Security Cable Basics

In the security and surveillance industry, there is some common terminology used for the installation of surveillance cameras, security alarm systems, and so on. Understanding the basic terminology used in this field can help make your installation easier.

First off, there are a variety of cables used for security applications. Some of the common varieties include category cable, coaxial cable (such as RG59 or RG6), 18/2 security alarm cable, and 22/4. This does not include all the other variations of security and fire alarm cable, but these are some of the options that you may commonly find.

Understanding the numbers:

So what does 18/2 stand for anyway? In the security industry, the first number quite simply stands for the wire’s size, measured using the AWG. In this example, 18/2 cable consists of a wire that is 18 AWG in size.

Additionally, the 2 in 18/2 represents how many conductors are present. This number can range quite a bit and how many you need depends on how many devices you will be needing to connect to with your cable.

Coaxial Cable

For running security cameras, the most well-known cable used for CCTV applications is RG59. This coaxial cable is best suited for low frequency applications such as running ongoing visual data in your security camera system. To transfer more data and at a faster rate, you can always switch to RG6, which is the upgrade for this cable.

Fire Ratings

An important note of consideration with fire alarm and security cable is the cable’s outer jacket. This outer jacket can be made of special materials that burn differently if they ever were to catch on fire. For cable installation in plenum air spaces/ open air ducts, it is best to install only plenum-rated cable. This is so that in case of a fire emergency, the cable would emit less toxic fumes and inhalation of this smoke would not be as dangerous to the body.

Riser-rated cable is used for floor to floor installations and is another cable fire rating used today. A good trick to note is that general purpose cable can always be used to substitute riser. In addition, plenum-rated cable can always work to replace riser.

Now that you know the essentials of the security industry, it is far easier to find the right cable for your application and to pair it with Primus Cable security cameras, video recorders, and accessories.
