    CCTV, or closed-circuit television, is a system that allows you to keep an eye on what’s going on in and around your business. Cameras and monitors enable you to view events live, and recorders archive footage for later reference. Don’t mistake a CCTV monitor for an ordinary television. It doesn’t receive publicly broadcasted content—only footage from security cameras installed on the premises.

    CCTV technology has been around for decades, but improvements in recent years make it even more effective at capturing criminals in the act and bringing them to justice. Consider the various parts of a CCTV system and how they all work together.

    Just like a camcorder. It receives light via a lens. That light strikes a sensor which produces data. That data is translated into an actual image and then transmitted via a wire or WiFi to a device used to view said photo.

    A full explanation would take a good number of pages in a book.

    I suggest finding a published article on the subject.

      The camera works the same as any other camera which provides moving images. What you really want to know is how those images are stored, and who has access to them, and how long they are stored, and matters of that sort. That varies from place to place.

    Closed Circuit TeleVision.

    You set up a TV channel for viewing only in a small specific area. What you need is a camera to capture what is happening and a monitor to view what the camera can see. Usually, you place the two in different parts of a building like the camera at the main entrance and the monitor inside a room. Since both camera and monitor are dumb devices (in a technical point of view), you need something in between to translate the camera's signals so that the monitor can understand it. This something may be a VCR or a computer.

    CCTV stands for "closed circuit television", as opposed to "broadcast television". The traditional method has been to run coaxial cable from each camera to a single location where the cameras can be monitored and/or recorded, such as a business's security office. Now a lot of CCTV systems use internet-style networking to stream the camera's video to the monitoring system, but the result is the same.
