Two-Pack Extension for Security Cameras

This two-pack supplies a pair of ten-foot DC power extension cables built for 12 V security equipment. Each cable carries a 2.1 mm by 5.5 mm barrel plug on one end and a matching jack on the other. The flat-profile wire slips through narrow gaps so installers can route power without drilling. Indoor and outdoor cameras, standalone DVRs and similar 12 V devices all accept the standard connector.

Replaces Short Factory Leads

The cables replace the short power cords that ship with most CCTV and IP cameras. The jump is worth it when the nearest mains outlet sits more than a few feet from the mounting point. Installers gain ten feet of reach per cable, enough to span eaves, soffits or interior mouldings. The pair covers two camera locations or one camera with a spare for future moves.

Limited to 2.1 mm by 5.5 mm 12 V Devices

The barrel interface only fits gear that uses the 2.1 mm by 5.5 mm plug at 12 V DC. Cameras or accessories with a different barrel diameter, a locking connector or a higher voltage will not mate. Reolink cameras and Amazon Echo devices are explicitly excluded. The flat cable eases routing but cannot carry data or support Power over Ethernet.

Questions about this item

What size barrel connector does the 10 ft cable use?

Both ends carry a 2.1mm x 5.5mm barrel connector, so the male plug and female jack match the same standard used by many 12 V DC camera adapters.

How do I route the flat cable through a window or door frame?

Slide the thin flat profile into the narrow gap of a closed window or door frame; no drilling is required, but avoid pinching the conductors when the frame shuts.

When should I replace the extension cable?

Replace it if the jacket shows cracks, the connectors become loose, or the camera loses power intermittently — any of these indicate wear that can interrupt the 12 V supply.
