CCTV Power Supplies

A CCTV power supply turns mains into the low voltage a camera runs on, whether through a plug-in adapter for one camera or a boxed unit feeding a whole system. The range includes Haydon, Folk Safe and ESP 12V DC supplies in inline, plug-top and boxed forms, 24V DC and 24 VAC boxed units, battery-backed PSUs and DC splitters, plus a Hikvision PoE midspan and solar kit and an EZVIZ doorbell transformer.

Choosing CCTV Power Supplies

Match the supply to the camera's voltage first, then add up the current the cameras draw and leave headroom.

Matching the voltage

Most of the supplies here give 12V DC, the usual input for analogue and many IP cameras. The Haydon HAY-PSU4/1-1/4A24, HAY-PSU4/2-2/4A24 and HAY-PSU8/1-1/8A24 give 24 VAC for cameras rated for it, the HAY-PSUINLINE3A24 is a 24 VAC inline supply at 3A, and the HAY-48V2.5A gives 48V DC for PoE NVRs and PoC DVRs.

Inline, plug-top or boxed

Inline and plug-top adapters power one camera from a nearby socket: the Folk Safe FS-12D1000-A plug-top gives 12V 1A through a 2.1mm barrel, and the Haydon HAY-PSUINLINE5A gives 12V 5A. Multi-output supplies such as the Haydon HAY-PSUMULTI10A, with 16 outputs sharing 10A, and the ESP CPS18W, with 18 ways at 10A, feed several cameras. The Haydon DC04 and Folk Safe FS-DC1F4M splitters share one adapter between four cameras.

Battery backup

A battery-backed PSU charges a standby battery and switches to it when the mains fails, so cameras and recorders keep running. Haydon boxed units such as the HAY-PSU12V3ABB take a 7Ah lead acid battery, the HAY-DC24V5ABBLPSU adds a mains-fail relay and tamper detection, and the Folk Safe FS-DC120805B and FS-DC121820B pair a battery backup option with 8 and 18 outputs.

Off-grid and doorbell power

The Hikvision DS-2XS6K01-C36S80 solar kit pairs an 80W panel with a 360Wh lithium battery and gives 9–12.6V DC for cameras where there is no mains, and the EZVIZ CS-TRANSFORMER BT16 is a DIN-rail transformer giving 8, 12 or 24 V AC for an EZVIZ doorbell.

Frequently asked questions

How do you connect a CCTV power supply?

Connect the camera's DC lead to the supply output, matching positive to positive, and switch on the mains last. Plug-in adapters usually join the camera with a barrel plug, while boxed supplies are wired into screw terminals. Check the voltage and polarity before powering up, and keep the total camera current within the supply rating. The range here includes plug-top, inline and boxed supplies.

What is a CCTV power supply?

A CCTV power supply converts mains electricity into the low-voltage DC or AC that security cameras and recorders need. Many cameras typically run on 12V DC, while some PTZ cameras use 24V AC. Pick a supply rated above the combined camera current, with battery backup where recording must continue in a power cut. The range here includes battery-backed boxed supplies and DC splitter leads.
