What is the full form of CCTV?

Introduction

Closed Circuit Television (CCTV) refers to the use of video cameras to capture and transmit signals to a limited set of monitors or screens for surveillance, security, or monitoring purposes in a specific location or area.

CCTV is used in various settings, such as homes, businesses, public spaces, and government facilities, to deter crime, monitor activity, and ensure safety and security.

How does CCTV work?

CCTV works by using video cameras to capture footage of a specific area, which is then transmitted to a set of monitors or screens for viewing and recording. Here's a detailed explanation of how CCTV works −

• Camera − CCTV cameras capture video footage of a specific area or location. These cameras can be either analog or digital and may have different features such as night vision, motion detection, or remote access.

• Transmission − The video signal from the camera is then transmitted either through a wired or wireless connection to a monitor or recording device.

• Recording − The video footage may be recorded onto a digital video recorder (DVR), a network video recorder (NVR), or onto cloud-based storage.

• Monitoring − The recorded footage or live feed from the CCTV cameras is monitored by trained personnel or security personnel.

• Playback − The recorded footage can be played back for review or analysis at a later time.
