A CCTV camera is a type of video surveillance camera that is used to transmit a signal to a specific, limited set of monitors.

CCTV cameras are commonly used in a variety of settings, such as homes, businesses, and public spaces, to provide security and surveillance. 

They can be connected to a digital video recorder (DVR) or to a network, allowing the footage to be recorded and/or viewed remotely. There are many types of CCTV cameras available, including analog, IP, and wireless cameras, each with their own unique features and capabilities.
