Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors.
They are a private way to monitor what is happening in and around your home. Cameras are strategically placed so you can observe certain areas of your house and property.
The cameras communicate with monitors and the images are shown only to the people who are designated to see it. This provides an optimum level of privacy and security.
