What does CCTV stand for?

CCTV (closed-circuit television) is a type of video surveillance system that allows for the transmission of video from cameras to a specific place, such as a monitor or a recording device. It is called “closed-circuit” because the signal is not transmitted publicly and is only intended for viewing by a specific group of people, such as security personnel or law enforcement. CCTV systems are often used for security and surveillance purposes in public places, such as streets, buildings, and transportation systems. They can also be used in private homes and businesses for the same purpose. CCTV systems typically consist of cameras, monitors, and recording equipment. The cameras capture video footage, which is then transmitted to the monitors and/or recording equipment for viewing or storage.

How CCTV works?

CCTV (closed-circuit television) systems work by using cameras to capture video footage and transmit it to a specific place, such as a monitor or a recording device. The cameras are typically mounted in strategic locations, such as on building exteriors or in public spaces, and are connected to the monitoring and recording equipment through cables or wireless connections.

When the cameras capture video footage, the signal is transmitted to the monitoring and recording equipment, where it can be viewed in real-time or recorded for later review. Some CCTV systems also have the ability to transmit the video signal over the internet or through a network, which allows for remote viewing and management of the system.

There are many different types of CCTV cameras available, including analog cameras that transmit a continuous analog signal, and digital cameras that transmit a digital signal. There are also various types of monitoring and recording equipment, such as monitors, DVRs (digital video recorders), and NVRs (network video recorders).

Overall, CCTV systems are used for security and surveillance purposes in a variety of settings, including public places, buildings, and private homes and businesses. They can be a useful tool for deterring crime and helping to identify suspects in the event of a crime or other incident.
