33 ft 2.1 mm × 5.5 mm DC extension

This 33 ft black cable carries 12 V DC power from an adapter to a CCTV, IP Wi-Fi camera or standalone DVR. The 2.1 mm × 5.5 mm female-to-male barrel connectors match the standard jack used by many security devices. Pure copper conductors keep resistance low so voltage arrives at the load with minimal drop. It is built for installers who need a longer reach without splicing.

Replaces short factory leads on security gear

The stock cord on most cameras and DVRs is only a few feet long, forcing the power supply to sit near the device. This extension lets you route the adapter to a convenient outlet up to 33 ft away. The upgrade is worth it when the nearest mains socket is across a ceiling void, down a wall or outside the camera housing. It does not help buyers who need a different barrel size or a higher voltage rating.

Pure copper keeps voltage steady on long runs

Lower resistivity in the copper core reduces attenuation so the camera sees a stable 12 V even at the full 33 ft length. The jacket resists abrasion during pulls through conduit or along cable trays. Performance stays consistent whether the load is a single IP camera or a DVR with multiple channels. No active electronics are inside, so there is nothing to overheat or fail under continuous operation.

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 x 5.5mm female-to-male barrel plug designed for devices accepting that exact plug size. It will not work with other connector dimensions.

How do I connect the 33ft extension between my 12V adapter and the camera?

Plug the male barrel end into the camera or DVR power input and the female jack into the 12V adapter output. Ensure both connections seat fully to avoid intermittent power.

Does the pure copper cable require any maintenance over time?

No routine maintenance is needed for the copper conductors. Inspect the jacket and connectors periodically for physical damage if the cable runs through high-traffic or outdoor areas.
