The installation of a home security system is going to vary based on the type and the complexity. In most cases, with the CCTV systems, one would run the wires and attach them to the cameras that you mount in different locations on your property. A trick to making sure that you have the best coverage is to hook up the camera before mounting. Have one person outside moving the camera until it is in the right position, and the other looking at the monitor to ensure the best angle. You can then simply mount the camera and work with your software or system to set up your surveillance protocols.
