Plug and Play, Easy Installation
You do not need to run wires between the NVR box and cameras. Simply connect the NVR to your router with the included network cable, plug the cameras to power, and you're all set. It's convenient for you install them in any position by yourself.
pls note:
(1)If you want to remotely monitor your home or business via free app, you need network.
(2)The camera and NVR both need be powered by power supply.
