There are no wired communications in our neighbourhood and burglars have been using these for a long time to disable alarm systems. They use broad spectrum ones because alarm systems use anything from radio, wifi, 2g,3g,4g,5g to send info and contact the authorities. Some people have put up jammer detectors hooked into the sirens; it cannot call the police so then better make more noise. |
