Product Description
A 12V DC power connector snapping on site is one of the more annoying small faults in CCTV work — this pair fixes that without a full re-terminate.
You get one DC 2.1mm male plug and one matching female jack, sized to 5.5mm outer diameter / 2.1mm inner diameter — the standard barrel size used on most CCTV cameras, DVRs and NVRs. If your existing power lead uses that fitting (check the camera or PSU spec first), this will match it.
What it's actually for
- Repairing a damaged or crushed power connector without replacing the whole cable run
- Extending a power cable when a camera gets repositioned further from its supply
- Building your own leads from bulk cable when pre-made ones aren't the right length
- General 12V DC low-voltage wiring on LED lighting and similar systems, not just CCTV
Termination
Both plug and socket use a cable mount design — the cable is clamped in, not soldered — so it's practical to fit with basic tools on-site rather than back at a bench.
Before you buy
Check the connector size on your existing cable or device matches 5.5mm/2.1mm. Not every 12V CCTV product uses this exact barrel size, so confirming first saves a second order.

Frequently Asked Questions
What size DC connector is this?
It's the standard 5.5mm outer diameter, 2.1mm inner diameter barrel size used on most 12V DC CCTV cameras, DVRs and NVRs.
Do I need to solder the connections?
No — both the plug and socket use a cable mount (screw terminal) design, so conductors are clamped in rather than soldered.
Can I use this to extend a camera's power cable?
Yes, this male/female pair is suitable for extending or terminating existing 12V DC CCTV power cables.
Will this work with LED lighting as well as CCTV?
Yes, it's suitable for any 12V DC low-voltage connection using the 5.5mm/2.1mm barrel standard, including LED power systems.
