Is this cable compatible with all security cameras?
Not exactly. It is only compatible with devices using a standard 5.5 × 2.1mm DC barrel power port. It is not compatible with USB-powered cameras, 3-prong plugs, or proprietary camera connectors.
My original plug is 5.5 × 2.1mm. Will this cable fit?
Not always. Even with a 5.5 × 2.1mm port, please check clearance. The plastic housing is approx. 11.55 mm wide and may block recessed/narrow ports. The metal plug tip is approx. 1.55 mm long. Ensure fit before purchase.
Does this cable support data transfer or video transmission?
No. This is a DC power extension cable only. It does not support data transfer, video signals, audio signals, USB communication, syncing, or display output.
Will voltage drop occur with longer cable runs?
Voltage drop may occur over longer runs or high-current setups. Avoid exceeding the recommended total length (15 m / 50 ft), and do not use long extensions for high-current devices or multi-device power configurations.
Can I use this cable outdoors?
Yes, for indoor or covered outdoor use. For outdoor installations, protect connection points from rain, snow, and standing water using a weatherproof enclosure or waterproof sealing tape.
