And yet, a person who has an alarm in his house, and forgets to set it, will of course find that it doesn't sound in a burglary.
Do you know if this is the most common reason for an alarm failing to sound in a burglary? An interesting point if it is.
I notice nobody has denied it.
how can a box on a wall fail to sound if it isn't programmed to do so.?
Its doing its job.
The behaviour of the occupants is nothing to do with the alarm or the installer.
You are missing the point of the thread or at least the part introduced by Bernard.
His assertion was that Wirefree alarms are inherently insecure. He is so sure of this fact that he wishes that everyone who considers buying one is made aware of that fact.
The inference being that if you have a wirefree alarm , when you get burgled the alarm is not guaranteed to go off and is therefore a security risk.
My experience does not back this up either through anecdotal reports from wirefree alarm users or via a mass of publicly available evidence.
The only evidence so far presented to us all by Bernard proves the actual fact that inteference can indeed cause an alarm to detect inteference and then activate itself as a warning.
The fact the people in his report were burgled was not down to the alarm itself which acted as designed but down to the actions they consequently took which ignored addressing the problem or the cause of the inteference or indeed deciding to change to a wired system.
My counter argument is that inteference in my experience and in the lack of other supporting evidence, represents only a very very small hypothetical risk.
My assertion then was that users are in more danger of their alarm failing to operate when they are burgled because they forgot to set it or did not make it clear who was responsible for setting it (family scenario) than any possible security risk posed by inteference.
That is a perfectly valid argument.
It fits in logically when trying to establish the scale of the threat from inteference. It makes perfect sense to compare it to any other reason that an alarm may not work when expected.
It is strange that you somehow seem to think its not worthy of consideration.
You know yourself because the housing market slow that the biggest generator of domestic security installations at present is the fact that someone has been burgled and their existing system was not working or they did not set it (sometimes because they do not know the code or how it works as it was in the house when they bought it).
You cannot take those examples out of the equasion when making a determination on risk.
