![]() He'll need to be jamming you at this point, as a broken window or opened door would normally trigger the alarm. That means defeating the lock somehow, or breaking a window. Presumably, you keep your doors locked at night and while you're away, so the thief will still need to break in. Then, he's going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. First, a thief is going to need to target your home, specifically. Let's imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming algorithm like the one we tested from SimpliSafe. ![]() But how plausible is it that someone will successfully jam their way into your home and steal your stuff? As said before, with the right equipment and the right know-how, it's possible to jam any wireless transmission. I've reached out to ask for the latest on the company's jamming protections, and will update this space when I hear back. Even if they could, SimpliSafe told us in 2015 that its algorithm is always evolving, and that it varies slightly from system to system, which means there wouldn't be a universal magic formula for cracking it. It means that a thief likely wouldn't be able to Google how the algorithm works, then figure out a way around it. We like the proprietary nature of that software. If you have a sign in your yard declaring what setup you use, that'd point them in the right direction, though at that point, we're talking about a highly targeted, semi-sophisticated attack, and not the sort of forced-entry attack that makes up the majority of burglaries. They will, however, need to know what system they're looking for. Security devices are required to list the frequencies they broadcast on - that means that a potential thief can find what they need to know with minimal Googling. Buying or selling these devices without the right certifications is often illegal, too. It also requires criminal intent, because jamming is highly illegal. Jamming a wireless radio requires knowledge of its broadcast frequency as well as the right equipment to jam that frequency. For comparison, let's say you wanted to "jam" a conversation between two people - all you'd need to do is yell in the listener's ear. ![]() Any device that's built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. ![]() Jamming concerns are nothing new, and they're not unique to security systems. We tested wireless jamming out for ourselves in this odd-looking setup designed to contain the RF interference. ![]()
