Network CCTV System

Twisted-pair cable communication (RJ45)

The network CCTV system is the most common type of video surveillance system, which uses IP cameras to transmit video via Ethernet. A network video recorder (NVR) stores the video and controls the cameras.

IP explosion-proof cameras are required for CCTV projects in hazardous environments, such as LNG facilities, to ensure that the cameras themselves do not pose any additional risk to the site.

FAQs

IP CCTV systems in hazardous areas typically use shielded twisted-pair cables (CAT5e/CAT6) with RJ45 connectors. For long-distance transmission or extreme interference, fiber optic cables with SC/APC connectors are recommended.
No, standard NVRs must be installed in a safe area (non-hazardous zone). Only the cameras and junction boxes at the front end need to be ATEX/IECEx certified explosion-proof equipment.
A typical BOM includes: IP Explosion-proof Cameras, Explosion-proof Junction Boxes for cable routing, Shielded Twisted-pair Cables (CAT6), PoE Switches (in safe area or certified), and NVRs with VMS software.
