Yes. After paying £90 for a metal shell the households displaying them don't have any spare cash worth stealing. Or if they did, they'd spend it on more non-functioning unstealable goods. It not metal, it's top quality premium yellow plastic!! They sell like hotcakes on eBay.. people like them because ADT systems are monitored so if the alarm goes off the control center call the police. If you have a row of houses and one has an ADT alarm box and the others don't, the idea is that the criminals will rob your neighbours and not your house with an ADT box. Thanks for the reply and info. Now I know the thinking behind the dummy boxes. Cheers!!
