CCTV 12v security camera power supply panel

If you've purchased a CCTV security camera, you will most likely need to power it. Security cameras are typically powered through a 12v security camera power supply, and are terminated at a remote panel.

The panel has punchouts in the back that allow for mounting just about anywhere. They are typically shaped about the size of a piece of copy paper, but with several inches in depth. They function similarly to a fuse or breaker box. As a matter of fact, typical 12v security camera power supplies come with their own fuses.

There is usually a main power switch in the front that allows you to turn off the power to all of your devices at once, unless it's a secure box, then the main power switch is inside. Inside the panel, you'll see screw terminals, which is the end-point for your 12v security camera power lines coming from the camera. You'll also notice the fuses, one for each 12v security camera power line.

Seeing that this device will be used for security, you may want to consider different mounting options and features. For example, you may want to hide the wires that are feeding into this panel, and you may want to run the wires behind the drywall. This is not for the faint of heart, as you'll need to feed them through the attic or plenum down the wall. If the wall has cross beams, this will stop progress. You can always drill through the cross beams, but this is much more work. However, typically, drywall construction does not usually include cross beams, and you'll be able to run the wires down the wall easily. Finding the wire at the lower end of the wall, however, will be your next challenge. You'll need a hole big enough to see the wire (and to be able to grab it), but small enough that it isn't obnoxious or exceed the panel's width and height.

You may also want to consider running the cables down a conduit, specifically, a metal conduit, to reduce electromagnetic interference. Do not run your cables alongside power cables or within power cable conduits, no matter how convenient this may be. The EMI generated from power cables is significant, and may interfere with the signal quality of your cameras, especially if you run your video/audio signal cables side by side next to your 12v security camera power cables.

Also, use drywall bolts instead of drywall anchors. Again, since this is a security device, you want it to be fully secure. Drywall bolts offer much better adherency to the drywall than drywall anchors.

If you go through all this trouble, you'll also want to purchase a 12v security camera power supply that has a locking mechanism. There's no since hiding the wires and using drywall bolts if you're not going to protect what's inside.

We usually point a hidden camera towards the panel, and have that camera send motion activated pictures to a remote location, that way, if anyone does try to break into your 12v security camera power supply panel, you at least have the evidence.

We hope this article helps in your selection of a 12v security camera power supply. Please leave us a comment, or post feedback if this helped, or if you have other recommendations.
