How CCTV Works

A traditional CCTV system operates through an analog signal, meaning the camera captures video and sends the footage via a coaxial cable to a digital video recorder (DVR). The DVR then processes and stores the video, which can be accessed through monitors or remote systems.

CCTV cameras typically capture video in real-time and record it to a storage device, allowing for playback in the event of an incident. The cameras themselves are usually mounted in strategic locations to cover key areas such as entry points, hallways, and parking lots. Depending on the system’s complexity, some CCTV setups may also include features like motion detection, remote viewing, and video analytics.

Components of a CCTV System

A basic CCTV system consists of several key components:

Cameras: These are the eyes of the system, capturing footage in real-time. Cameras can vary in quality, ranging from basic models with low resolution to high-definition cameras that provide clear and sharp images.
Monitor/Display: The monitor is where live footage or recorded video is displayed. In smaller systems, it may be a single monitor connected to a DVR, while larger setups may include multiple displays for broader surveillance coverage.
DVR (Digital Video Recorder): The DVR records video footage captured by the cameras. It stores the footage for later review and can be programmed to overwrite old footage after a set period, depending on storage space.
Cables and Connectors: In a traditional CCTV setup, coaxial cables connect the cameras to the DVR and monitor. The quality and length of the cables can impact the signal transmission and video quality.
Power Supply: CCTV systems require a reliable power supply to operate continuously. Cameras and other components may be connected to a central power source or individual adapters.
