Closed-Circuit Television (CCTV), commonly referred to as video surveillance, utilizes an integrated network of cameras and recording apparatus. While a CCTV system functions autonomously, it can also be integrated seamlessly into a broader ELV framework. Such systems serve as an efficient means to oversee and safeguard critical zones. Cameras may be tethered through cables or connect wirelessly, and their mere presence is demonstrably effective in deterring potential security breaches.
