Power Extension for Security Cameras

This 30ft 12V DC extension cable extends the reach of IP network cameras, CCTV systems and DVRs when a power outlet is not nearby. The 5521 barrel connector with 2.1mm by 5.5mm dimensions fits compatible devices directly. The two-pack provides spare cables for multiple camera locations.

Sustained Outdoor Power Delivery

High-quality materials resist harsh weather conditions for long-term outdoor installation. Superconductive wire inside maintains a stable power supply so cameras deliver a clear picture continuously. The flat cord design helps the cable lie flush along walls during permanent runs.

Verify Connector Compatibility First

Check that each camera and power supply uses the 5.5mm by 2.1mm 5521 barrel plug and jack before ordering. The cable supports 5V, 9V, 12V and 24V devices, but polarity and voltage must match your equipment. Enclosed nail-in clips and cable ties are included for securing the cable along walls.

Questions about this item

How much heat or power loss should I expect when running the 30ft 12V DC extension cable continuously?

The 30ft length uses superconductive wire designed for stable 12V or 24V delivery, minimising voltage drop so cameras receive consistent power without noticeable heat build-up during all-day operation.

What must my camera or DVR already have for the 2.1mm x 5.5mm 5521 connectors to work?

Your device needs a matching 5.5mm outer diameter and 2.1mm inner diameter barrel port; the female end plugs into your existing power supply and the male end connects directly to the camera or DVR.

Will the 5521 plug fit the power ports on my older CCTV cameras that use the same barrel size?

Yes, the cable is compatible with any legacy camera or DVR that uses the standard 5.5mm x 2.1mm 5521 barrel connector, regardless of brand or age.
