A CCTV camera, or closed-circuit television camera, is a device used for surveillance and security purposes. It captures video footage and transmits it to a specific set of monitors or recording devices, allowing for real-time observation and recording of activities in a designated area. These cameras are commonly found in public spaces, businesses, and homes to deter crime and enhance safety. CCTV cameras come in various types, including dome cameras, bullet cameras, and PTZ cameras (pan-tilt-zoom). They can be equipped with features like night vision, motion detection, and remote access, making them versatile tools for monitoring and protecting property.
