RG59 Camera Cable 100M Plus BNC Connections
RG59 Camera Cable 100M plus BNC connections – Surveillance cameras are being used more and more these days.
To begin with they add peace of mind to the safety of one’s home or business that cannot be equaled.
Today we will delve into the different wiring options available.
For hooking up both power and video for BNC-based security cameras.
RG59 Siamese is the typical cable used to transmit video from a camera to a DVR/Multiplexer or monitor.
Therefore provide power to the camera.
Generally it consists of a run of RG59 coaxial cable, and two 18 gauge wires.
This cable combo is called Siamese.
Because the jackets are molded together for easy installations.
RG59 coaxial cable is composed of:
The jacket of a coaxial cable is there to hold the entire thing together.
Therefore it also protects the delicate shield inside.
95% copper braided shield
This copper shield is actually a second conductor.
Also protects the signal running through the main center conductor.
From external electromagnetic interference.
Therefore this needs to be grounded at both sides of the cable.
The BNC connector provides such a ground.
This shield is especially important in Siamese cabling as there is power being run directly next to it.
The dielectric is foam filler that maintains a specific distance.
Between the pure copper shield and the center conductor for the entire length of the cable.
Solid copper center conductor
In the first place the center conductor is where the magic happens.
Therefore this carries the video signal taken from the camera, and delivers it to the DVR or monitor.

BNC connectors are crimped onto the RG59 coaxial cable to be plugged into the camera’s video port.
For power, some cameras have terminals to accept bare wire.
Others require a connector be attached to the wires to plug into the camera.
The red wire is positive, and the black wire is negative.
If you only have a few runs, we carry pre-terminated cables with BNC connectors and power connectors already installed.
