Do people ignore ringing alarms?
Sadly yes, some members of the public will regard the noise made by an alarm as a nuisance. The good news is the burglar cannot rely on this indifference. He doesn’t know whether your alarm is monitored or if the police have been contacted. Only the most foolhardy burglar would have broken into an alarmed property in the first instance, but only an imbecile would remain in the property with the alarm bells ringing! Hopefully he will be leaving empty-handed and in a big hurry.
