Introduction
In an era where security is a top priority, CCTV camera installation has become a standard requirement for both homes and businesses. Whether you want to protect your loved ones or safeguard your commercial assets, installing a reliable CCTV system is one of the most effective ways to deter crime, monitor activity, and gain peace of mind. This ultimate guide walks you through everything you need to know about CCTV camera installation—from choosing the right system to setting it up properly.
What Is a CCTV System and How Does It Work?
A CCTV (Closed-Circuit Television) system uses video cameras to transmit a signal to a specific place for monitoring and recording. Unlike broadcast television, the signal is not openly transmitted, which means only selected users can view the footage.
Components of a Standard CCTV System:
- Cameras: Capture the video (analog or IP)
- DVR/NVR: Record and store footage (DVR for analog, NVR for IP)
- Monitor: View live or recorded footage
- Cabling or Network Setup: Connects the system components
CCTV systems are essential for ensuring visual coverage of sensitive areas and offering evidence in case of incidents.
