A modern CCTV (video surveillance) installer designs, installs and secures camera systems using IP cameras, PoE, NVR/cloud storage and analytics, while balancing coverage, budget and legal/privacy requirements.
CCTV multiplexing moved from mechanical switch boxes to software-driven systems built into NVRs, cloud services, and cameras. Modern setups record multiple streams continuously, use analytics to flag events, and support secure remote viewing.
Modern CCTV cabling includes coax, Ethernet (with PoE) and fiber, enabling higher bandwidth, digital transmission, improved interference protection, and easier integration with recorders and networks.
A modern CCTV power design combines DC supplies, PoE, UPS backup, surge protection, and remote monitoring to keep cameras online during outages and disturbances.
