Can Thieves Tamper with Your Wireless Alarm System?

Back when hardwired home security systems were widespread in American homes, a common concern was whether or not a burglar would cut the line, rendering one’s home security system useless. Since systems were connected to a phone line for the purposes of home monitoring, all that a burglar would have to do was to locate it and cut it.

Today’s technology has opened up the door to wireless home security systems, taking away the concern for a burglar’s potential ability to disable your system. But the question once again remains: is there a way for a burglar to disable someone’s wireless alarm system?

Luckily for home security customers today, the chances of having their wireless home alarm system disabled due to tampering is very small.

It would take a rather significant amount of work on the part of the burglar, and if the past has taught us anything, it is that burglars like to move in and out of homes as quickly as possible.

So if a burglar were to actually disrupt a wireless alarm system, just how would it be done? In one word: jamming.

Wireless home alarm systems are built to receive wireless signals at a designated frequency. If another device comes into play that is capable of “jamming” that frequency, a disruption would occur.

The thing is, not just anyone can go ahead and jam a signal on the spot. The practice, which is highly illegal, requires a basic understanding of how broadcast signals work, as well as special equipment.

On top of that, the burglar doing the jam needs to know what kind of wireless security system you have, since different systems receive different signals. As mentioned, it takes a lot of work and knowledge for the burglar to jam your wireless alarm system.

Luckily, companies that manufacture wireless home alarm systems keep the possibility of a frequency jams in mind, and build counteractive features to help combat any attack.

In the event that you have a wireless home alarm and experience an attack by someone, your system should notify you that a security-compromising event is taking place. At the least, you’ll be notified of a signal disruption of your system via email or text message.

So in short, while thieves can disarm your wireless alarm system, the likelihood of it happening is rare. There is not even enough data on the frequency in which jamming attacks take place. It’s a time-consuming practice that most burglars – unless they are really interested in attacking one specific home – aren’t interested or knowledgeable enough to even try.

What studies do show is that a burglar is less likely to attack a home that they know is armed with a home security system. Homes that aren’t backed by home security are more likely to be targeted.

Be sure that when you are shopping for a wireless home alarm system, bring up the concern of disruption to the companies you are looking at. They should be able to show you any anti-disruption features that come with the system.
