Multi-channel CCTV power supply units consolidate the 12V DC power distribution for all cameras in a system into a single managed unit at the DVR location. Rather than running individual camera power supplies or using multiple smaller PSUs, an 18-way unit provides terminated individual outputs for up to 18 cameras, each individually fused to protect against overload at a single camera position without taking down the entire system.
At 20 amps total output, the unit can supply the load of 18 standard HD cameras comfortably, with headroom for cameras that draw slightly more current at startup than during continuous operation. Individual terminals for each channel allow cameras to be wired cleanly and labelled, making fault-finding and maintenance straightforward compared to a less organised power arrangement.
The lockable boxed enclosure is a security feature: camera power wiring is the most vulnerable part of an analogue CCTV infrastructure because cutting the power to cameras silences the system without triggering any alarm. A locked enclosure at the DVR position adds a physical layer of protection against deliberate interference with the power distribution.
For CCTV installation engineers completing analogue camera systems across large commercial and industrial sites in London and the UK, the 18-way 20A boxed PSU provides a professional, organised, and secure power distribution solution at the recorder position.
