So it isnt surprising that youll find plent y of strong opinions about the potential vulnerabilities of popular home-
10、security systems.BThe 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 th e FBI, crimes like these accounted roughly two- thirds of all household burglaries in the US in 2013.The wide majority
11、of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal using technical means to bypass a security system areso small that the FBI doesnt even track those statistics.COne of the main theoretical home- security concerns is whether
12、or not a given system is vulnerable to being blocked from working altogether. With wired setu ps, 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

That appr oach will eliminate most cord-cutting concerns but what about their wireless equivalent, jamming? With t
14、he right device tuned to the right frequency, whats to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?DJamming concerns are nothing new, and theyre not unique to security systems. Any device thats built to receive a wirel ess signal at a speci
15、fic frequency can be overwhelmed by a stronger signal coming in on the same frequency. For compariso n, lets say you wanted to “jam” a conversation between two peopleall youd need to do is yell in the listeners 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 so knowwhat system theyre looking for. If you have a sign in your yard declaring what setup you use, thatd point them in the right direction, though at that point, were talking about a highly targ
