Security camera installers can use a CCTV power supply box, also known as a security power distribution unit, to concentrate the power source of several cameras to a single location. Wiring becomes neater and easier to manage when used with RG59U siamese cable or video baluns. Instead of having a separate power source for each camera, all of them can be connected to a single power supply box.

Near your DVR, you’ll usually find power supply boxes. Installation of these boxes is a breeze. The power cord for each camera simply plugs into the power distribution block within the box. A regular power outlet is used to plug the power supply box in. In this article we learn how to install CCTV power supply boxes, just keep reading.

Installers of surveillance systems may simply control the power to various CCTV cameras using a CCTV power supply box, also known as a power distribution box (usually at the location of the DVR). This enables a cleaner camera installation.

Surge protection can be accomplished in two ways. There is a standard fuses security camera power supply box and a PTC auto-reset fuses security camera power supply box. The PTC has the benefit that it does not burn out. When a circuit is overloaded, the PTC disables the circuit. The PTC automatically resets the fuses when the load is fixed. As a result, there are no burnt-out fuses to replace.

Installing these boxes is a breeze as long as you use products from reputable enclosure manufacturers. The power cord for each camera simply screws into the box’s power distribution block. A regular power outlet is used to connect the power supply box. Installation does not necessitate the use of an electrician. PTC auto-reset fuses are now used in all of our boxes.

Normally, you’d install your power supply box near your DVR on a wall. A typical 110-120 volt AC power wall socket with a 3-prong power chord would be used to power the box. For the power supply box, there is a power switch. It activates all of the ports.

It’s crucial to know how to connect cameras to a CCTV Power Supply Box, whether you’re installing one for a new or old camera system. DC is polarized, which means it has two leads: a positive red lead and a negative black lead. Using a Siamese coax cable with a two-lead power wire or a power pigtail, connect a security camera to a power box. It’s critical to recognize that DC electricity has positive and negative wires. Negative wires are black, while positive wires are red. To avoid harming the camera, the leads must match the corresponding color in the power box.

What are the requirements for connecting a security camera to a power supply?

A custom electrical enclosure is recommended in a camera system because it enables consistent power delivery. Using a power box instead of individual 12V power sources for each camera allows for a cleaner installation.

The importance of a power supply for your video security cameras cannot be overstated. Installers and users should use a high-quality power supply to ensure the stability and reliability of their video surveillance system. Image distortion, flickering, and even security camera hardware damage can all be caused by a poor power supply.

Outdoor security cameras typically use a 12V DC power source, while PTZ cameras use a 24V AC power supply. Some security cameras may use 220V AC power, and inside security cameras commonly use a 5V DC power supply.

A power supply is required for all security cameras. In most security camera systems, power boxes and power converters are employed. Most installers will utilize a power adapter and splitter if installing four or fewer cameras, but a power distribution box if installing more than four cameras. If you’re looking for a power adapter, make sure it is from a reliable electrical enclosure manufacturer and can handle the voltage you’ll be using.


Power supply boxes consolidate all of the power for your security cameras into one area, resulting in a considerably neater wire arrangement. At E abel, Our specialists take pride in the work we do and the products we sell. We always appreciate customer queries, so feel free to contact us.
