Unique-Bargains 20 Pcs 5.5mm x 2.5mm Male DC Power Jack Terminal Connectors surveillance accessory

20-Pack 5.5mm x 2.5mm DC Power Connectors

This pack contains twenty male DC power jack terminal connectors designed for CCTV camera installations. Each unit features a 5.5mm outer diameter and 2.5mm inner pin with a two-position screw-type terminal block. The connectors suit installers and technicians who need a reliable supply of standard power terminations for surveillance systems. Builders requiring different plug sizes or polarities should look elsewhere.

Sustained Connection Reliability

The screw-type terminal block secures bare wire ends without soldering, maintaining contact integrity over long cable runs. Plastic construction with integrated strain relief protects the wire junction from mechanical stress caused by vibration or cable movement. This design supports continuous power delivery to cameras without intermittent faults developing at the connector interface. The compact form factor fits inside tight junction boxes or camera housings.

Tool-Free Field Termination

Installation requires only a small screwdriver to clamp wires into the two-position terminal block, enabling quick field repairs or new camera deployments. The 3.8cm length allows sufficient working room for wire dressing in confined spaces. Common issues include over-tightening screws which can damage fine-stranded wire, and incorrect polarity wiring due to the unmarked terminal positions. Verifying polarity with a multimeter before powering the camera prevents equipment damage.
