CCTV technicians install and maintain video surveillance systems used for security monitoring, incident recording, and access control integration. They configure cameras, DVR/NVR units, network connections, and power systems while ensuring optimal coverage and compliance with safety and privacy requirements. The role demands understanding of low-voltage wiring, IP networking, digital recording technologies, and system troubleshooting. With rising global demand for security infrastructure in urban spaces, transportation hubs, industrial facilities, and commercial buildings, technicians increasingly interact with cloud-based monitoring platforms, AI-enabled analytics, and integrated security ecosystems. Precision, documentation, and adherence to installation standards are essential to ensure performance and long-term reliability.
