CCTV power supplies in Kenya

A stable CCTV power supply keeps cameras recording day and night. This collection lists 12V DC supplies in 5A, 10A, 20A and 30A ratings, in open and closed versions, for powering analogue and other 12V cameras from one central unit. These are the sizes people search for as a 12V 30A power supply or a 12V 10A CCTV power supply.

How to size the supply

Add up the maximum current of every camera. Use the camera's rated maximum, because infrared LEDs, heaters and motorised lenses draw more when active. Add a safety margin of 20 to 30 percent. Eight cameras at 1A need 8A, so a 10A supply is a sensible choice. Power is volts multiplied by amps, so a 12V 10A unit is rated for 120W.

Voltage drop on the cable

Current flows out to the camera and back, so long, thin cable loses voltage. CCTV guides use a 10 percent limit, meaning a 12V camera should still receive at least about 10.8V. As an example, a camera drawing 300mA on 18AWG cable can run to about 289 feet (88 metres) before reaching that limit. Heavier cable, a shorter run or a supply placed nearer the camera fixes under-voltage. Measure with a multimeter after installing. See alarm cables for multi-core cable.

Open or closed

Type What it means Good for
Open (open frame) An exposed board with no full case; runs cooler, smaller and cheaper, but live parts can shock if touched Mounting inside a cabinet or enclosure
Closed (enclosed) Protective case that shields the electronics from dust and accidental contact Standalone mounting on a wall or shelf

Open units must go in a dry, safe enclosure with good airflow and should not be opened while powered.

Choosing a rating

  • 5A: a few cameras.
  • 10A: a typical 4 to 8 camera home or shop system.
  • 20A and 30A: larger systems, or those with infrared and other 12V loads.

Available power supplies

Add a UPS so cameras keep running during outages.

Frequently asked questions

Can I use a 30A supply on a small system?

Yes, a larger rating just gives spare capacity, if the voltage is 12V.

Why do cameras flicker at night?

Weak power or long thin cable is common, as infrared draws more current.

Can one supply power a DVR?

Most DVRs have their own adapter; check the DVR before sharing.
