Product Description
A male 5.5x2.1mm DC barrel plug on a 15cm red/black pigtail, used to terminate power supply outputs before feeding female DC jacks on analogue and hybrid CCTV cameras. Centre-positive, standard OD/ID sizing matches Dahua and generic analogue HD-TVI/AHD/CVI camera pigtails.
Key specs
- Plug: 5.5mm OD x 2.1mm ID male barrel with centre positive polarity
- Wire: 18-22AWG, red positive / black negative, polarity-coded
- Length: 15cm
- Rating: 12-24VDC, 2A continuous
- Ends are pre-stripped, ready for screw terminals, crimps or Wago blocks
- Insulation: PVC; screw-terminal variants available for no-solder work
Where it fits on a job
On multi-camera installs, this pigtail connects a PSU's screw-block output to a single camera feed, so it sits well alongside Cat5e patch panels and PDUs where DC power runs independently of video cabling. The short 15cm length suits direct PSU-to-junction-box wiring or fitting behind compact camera housings, rather than long cable runs.
Sizing and power notes
The 2A continuous rating covers a single analogue or hybrid camera feed, including IR load, from a regulated multi-output PSU — check the camera's actual current draw against this figure before wiring in multi-channel rack setups. Pre-stripped ends mean no splicing is needed when terminating into screw terminals, crimps or Wago blocks during structured cabling work.

Frequently Asked Questions
What size barrel plug is this?
It's a standard 5.5mm OD x 2.1mm ID male barrel plug, centre positive, matching female DC jacks on analogue and hybrid CCTV cameras.
What current can it carry?
It's rated 12-24VDC at 2A continuous, suitable for a single camera feed from a multi-channel rack power supply.
Does it work with Dahua or generic analogue cameras?
Yes — the 5.5x2.1mm centre-positive plug mates with female DC pigtails on Dahua and generic analogue HD-TVI/AHD/CVI cameras.
How do I terminate the wire ends?
The ends are pre-stripped for screw terminals, crimps or Wago blocks, so no soldering is needed for standard field termination.
