It's an awesome product developed by Jeatone
It can trans digital data wireless.
This kit production consists of transmitter part and receiver part,just like a cable between transmitter and receiver.

Yes it seems not cool,it's just a "wireless cable"...
But it can trans signal over 1000M

You can even install a solar camera on your farm,while the NVR is still in your house.
With its waterproof design , it don't afraid of rain，which can make you install your camera very far (but it cannot prevent flooding)
