PT-3 DC Power Lead Wire to Power Supply Box
The above diagram shows to use a PT-3 power lead to connect premade Siamese CCTV cables to a multi-channel power supply box. The 2.1mm femail end of the PT-3 plugs into the power portion of the Siamses cable. Then the raw cable ends connect to the power supply box with screw terminals. The BNC video end of the cable connects to the back of the DVR. (Not shown connected in the picture)
PT-4 Pigtail / Power Lead to CCTV Camera
The above diagram show how PT-4 leads are typically used when installing CCTV cameras with
premade Siamese coax cable. The
AHD-BL5H HD CCTV camera used in this example is a dual voltage camera, which means that it may accept a 12V DC or 24VAC power supply. Dual voltage security cameras almost always have a terminal blog to connect a power source to, instead of the standard 2.1mm female plug that most 12V DC only cameras have. The PT-4 is used to connect a the power cable on the pre-made Siamese cable to the camera. The raw cable end of the PT-4 attaches to the screw terminal block on the camera and the 2.1mm male connects to the female side of the Siamese cables.
In this example, a multi-channel power supply box is used (on the DVR end). So, a
PT-3 female power lead is used to connect the other end of the Siamese cable to the terminal block of the power supply box. You can view our complete PT-4 power lead wiring guide here.
Share a 12V DC Power Supply with 2 CCTV Cameras
The above installation / wiring diagram shows how the PT-102 can be used to share a single 12V DC power supply between two
HD CCTV cameras. This lead splitter can be used with analog CCTV, AHD, HD-TVI, HD-CVI and any other type of security camera (or other electronic device) that uses low voltage and standard 2.1mm power connections.
Power Lead Splitter for 2 Surveillance Cameras & 2 Audio Mics
The above installation / wiring diagram shows how the PT-104 can be used to share a single 12V DC power supply between two
HD security cameras and two audio surveillance microphones. This lead splitter can be used with analog CCTV, AHD, HD-TVI, HD-CVI and any other type of security camera, audio surveillance mic, or any other electronic device that uses low voltage and standard 2.1mm power connections.
