Product Description
This is a matched pair of DC power connectors — one male plug, one female socket — for joining or extending 12V CCTV power cables. Use it to repair a damaged connector, build a custom power lead, or extend a run to a camera that's further from the power supply than your existing cable reaches.
Both parts use the 5.5mm outer diameter / 2.1mm inner diameter DC interface, the standard size fitted to most CCTV cameras, DVRs, NVRs and 12V LED power supplies. Before ordering, check the connector size on your existing equipment matches this standard — most consumer CCTV kit does, but it's worth a quick look at the barrel connector on your camera or power adapter.
Why connection quality matters
A loose or poorly terminated DC connector is a common cause of night-time picture trouble. Infrared LEDs draw more current after dark, so a weak connection or voltage drop at the plug can cause flickering or a dropped image just when you need the camera most. These connectors use a cable mount design for secure conductor termination, which keeps electrical contact stable rather than relying on a loose crimp.
Typical uses
- Repairing a snapped or worn CCTV power connector
- Extending a power cable run to a camera
- Building a custom lead for a CCTV, DVR, NVR or LED lighting installation
Sold as a pair — one male, one female — so you can terminate both ends of a cable.

Frequently Asked Questions
What size connector is this?
It's the standard 5.5mm outer diameter, 2.1mm inner diameter DC size used on most CCTV cameras, DVRs, NVRs and 12V LED power supplies.
Do I get both the plug and the socket?
Yes, it's sold as a matched pair — one male DC plug and one female DC jack — so you can terminate both ends of a power cable.
Can this fix a camera that flickers at night?
If the flickering is caused by a loose or poorly terminated power connector, replacing it with a secure cable-mount connector like this can help; power supply rating and cable length are also worth checking.
