Surveillance cameras 4 cameras with receiver I have four surveillance cameras with a special receiver for the cameras. The cameras are without wiring, just plug them in, and they are connected remotely to the receiver. If guests come, for privacy, you can unplug the cable, and it won't be damaged. Just plug it back in, and it will work again. They are without sound, but they have the feature of recording and reviewing recordings by date and time. And in the dark, clear vision. Only one cable needs to be connected to the receiver to your internet. The cameras are excellent, and you can monitor them while you are away from home. Whoever knows someone who wants them, I will sell them for 200 or only 1800 for serious buyers, and say the last price for those who are from my side only. Whoever knows someone who wants them, inform me. Because she is moving out of her apartment and told me to ask.
