The surveillance market refers to the global industry involved in the development, sale, and distribution of technologies and tools designed to monitor, track, and analyze individuals’ digital and physical activities. This market includes products such as CCTV cameras, spyware, facial recognition systems, and software for intercepting communications. Governments, corporations, and private entities use these tools for security, law enforcement, intelligence gathering, and sometimes for commercial or personal purposes. The growth of the surveillance market raises important questions about privacy, ethics, and regulatory oversight.
