We hope that you found it amusing but that said, we must be clear that we do take burglary very seriously and we think that the story does highlight the issue of faulty alarms, which is the main issue that creates apathy when it comes to responding to alarms. Too many false alarms dilute the effectiveness of a genuine alarm and can also be very annoying for neighbours.
The frequency of alarms going off would be greatly minimised if people were more vigilant about maintaining their alarms regularly. An annual service will usually keep your alarm working well and make sure that the batteries are replaced when required. It will eradicate most false alarms and the fewer alarms people hear, the more likely they are to take those that do go off seriously.
That said, an ice cream van chime would certainly get a response though you might have to stock up on Magnums to save disappointing a street full of ice cream lovers!
