Product Description
A DC 2.1mm male power plug terminates a 12V cable without solder. It fits the 5.5mm x 2.1mm DC sockets found on most CCTV cameras, DVR power supplies and LED low-voltage fittings, so it's a straightforward re-termination part when a lead has been cut short, damaged, or needs a custom run.
Why installers use screw terminals here
Screw terminal connection means the positive and negative conductors are secured with a screwdriver on site — no soldering iron, no heat-shrink, no waiting for a joint to cool. That matters when you're re-terminating cable inside a camera housing, a junction box, or a power distribution enclosure where space and time are both tight.
Typical uses on a job
- Reterminating a CCTV camera power lead once it has been cut to length
- Building custom power runs for DVR/NVR power supplies
- Wiring LED and other low-voltage 12V DC equipment
- First-fix jobs where the run is pulled before the exact plug position is known
Fit and compatibility
Confirm the receiving socket is the standard 5.5mm outer / 2.1mm inner diameter DC type before ordering — this connector is sized specifically for that pairing and won't suit other DC socket sizes.
Practical note
On long cable runs, undersized conductors can cause voltage drop at the camera end, particularly once IR LEDs draw more current at night — worth checking cable gauge against run length when specifying this connector for a new installation.

Frequently Asked Questions
Does this connector need soldering?
No — it uses a screw terminal, so conductors are secured with a screwdriver rather than solder.
What socket size does it fit?
It's designed for standard 5.5mm outer diameter, 2.1mm inner diameter DC power sockets, common on 12V CCTV and LED equipment.
Can I use this on long cable runs to a camera?
Yes, but check your cable gauge against the run length first — undersized conductors can cause voltage drop, especially once IR LEDs draw more current at night.
