Product Description
What this is
A male 5.5mm OD x 2.1mm ID DC barrel plug on a 15cm pigtail, centre-positive, terminating a PSU output before it feeds a camera's female DC jack. Sizing matches the female pigtails fitted to Hikvision, Dahua and generic analogue HD-TVI/AHD/CVI cameras.
Key specs
- Plug: 5.5mm OD x 2.1mm ID male barrel, centre positive
- Wire: 18-22AWG, red positive / black negative for polarity ID
- Length: 15cm
- Rating: 12-24VDC, 2A continuous
- Termination: pre-stripped ends for screw terminals, crimps or Wago blocks
- Insulation: PVC; screw-terminal variants available for no-solder field work
On the job
Use it to run a single camera feed off a multi-channel rack PSU's screw-block output, keeping DC power distribution separate from Cat5e video cabling. The 15cm length is short enough for tidy PSU-to-junction-box runs or fitting inside compact dome/turret housings without excess slack.
Pre-stripped ends mean no splicing before crimping or landing on a Wago block — useful when commissioning several camera drops off one PSU and wanting consistent polarity across the run. Pair with a female pigtail where an offset or extension is needed between PSU and camera location.

Frequently Asked Questions
What plug size and polarity does this pigtail use?
It's a 5.5mm OD x 2.1mm ID male barrel plug, centre positive, matching the standard size used on Hikvision, Dahua and generic analogue camera DC jacks.
How much current can it carry?
It's rated 12-24VDC at 2A continuous, which covers a single camera feed including IR load from a regulated PSU.
Can I terminate it without soldering?
Yes — the ends are pre-stripped for screw terminals, crimps or Wago blocks, and screw-terminal variants are available for no-solder termination.
Is this suitable for outdoor use as supplied?
The pigtail itself uses PVC insulation for indoor/protected wiring; for outdoor runs it should be housed in a suitably rated enclosure or junction box.
