DC Male Cable – Power Connector for CCTV and Low-Voltage Devices
The DC male cable is an essential power accessory used to connect CCTV cameras and other low-voltage electronics to a DC power source. It provides a secure and efficient way to supply power from a power distribution box, AC-to-DC wall adapter, or multi-camera power supply unit. Ideal for surveillance installations, DIY projects, and system maintenance, this cable simplifies custom power setups.
Key Function: Power Connectivity for CCTV Systems
This DC power connector male cable is primarily used to deliver 12V–24V DC power to security cameras and other compatible devices. It’s especially useful when working with power supplies that use terminal blocks instead of pre-installed plugs, enabling secure custom wiring in both residential and commercial setups.
Components and Construction
-
DC Male Plug (Barrel Connector): Standard 5.5mm outer diameter x 2.1mm or 2.5mm inner diameter cylindrical plug, compatible with most CCTV camera power inputs.
-
Cable: Two-conductor wire for power transmission.
-
Bare Wire Ends: The opposite end features color-coded exposed wire leads — typically red (+) and black (-) — for terminal block or custom connections.
Technical Specifications
-
Polarity: Center-positive (red = positive, black = negative), standard for most CCTV and electronic devices.
-
Wire Type: 14/38 flexible stranded copper wire — composed of 14 strands of 38 SWG, offering a balance of strength and flexibility.
-
Voltage Support: Commonly used for 12V DC systems, but compatible with 24V and up to 48V applications depending on insulation and gauge.
-
Current Capacity: Supports up to 2–5A, suitable for most single-camera power needs.
-
Material: Copper or tinned copper conductors with durable PVC insulation for long-lasting performance and corrosion resistance.
Applications and Use Cases
The dc male cable is widely used across security, IT, and electronics sectors for:
-
Connecting surveillance cameras to a central power box
-
Repairing or replacing damaged power connectors
-
Customizing cable lengths during installations
-
Connecting Siamese power cables to camera DC inputs
-
Low-voltage projects requiring stable DC power delivery
Compatibility
Pair with a DC power connector male female set or use independently with compatible terminal blocks, CCTV DVRs, routers, LED strips, and embedded electronics such as Arduino or Raspberry Pi projects.
Note: Always verify voltage, current, and polarity compatibility before installation to avoid equipment damage.
