Introduction

Choosing the right CCTV cable is crucial for ensuring the quality and reliability of your security system. The cable type impacts the signal quality, installation cost, and longevity of the system. This article will guide you through the different types of CCTV cables, important factors to consider, numerical parameters to help in decision-making, and solutions from Aston Cable Company.

Types of CCTV Cables

Coaxial Cables

Coaxial cables, such as RG59 and RG6, are traditional choices for CCTV installations. These cables transmit video signals over long distances with minimal signal loss.

Twisted Pair Cables

Twisted pair cables like Cat5e and Cat6 can carry video signals along with power and data. These are suitable for IP camera installations.

Power-Signal Cables

These cables combine power and video signals in one cable, such as Siamese cables, which include RG59 coaxial and a pair of wires for power transmission.

Factors to Consider

Distance

Distance affects signal quality. For up to 750 feet, RG59 is recommended, whereas RG6 is suitable for longer distances up to 1,500 feet.

Environment

Consider the environmental conditions such as temperature, humidity, and exposure to elements. Plenum-rated cables might be necessary for indoor public areas to meet fire safety regulations.

Signal Quality

Cables must support the resolution of your cameras. Higher quality cables such as RG6 or Cat6 are necessary for high-definition signals.

Numerical Analysis

Signal attenuation and impedance are critical numerical parameters to evaluate. Coaxial cables typically have an impedance of 75 ohms, while twisted pair cables often have 100 ohms.

  • RG59: Attenuation of 2.4 dB/100 feet at 50 MHz.
  • RG6: Lower attenuation, around 1.5 dB/100 feet at 50 MHz.
  • Cat5e: Supports up to 1 Gbps over 100-meter lengths.
  • Cat6: Supports up to 10 Gbps over 55-meter lengths in high interference environments.

Aston Cable Company Solutions

Aston Cable Company provides customized solutions tailored to different surveillance systems. They offer a range of cables:

  • High-performance RG6 cables with tri-shielding for superior noise resistance.
  • Premium Cat6 cables designed for IP cameras with excellent shielding and superior bandwidth.
  • Outdoor-rated Siamese cables with UV-resistant jackets for longevity in harsh conditions.

Conclusion

Choosing the right CCTV cable requires understanding the types of cables available, considering specific installation factors, and analyzing numerical parameters that affect signal quality. Collaboration with providers such as Aston Cable Company can ensure the selection of the most appropriate solution for your surveillance needs.
