When setting up a CCTV system, choosing the right coaxial cable is crucial for ensuring optimal performance. Two commonly used cables in CCTV installations are RG6 and RG59. While they may look similar at first glance, there are significant differences between them that can impact the quality and reliability of your security system. In this article, we will take an in-depth look at RG6 and RG59 cables, comparing their features, performance, and suitability for various CCTV applications.
One of the primary distinctions between RG6 and RG59 cables lies in their structure.
**
RG6 cables typically have a thicker conductor compared to RG59. The conductor in RG6 is usually 18 AWG (American Wire Gauge), while RG59 often has a 20 or 22 AWG conductor. This thicker conductor in RG6 allows for better signal 传导 (conduction) and less signal loss over longer distances.
In addition to the conductor, the insulation layer in RG6 is also thicker. This thicker insulation provides better protection against external interference, such as electromagnetic interference (EMI) and radio frequency interference (RFI), which can degrade the signal quality in CCTV systems.
The shielding in RG6 is another area where it differs from RG59. RG6 often features a double shield, which can be a combination of braided shielding and foil shielding. This enhanced shielding helps to further reduce interference and ensures a more stable signal. RG59, on the other hand, typically has a single braided shield, which is less effective at blocking out interference.
The outer jacket of RG6 is also more robust, making it more resistant to physical damage, moisture, and UV rays. This durability makes RG6 a better choice for outdoor installations or environments where the cable may be exposed to harsh conditions.
Signal transmission distance is a critical factor to consider in CCTV installations, especially for larger properties or systems that require cameras to be placed far from the DVR or NVR.
RG6 cables are capable of transmitting signals over much longer distances compared to RG59. In general, RG6 can reliably transmit video signals up to 1000 feet (300 meters) without significant signal loss. This makes it ideal for large-scale CCTV systems, such as those used in commercial buildings, industrial facilities, or large residential complexes.
RG59, on the other hand, has a more limited transmission range. It can typically handle video signals up to around 500 feet (150 meters) before signal degradation becomes noticeable. Beyond this distance, the video quality may start to suffer, with issues like ghosting, snow, or loss of detail. For this reason, RG59 is more suitable for small to medium-sized CCTV installations, such as in small businesses or homes where the cameras are placed relatively close to the recording device.

With the increasing popularity of high-definition (HD) CCTV cameras, bandwidth has become an important consideration. Bandwidth refers to the amount of data that can be transmitted over the cable in a given time, and it directly affects the quality of the video signal.
RG6 cables have a higher bandwidth capacity than RG59. They can support higher frequencies, which is essential for transmitting HD video signals, such as those from 1080p or 4K cameras. The higher bandwidth of RG6 ensures that all the details and clarity of the HD video are preserved during transmission.
RG59, while sufficient for standard definition (SD) CCTV cameras, may struggle with the higher bandwidth requirements of HD cameras. Using RG59 with HD cameras can result in signal loss, reduced video quality, and even dropped frames, which can compromise the effectiveness of your security system.
Cost is often a factor in any installation project, and RG6 and RG59 cables differ in price.
RG59 cables are generally less expensive than RG6. This lower cost can make them an attractive option for budget-conscious installations, especially for small systems where the shorter transmission distance and lower bandwidth requirements of RG59 are sufficient.
However, it’s important to consider the long-term costs. If you anticipate upgrading to HD cameras in the future or need to cover longer distances, investing in RG6 from the start can save you money in the long run. Retrofitting a system with new cables later can be more expensive and time-consuming than installing the right cables initially.
The choice between RG6 and RG59 depends largely on the specific requirements of your CCTV installation.
For small residential CCTV systems with a few cameras placed close to the DVR, RG59 can be a viable option. It is cost-effective and provides adequate performance for SD cameras within a short range.
In commercial settings, such as retail stores, offices, or warehouses, where cameras may be placed at longer distances and HD video is often required, RG6 is the better choice. Its ability to transmit signals over longer distances with minimal loss and support higher bandwidth makes it suitable for these more demanding environments.
Outdoor CCTV installations also benefit from RG6’s more durable outer jacket, which can withstand exposure to the elements. Whether it’s rain, snow, extreme temperatures, or UV radiation, RG6 is better equipped to maintain its performance and longevity.
While both RG6 and RG59 are coaxial cables and share some similarities in installation, there are a few things to keep in mind.
Due to its thicker conductor and insulation, RG6 is slightly stiffer than RG59. This can make it a bit more challenging to work with, especially when bending or routing the cable in tight spaces. However, with proper tools and techniques, this should not be a major issue.
It’s also important to ensure that all connectors used are compatible with the chosen cable type. Using the wrong connectors can lead to poor signal quality and increased signal loss. Make sure to use high-quality connectors and properly terminate the cables to ensure a secure and reliable connection.
