Our cctv system has only 3 cameras because that was the practical points in our home. But to see a blank as the 4th part of the cctv screen we decided to add another camera. That will have 4 cameras which would give 4 video shots on the cctv screen which is divided into 4 sectors.
Now we can see the porch if there is an intruder likewise with the backyard and also by the side of our house. The main camera is in the living room which clearly shows what is happening. What’s good with the cctv is that we can see the videos even if we are away.
Do you trust your cctv system?
