30ft DC 5521 Extension Cable for Cameras

This 30ft extension cable extends the power reach of IP network cameras, CCTV security cameras and DVRs that use a 5.5mm by 2.1mm barrel connector. The two-pack supplies enough length to route power around walls or ceilings without nearby outlets. Homeowners and business owners can install cameras in optimal positions rather than only where power exists.

Barrel Connector Compatibility Limits

The cable carries 12V DC power through a 5521 5.5mm by 2.1mm male-to-female barrel plug, so it only works with devices that share this exact connector size and voltage requirement. It supports 5V, 9V, 12V and 24V equipment, but polarity and current draw must match the camera specification. Longer runs may introduce voltage drop that affects sensitive devices.

Verify Plug Size and Voltage Before Buying

Check that every camera and recorder uses a 5.5mm outer diameter and 2.1mm inner diameter barrel port with centre-positive wiring. Confirm each unit operates at one of the supported voltages and that its current draw suits the cable gauge. Ensure the 30ft length reaches your planned mounting points without excessive slack or tension.

Questions about this item

Should I choose the 30 ft white 2-pack or a different length for my camera run?

The 30 ft white 2-pack gives two cables each 30 ft long; pick a shorter option only if the camera is closer to the power source and a longer one only if the run exceeds 30 ft.

What does the 12 V 24 V rating mean when the cable is connected to my camera?

The cable carries whatever voltage the power supply provides — 5 V, 9 V, 12 V or 24 V — so the camera receives the exact voltage its own adapter outputs.

The plug is described as 5521 2.1 mm 5.5 mm; what does that cap in practice?

It limits use to devices with a 5.5 mm outer diameter and 2.1 mm centre pin barrel jack; any other barrel size will not fit without a separate adapter.
