When you decide to install CCTV at home, a system of video cameras used to monitor property for security purposes. Also known as closed-circuit television, it’s one of the most direct ways to protect your house, deter intruders, and check in on what’s happening when you’re away. But buying a camera isn’t enough. Where you put it, how it connects, and whether it actually works in the dark or rain make all the difference.
Most people think wireless CCTV, cameras that transmit video without physical cables, often using Wi-Fi or cellular signals. Also known as Wi-Fi security cameras, they’re popular because they’re easy to set up is the best choice. And sure, they’re convenient—no drilling, no wires. But they can drop signal, die when the power goes out, or eat up your internet bandwidth. Then there’s CCTV installation, the process of setting up security cameras with proper placement, power, and connectivity to ensure reliable monitoring. A professional install isn’t just about mounting a camera. It’s about avoiding blind spots, choosing the right lens for your driveway or back door, and making sure the system works when you need it most.
And let’s talk about home security cameras, devices designed to capture video of residential property for surveillance and evidence. Also known as security cameras, they come in all shapes—some with night vision, others with thermal imaging, and a few that only work in daylight. If you live in a dark neighborhood, night vision alone won’t cut it. Thermal cameras see heat, so a person hiding in bushes still shows up. But they cost more. You also need to know where you can’t install them. Pointing a camera at a neighbor’s window or your own backyard where people change clothes? That’s illegal in the UK. And if your camera is too high, too low, or blocked by a tree, you’re wasting your money.
Cost is another thing people get wrong. You see ads for £99 CCTV kits and think you’re getting a deal. But those often don’t include storage, professional setup, or reliable cloud backup. Real systems—ones that actually record and let you review footage when needed—start at £300–£600 for a basic 4-camera setup with professional installation. And that doesn’t even include a monitor or extra batteries. If you’re going to install CCTV at home, spend on the right parts. A camera that freezes in rain, loses signal every time it rains, or can’t tell a cat from a person isn’t security—it’s a distraction.
What you’ll find below isn’t a list of the best cameras. It’s a collection of real-world tests, mistakes, and fixes from people who’ve been there. You’ll learn why some wireless cameras fail in winter, how battery life really works, what to avoid when placing cameras outside, and whether thermal or infrared is better for your property. There’s no fluff. No marketing hype. Just what works—and what doesn’t—when you’re trying to keep your home safe.
Yes, you can install CCTV outside your house in the UK - but only if you follow privacy laws. Learn where to mount it, which cameras work best, legal rules, and how to avoid fines or neighbor complaints.
