A good security system starts with the right wires. You can have the best camera or alarm in the world. However, if your wires don’t work well, nothing else matters. That’s where security cables come in. They’re the quiet heroes hiding behind your walls as they keep your systems running and your property safe.
Whether you're setting up a home alarm or a CCTV system for your business, understanding the cable for security is key. Don’t worry, since we’re keeping it simple. You don’t have to be an expert to get the basics right. Let’s talk about the wires that protect what matters most.
Understanding the AWG Numbers
Let’s talk about those tiny numbers you see on security cables, and that is AWG. It stands for American Wire Gauge. This number tells you how thick the wire is. Smaller numbers mean thicker wires, and thicker wires carry electricity better. That’s good for long cable runs or systems with heavy power needs.
For example, a 16 AWG alarm system wire is thicker than a 22 AWG one. The thicker wire can carry more current without heating up. But it also costs more and takes up more space. On the other hand, thinner wires are great for short runs and lighter systems like door sensors.
You’ll often see 18 AWG used in wiring for security systems at home. It’s strong enough for most needs and easy to work with. Just make sure to match the AWG with your system’s power needs and distance. Otherwise, you’ll get weak signals or dropped connections. That’s never a good thing when safety is involved.
So, when you're picking out a wire for an alarm system use, check the AWG number. It’s not just a detail. It's the difference between a smooth setup and a big headache later.
Coaxial Cable and Its Usage in CCTV Applications
CCTV systems depend heavily on the cables that connect everything. One of the most common types used is coaxial cable. This type of camera security cable is especially good for sending video signals over long distances. But not all coax is the same. Let’s walk through the different parts and types you should know.
RG59 and RG6 Coaxial Cable
The most common coaxial cables used for CCTV are RG59 and RG6. RG59 is thinner and more flexible. It works best for short cable runs, like in homes or small shops.
RG6 is thicker and better for longer distances. If you're installing wiring for a security system across a large building or yard, RG6 might be your go-to.
Coax Security Key and Signal Strength
The coax security key isn’t a physical key. It refers to the way coax cables keep video signals strong and clean. The solid copper core with shielding layers and insulation all work together to protect the signal from interference. That means your footage stays clear, even from far-off cameras.
Power and Video in One: Siamese Cable
Some security camera wire types combine power and video in one cable. These are called Siamese cables. One part is the coax cable for video. The other part is the power wire. This makes it easier to run one cable instead of two. It saves time, space, and frustration.
Indoor vs Outdoor Use
Coax cables are built to provide different functionalities. Some cables are meant for indoor use only, while others are made for outdoor setups and come with extra weather protection. If you’re wiring cameras outside, you’ll need a security cable with loops or jackets rated for outdoor conditions.
Cable’s Outer Jacket and Its Role in Fire Alarm and Security Cable
The outside of a cable matters just as much as what’s inside. The outer jacket protects the wires from fire, heat, and physical damage. When you're dealing with alarm wire or any security alarm cable, the jacket could even be the reason your building passes a fire safety inspection. Let’s look closer at what jackets do and what types you might see.
Plenum-Rated vs Riser-Rated Jackets
Plenum-rated jackets are used in spaces where air flows freely, like above ceiling tiles. They’re made to resist fire and give off low smoke. Riser-rated cables are for vertical spaces, like walls or shafts. Always choose the right jacket for the right job, especially for home security wiring.
Sunlight and Water Resistance
If your security cable camera setup includes outdoor cameras, the jacket must resist UV rays and moisture. Some secure cables have jackets made for wet or underground conditions. If you use the wrong jacket, the wires inside could corrode or short out.
Shielding and Interference Blocking
Some jackets have extra layers to block interference. These are key in areas with lots of electronic noise. That helps keep your video feed clear and your alarm system wire responsive. Shielding isn’t just for fancy setups, as it helps everyone.
Color Coding for Easier Installs
Jackets often come in colors like red for security alarm wire or white for surveillance camera wire. These colors help techs know what cable does what. Color-coding saves hours of guesswork and mistakes in big setups.
Durability and Flexibility
You want a jacket that’s strong but still easy to bend. Too stiff, and you can’t pull it through walls. Too soft and it might rip. A good alarm wire has that perfect middle ground.

Which wire is best for an alarm system?
For most homes, an 18/2 or 22/4 alarm system cable works well and meets common code requirements.
Can I use any coax cable for CCTV?
No. It is best to use RG59 or RG6 coaxial cables made specifically for CCTV to avoid signal problems.
What is a computer security cable?
A computer security cable is a physical lock that attaches your PC or laptop to a desk or surface.
