CCTV Power Supplies

     CCTV Cameras can be powered in two ways. You can power each security camera with its own plug in power supply, or you can wire multiple cameras back to a multi-camera power source. Both options plug into a regular 110V electrical outlet and then step the power down to 12V DC to feed to the camera.

    Plug in power supplies are usually located within 6-10 feet of the camera. The multi-camera power supplies are installed in a closet or somewhere out of the way and then a two conductor power wire is pulled to each camera. When designing a surveillance system you may want to use a combination of plug in and multi-camera power supplies. This will depend on where your power outlets are located and how easily you can pull a wire from a multi-camera power supply to each camera. Multi-camera power supplies have one fused, dedicated power output for each camera. This design provides excellent protection from power spikes and surges.

    You should also know what protective function the camera power supply features such as over-current protection, output short circuit protection, and over voltage protection. The box that encases the power supply should be metal and durable, plus there should be an on/off switch and LED lights to go with each fuse.

    Other products that you might need in building and powering your CCTV system include AC to DC adapters and switching power adapters.

    And please be attention:

    High resolution cameras, Vari-focal cameras and PTZ Cameras will consume more power than regular ones, so it's better to use the single power adapter to keep the power quality.
