Why WiFi Jammers Are a Growing Threat to Home Security – And How to Protect Yourself

In today’s world, smart home security is more accessible than ever. From video doorbells to wireless cameras, it’s never been easier to keep an eye on your home – even when you’re miles away. But with these modern solutions comes a new and growing threat: WiFi jammers.

We’ve seen a rise in reports across the UK – including here in Suffolk – of criminals using jamming devices to block WiFi signals, effectively disabling wireless security cameras and doorbells during a break-in. These jammers are small, easily hidden, and worryingly cheap to buy online.

How Do WiFi Jammers Work?

WiFi cameras rely on your home’s wireless network to send notifications, upload footage to the cloud, or allow you to view live feeds remotely. A WiFi jammer emits a strong signal on the same frequencies (typically 2.4GHz or 5GHz), overwhelming the camera’s connection to the router.

Once jammed, the camera may stop recording, or worse, never detect or alert you to motion at all. This can give burglars a small but critical window to operate undetected.

Are All Wireless Security Devices Vulnerable?

In short – yes, if they rely solely on WiFi. Most consumer-grade devices like plug-and-play video doorbells or battery-powered cameras depend entirely on your home network and the cloud. That means:

• No internet = no alerts

• No WiFi = no cloud recordings

• No footage = no evidence

The Professional Difference: Hardwired Security Systems

This is where professional-grade systems have the edge. At AR Smart Systems, we install hardwired security cameras that don’t rely on WiFi or external internet connections to function.

Here’s why that matters:

• Wired connections between cameras and recorders are immune to WiFi jamming

• Local recording ensures footage is captured even if internet access is lost

• Tamper alerts can notify you if someone attempts to interfere with the system

• More stable performance in all weather and network conditions

Many systems we install, such as those from Ajax Systems and UniView offer hybrid solutions – with both network-based and hardwired options for added redundancy.
