The Basics of Security Cables

There are a variety of cables used for security applications; some of the more common ones being category cable, coaxial cable (such as RG59 or RG6), 18/2 security alarm cable, and 22/4 security alarm cable. 

Understanding the Numbers:

So what does 18/2 stand for? In the security industry, the first number represents the wire’s size, measured using the AWG (American Wire Gauge). 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 conductors you need depends on how many devices you will be connecting to with your cable.

Coaxial Cable

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

Fire Ratings

When it comes to fire alarm and security cable, one key feature to take into consideration is the cable’s outer jacket. These outer jackets can be made of special materials that burn differently if they ever were to catch on fire. For cable installation in plenum air spaces and/or 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.
