Wiring a CCTV Camera to Power Supply Box with Premade Siamese Cable
This video shows installers how to connect a CCTV camera to a 12V DC power supply box using premade Siamese cables that have connectors already attached. The process is exactly the same for 24VAC power supply boxes, except that the cable polarity does not matter with alternating current (+ and - does not matter with 24VAC wiring).
Below are some examples of how multi-channel power supply boxes can be installed with analog CCTV cameras, HD security cameras, and audio surveillance microphones. We have the following complete how-to guides available. Please use the below links to access complete guides.
Here are the most common ways that power supply boxes are used in video and audio surveillance installations. Please access the detailed guides using the above links.
Security Camera Installation with RG59 Siamese Cable Spool
Here is a complete security camera system installation diagram that uses an RG59 cable, a 1080p HD CCTV camera (dual voltage), a hybrid AHD / HD-TVI / analog CCTV DVR, and a power supply box - which can be 12V DC or 24VAC. You can access the complete installation guide here.
Security Camera Installation with Pre-made Siamese Cable
This CCTV camera installation uses a pre-made Siamese cable with a power supply box. A PT-3 power lead allows the 2.1mm power plug on the pre-made cable to connect to the screw terminals of the power supply box.
Audio Surveillance Microphone Installation
The power supply boxes on this page can also be used to power low voltage audio surveillance microphones. For example, our best selling 12V DC audio surveillance microphone is very commonly paired with security cameras and our iDVR-PRO surveillance DVR to record video and audio. Professional and DIY installers can use premade Siamese cable or RG59 Siamese spools for this type of application. Access the complete audio surveillance installation guide here.
Pre-made audio video power cables are used in this example installation of a security camera and microphone, but this install uses a power supply box instead of an individual DC transformer. The PT-102 power cable splitter is still used to split the 2.1mm female power plug of the pre-made cable to two 2.1mm female power plugs to allows both the camera and mic to share the power supply. A PT-3 power lead is used to connect the pre-made cable to a 12V DC power supply box on the DVR side of the cable run.
