CCTV (Closed-Circuit Television) Camera

Closed-Circuit Television (CCTV) refers to a system where the video signal is transmitted to a specific, limited set of monitors rather than being publicly broadcast. The technology originated in Germany in 1942 for monitoring V-2 rocket launches and was later commercialized in the United States in 1949. Today, it is a cornerstone of global security infrastructure used by governments, businesses, and homeowners alike.

Manufacturing of CCTV components is predominantly concentrated in China, which hosts some of the world's largest surveillance manufacturers, though high-end specialized components are also produced in South Korea, Germany, Japan, and the United States. The sector has evolved from simple analog systems to sophisticated Internet Protocol (IP) cameras featuring artificial intelligence, facial recognition, and cloud integration.

The global market is led by major technology conglomerates. While many localized brands exist, the industry is largely shaped by a few dominant players that provide the underlying hardware and software ecosystems used worldwide for public safety and private asset protection.
