Coax Cables

Coaxial cables have been a staple in the security industry for many years. They continue to be a trusted standard for both analog and HD over Coax (HD-TVI, HD-CVI, AHD) systems. These cables provide a direct and delay-free transmission of video signals without the need for complex network configurations. Additionally, they offer a reliable and cost-effective solution for surveillance systems of all sizes.

When it comes to choosing the correct coax cable, there are a few factors to consider. One of the most important aspects to evaluate is the core material. The most commonly used materials for coaxial cable cores are copper and aluminum. Copper is known for its superior conductivity and durability, making it a preferred choice for high-quality video transmission. On the other hand, aluminum is a more affordable option but is not as efficient in transmitting video signals.

In contrast, RG6 coaxial cable is designed with a thicker 18 AWG center conductor and enhanced shielding. This makes it more durable and better equipped to handle higher frequencies and bandwidth. RG6 is the preferred choice for long-distance video signal transmission. Thus, it is ideal for commercial and large-scale surveillance systems. However, its stiffness can make it challenging to pull through walls. Because of this, it is better suited for new construction or installations where the cable can be run through conduit.

For professional installations, Siamese coaxial cable is the most efficient choice. This cable bonds a video coax run (RG59 or RG6) alongside an 18/2 stranded power wire that is jacketed together. As a result, this design allows for the simultaneous transmission of video and power using a single cable run. It eliminates the need for separate power cables, making the installation process more straightforward and cost-effective.
