Demystifying CCTV Cable Types for Video Surveillance Systems



When it comes to video surveillance systems, one of the key components that often gets overlooked is the choice of CCTV cables. While cameras, recorders, and software play a significant role in the overall effectiveness of a surveillance setup, the importance of selecting the right cables cannot be overstated. The right cable type ensures clear and reliable transmission of video signals, minimizing the risk of data loss and interference. In this article, we will delve into the world of CCTV cables, exploring their types and helping you make an informed decision for your video surveillance system.

The Role and Importance of CCTV Cables

CCTV cables form the backbone of any video surveillance system. They are responsible for carrying the video signals from the cameras to the recording and monitoring devices. Choosing the right type of CCTV cable is crucial because it impacts the quality and reliability of the video transmission.

Understanding Coaxial Cables

Coaxial cables are the most commonly used cables in video surveillance systems. They consist of a copper core surrounded by an insulating layer, a conducting shield, and an outer protective sheath. Coaxial cables are available in various types, such as RG59, RG6, and RG11, each offering different characteristics and performance levels.

RG59 Coaxial Cable

RG59 coaxial cables are widely used in CCTV systems due to their affordability and compatibility. They have a smaller conductor and thinner shielding compared to RG6 and RG11 cables, making them suitable for shorter distance video transmission. RG59 cables can transmit video signals up to a maximum distance of around 600 feet without any significant loss in quality.

RG6 Coaxial Cable

RG6 coaxial cables are an upgrade over RG59 cables when it comes to longer video transmission distances. With a thicker conductor and better shielding, RG6 cables can transmit video signals up to a maximum distance of around 1,000 feet without compromising signal quality. RG6 cables are ideal for installations where cameras are placed far away from the recording and monitoring devices.

RG11 Coaxial Cable

RG11 coaxial cables are the thickest and highest performing cables among the three types. Offering maximum transmission distances of up to 1,500 feet without any significant signal loss, RG11 cables are suitable for large-scale surveillance systems and installations where long-distance transmission is necessary. However, RG11 cables are more expensive and less flexible compared to RG59 and RG6 cables.

The Advantages of Cat5e/6 Cables for CCTV

Cat5e/6 cables, also known as network cables or Ethernet cables, are primarily used for data networking. However, they can also be used for transmitting video signals in certain video surveillance systems. These cables offer several advantages over coaxial cables, making them a popular choice for modern CCTV installations.

Flexibility and Future-Proofing

Cat5e/6 cables are highly flexible, allowing for easy installation and termination. With their ability to support both video and data transmission, they offer future-proofing capabilities, allowing for potential upgrades and integration with other systems.

Power Over Ethernet (PoE) Capability

One significant advantage of Cat5e/6 cables is their ability to deliver power to the cameras through the same cable used for video transmission. This eliminates the need for separate power cables, simplifies the installation process, and reduces clutter.

Extended Transmission Distance

While the maximum transmission distance of Cat5e/6 cables for video signals is generally shorter than coaxial cables, advancements in technology have increased their reach. With the use of media converters or Ethernet extenders, Cat5e/6 cables can transmit video signals over longer distances, providing a cost-effective solution for medium-scale surveillance systems.


In conclusion, selecting the right CCTV cables is essential for ensuring optimum video signal transmission in a surveillance system. Coaxial cables, such as RG59, RG6, and RG11, offer various options based on the required transmission distance. On the other hand, Cat5e/6 cables provide flexibility, power over Ethernet capability, and future-proofing advantages. Carefully evaluating your system's needs and considering factors such as distance, cost, and integration requirements will help you make an informed decision when selecting the appropriate CCTV cable type for your video surveillance system. Remember, choosing high-quality cables is as important as investing in top-notch cameras and recorders to achieve the best possible performance for your video surveillance setup.
