CCTV System

Description

The term “CCTV system” refers to a Closed-Circuit Television system. Here’s a breakdown of what that means:

• Closed-Circuit Television (CCTV)
  • Closed-Circuit
    This is the key differentiator. It means the video feed from the cameras is transmitted to a limited number of monitors and/or recording devices. Unlike broadcast television, the signal is not publicly distributed. It’s a private system.
  • Television
    This refers to the use of video cameras to transmit signals to screens.

In essence, a CCTV system is a video surveillance system that uses cameras to monitor and record activity in a specific area.

    • Analog Cameras
      Transmit video signals over coaxial cables.
    • Infrared (IR) Cameras

    • Weatherproof Cameras
      Designed to withstand outdoor elements.
