It seems that the most difficult part of CCTV installation is to run security camera wires and cables.
Before you get started, you should plan the security camera wire route in the preparation phase, especially when you plan to install cameras in multiple spots, such as, in hallways, basement, garage, through the attic, under the eave, in ceiling soffit.
Drill holes where the wires will go through, and consider the nearest route if you are doing the installation in a two or three-story house. Push all of the ends of the camera cables on the holes you have drilled. This way, you can conceal the wires and prevent them from wearing out. You can also choose a room wherein you want all your cables to be placed.
Each of the cable wires also consists of two wires with their connectors. One of the wires is intended for the good power supply. The other one is also intended for the video recorder. For the power supply, you can either create a single power source for the wires or plug each of them on different sockets. Once the wires for view recording have been connected to the DVR/NVR recorder, it will now be connected to the monitor. This is where you can see all of the images captured by the cameras.
