All the while I have worked in electronic security, we have stayed one step ahead of the criminals, burglars used to disable main, so batteries for stand by were added, bells were ripped of walls, so anti tamper and self actuating bells were developed, sounders and bells used to get filled with foam, so anti foam boxes were developed, wires were cut and shorted together in lofts, so eol was developed, detectors obscured, anti mask was developed. As soon as a loophole is discovered its closed. But as a technical person myself, I can see the weaknesses in non wireless systems let alone wireless, wireless systems to anyone with basic electronic skills and some inside knowledge is vulnerable
