CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV relies on strategic placement of cameras, and observation of the camera’s input on monitors somewhere.
CCTV systems are frequently used to make your home more secure, too. High-end, professional-grade solutions for comprehensive home surveillance can include both analog or IP-based surveillance networks (with IP-based being more popular), while lower-cost and user-friendly solutions might include smart home security cameras and devices. Again, these don’t constitute CCTV systems in the traditional sense of the word, but serve as effective, easy and low-cost solutions for keeping a watchful eye out and your home safe and secure.
