RG59+2C CCTV Coaxial Cable: Specifications and Applications
The RG59+2C is a high-quality coaxial cable widely used in Closed-Circuit Television (CCTV) and video surveillance systems. It combines RG59 coaxial cable with two additional power conductors (2C) , making it ideal for transmitting both video signals and power supply to cameras in a single cable.
Features & Specifications
Cable Type: RG59 Coaxial + 2 Power Conductors (2C)
Impedance :75 Ohms
Conductor Material:Bare Copper / Copper-Clad Steel (CCS)
Shielding:Aluminum Foil + Braided Shield (95% coverage)
Outer Diameter:~6.0mm – 6.5mm
Voltage Rating :300V (for power conductors)
Frequency Range :0 – 3 GHz (suitable for analog & HD video)
Power Conductors :2 x 18 AWG (or 20 AWG) for DC power supply
Jacket Material: PVC (UV-resistant options available)
Applications
CCTV & Surveillance Systems
Transmits analog (CVBS) and HD (AHD, HD-TVI, HD-CVI) video signals while providing power to cameras.
Power over Coaxial (PoC) Systems
Some modern CCTV systems use RG59+2C for combined video + power transmission .
Long-Distance Installations
Suitable for runs up to 300m (for analog) and 150m (for HD signals) with minimal signal loss.
Indoor & Outdoor Use
UV-resistant jackets make it suitable for outdoor installations.
Advantages
Simplified Wiring : Combines video and power in one cable, reducing installation complexity.
Cost-Effective : More affordable than running separate power and video cables.
Good Signal Integrity :High shielding minimizes interference for clear video transmission.
Compatibility : Works with BNC connectors and standard CCTV power supplies.
Installation Notes
Use proper crimping tools for BNC connectors to ensure a stable connection.
For long runs (>200m), consider using signal amplifiers or higher-quality RG59 variants .
Avoid sharp bends to prevent damage to the inner conductors.
The RG59+2C is a versatile and reliable choice for CCTV installations , offering a balance of performance, durability, and ease of installation . It remains a popular option for both analog and HD surveillance systems due to its dual-purpose design (video + power) .
