Product Description
Overview
A 50cm male DC barrel pigtail (5.5mm OD x 2.1mm ID, centre positive) for extending 12-24VDC runs to analogue HD-TVI/AHD/CVI cameras from a rack PSU or junction box.
Key specs
- Plug: 5.5x2.1mm male barrel, centre positive — mates with standard female DC jacks on analogue cameras
- Wire: 18AWG red (positive) / black (negative), colour-coded for fast polarity checks
- Rating: 2-5A continuous at 12-24VDC — covers single-camera loads or parallel bus wiring
- Length: 50cm — suited to rack PSU-to-junction-box runs or offset camera positioning where 15-30cm leads don't reach
- Termination: pre-stripped ends for screw terminals, crimps or Wago-style lever blocks — no soldering required
- Insulation: flame-retardant PVC over pure copper conductors, reducing voltage drop on the longer run
Install notes
Use with female barrel pigtails to build DC extensions where camera position sits away from the PSU. On multi-channel racks feeding IR-heavy loads at night, keep cable runs short and conductors sized correctly — voltage drop on long or thin runs is a common cause of IR flicker or dropout after dark. Compatible with Hikvision/Dahua hybrid setups run alongside siamese RG59 or rack-mount PSUs; pairs with structured installs also carrying Cat5e or RG6 backbone cabling.

Frequently Asked Questions
What is the plug size and polarity?
5.5mm OD x 2.1mm ID male barrel plug, centre positive, mating with standard female DC jacks on analogue HD-TVI/AHD/CVI cameras.
What current and voltage can the leads handle?
The 18AWG red/black wire is rated 2-5A at 12-24VDC, suitable for single-camera loads or parallel bus wiring.
How are the wire ends finished?
Ends are pre-stripped, ready for screw terminals, crimps or Wago-style lever blocks without soldering.
Why choose 50cm over a shorter pigtail?
The extended length suits rack PSU-to-junction-box runs or offset camera positioning where shorter 15-30cm leads don't reach.
