specific type of coaxial cable that is paired with two additional power wires. This configuration is commonly used for CCTV (Closed-Circuit Television) installations and other types of video surveillance systems. The "RG" stands for "radio guide," a designation from the military for coaxial cable specifications, while "59" refers to the specific type of coaxial cable. The "+2C" denotes the addition of two power conductors alongside the coaxial cable, typically used to power cameras or other devices directly, eliminating the need for separate power cables. Here are the advantages of using RG59+2C cable in installations:
1. Integrated Power Supply
The most significant advantage of RG59+2C cable is its integrated design that includes both signal and power wires. This allows for the transmission of video signals (through the RG59 coaxial part) and the supply of power (through the 2C, or two-core power cables) to the camera in a single cable run. This simplifies installation by reducing the number of cables needed to be run to each camera.
2. Cost-Effective Installation
By combining power and video transmission into a single cable, RG59+2C reduces the overall material and labor costs. There's no need to purchase separate power cables or to spend additional time and labor installing them. This can lead to significant savings, especially in larger systems with many cameras.
