DC Female Red & Black Power Pigtail 15cm 5.5x2.1mm Barrel Connector

The DC Female Red & Black 15cm pigtail is a pre-assembled power lead providing a reliable interface between central DC power supply units and CCTV cameras requiring barrel jack input. Featuring a standard 5.5x2.1mm female barrel connector mated to 15cm of flexible red/black insulated wire, it matches the DC input specification found on most Hikvision, Dahua and third-party analogue/hybrid cameras operating at 12VDC ±10%. The polarity-coded wiring (red = positive centre pin, black = negative barrel) eliminates reversal errors during installation, while the 18-22AWG conductor gauge supports 1-2A per lead—adequate for single camera loads or short parallel daisy chains from regulated PSUs. This pigtail integrates seamlessly into professional CCTV power architectures, connecting the DC output terminals of multi-channel 12V power supplies (found in data racks or field enclosures) directly to camera junction boxes, waterproof baluns or camera rear DC jacks. The 15cm length provides sufficient reach for internal camera wiring without excess slack, and the leads can be extended using Wago connectors, crimped barrel terminals or soldered joints into larger power bus cables such as 2-core security flex or alongside RG59/RG6 siamese runs for hybrid systems. Rated for indoor/outdoor use when protected within junction boxes (IP65+ enclosures recommended), it withstands typical rack-mount PSU ripple and voltage drop on runs up to 50m when paired with 1.5-2.5mm² supply cabling. Deployed across retail, perimeter and multi-camera site installations, these pigtails enable quick field termination from rack PDUs or remote power panels, reducing labour time compared to cutting/stripping bulk power wire. They maintain stable 1A+ delivery under full camera IR load without significant heating, complementing PoE IP systems where DC legacy devices persist in mixed infrastructures. Bulk packs facilitate scalable power distribution alongside Cat5e/Cat6 backbone cabling and NVR rack integration.
