In today’s fast-changing world, security is a priority for both homes and businesses. One of the most trusted tools in the fight against theft, vandalism, and safety risks is CCTV (Closed-Circuit Television). But what is CCTV, and why is it so important in the United States?

What is CCTV?
CCTV (Closed-Circuit Television) is a video surveillance system that uses cameras to capture and transmit video signals to authorized monitors or recorders. Unlike broadcast television, CCTV is a closed system, meaning the footage is only accessible to specific users for security, monitoring, and evidence purposes.
How Does CCTV Work?
CCTV systems are straightforward:
- Cameras Capture Footage – Installed cameras record activities in real-time.
- Transmission of Signals – Footage is sent to monitors or DVR/NVR recorders.
- Storage – Video is stored on hard drives or cloud servers.
- Monitoring – Security teams or homeowners monitor live feeds.
- Playback – Recorded footage can be reviewed later for investigations.
