The wiring of the traditional surveillance camera is transformed into a wireless camera.

Yes, the cable doesn't need to be moved now, because the wireless camera also uses DC 12v power adapter, which can be used universally. But you have to install a wireless router to transmit the wireless video signal to the video recorder, and the video recorder has to become NvR (Digital Video Recorder) to transmit the video signal of the wireless router to NvR through the network cable. (Note that the gate should not be too far away from the wireless router. )
