Can Burglars Jam Your Wireless Security System?

A)Any product that promises to protect your home deserves careful examination.So it isn't surprising that you’ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.

B)The most likely type of burglary(入室盗窃)by far is the unsophisticated crime of opportunity,usually involving a broken window or some forced entry.According to the FBI,crimes like these accounted for roughly two-thirds of all household burglaries in the US in 2013.The wide majority of the rest were illegal,unforced entries that resulted from something like a window being left open.The odds of criminal using technical means to bypass a security system are so small that the FBI doesn’t even track those statistics.

C)One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether.With wired setups,the fear is that a burglar(入室盗贼)might be able to shut your system down simply by cutting the right cable.With a wireless setup,you stick battery-powered sensors up around your home that keep an eye on windows,doors,motion,and more.If they detect something wrong while the system is armed,they’ll transmit a wireless alert signal to a base station that will then raise the alarm.That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent,jamming?With the right device tuned to the right frequency,what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?

D)Jamming concerns are nothing new,and they’re not unique to security systems.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.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.

E)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.They will,however,need to know what system they’re looking for.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.It’s easier to find and acquire jamming equipment for some frequencies than it is for others.

F)Wireless security providers will often take steps to help combat the threat of jamming attacks.SimpliSafe,winner of our Editors’Choice distinction,utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks.When the system thinks it’s being jammed,it’ll notify you via push alert(推送警报).From there,it’s up to you to sound the alarm manually.
