Extend DC Power for Security Cameras

This 16.5ft extension cable carries 12V DC power to IP cameras, CCTV units or standalone DVRs using a 2.1mm by 5.5mm male-to-female barrel connector. It is built for installers who need to bridge distance between a power adapter and a device that accepts this exact plug size. The black jacket suits indoor or sheltered outdoor routing.

Pure Copper Core Reduces Voltage Drop

The cable uses premium pure copper conductors that lower resistivity and improve conductivity compared with thinner or alloy alternatives. This helps maintain stable voltage over the full 16.5ft run at loads up to 5A. It supports DC equipment rated from 5V up to a maximum of 56V, covering common 12V, 15V and 24V security power supplies.

Verify Plug Size and Voltage Before Buying

Confirm your camera or DVR uses a 2.1mm centre pin with a 5.5mm barrel; other dimensions will not fit. Ensure the power adapter outputs no more than 56V DC and the device draws 5A or less. The cable does not convert voltage or polarity, so the source and load must already match.

Questions about this item

Will the 2.1mm x 5.5mm barrel connector fit my camera's power port?

The cable uses a 2.1mm centre pin and 5.5mm outer barrel; it only works with devices that accept that exact size.

How do I connect the male-to-female plugs without reversing polarity?

Align the centre pin on the male plug with the female jack, push straight in until seated, then tighten the knurled collar; reversing the plugs swaps polarity and can damage 12V gear.

When should I replace the cable if voltage drop becomes an issue?

Pure copper conductors keep loss low up to the 16.5ft length at 5A; replace if insulation cracks, connectors loosen, or devices reset under load.
