Please make sure the NLOS environment between TX and RX. The main obstruction included: Building, mountain, tree (Don't ignore the tree as obstruction)
