My neighbour's house alarm is very sensitive and goes off all the time. Probably every day, sometimes twice a day.
It's not THAT loud.
Our other neighbour's alarm also goes off quite a lot, but not as much.
Ours doesn't go off ( or very very rarely ) because we set it with less sensitivity than theirs.
They each say they don't mind the false alarms and would rather just keep it on sensitive, but it doesn't bother them.
It's really starting to annoy us. Because the expectation is that you go look around outside and make sure all is well and then text them to tell them it's going off and coast looks clear ( even though everyone has CCTV as well ). I didn't make this rule, but it's what the others do when the alarms go off, so feels like you need to do that.
Sometimes I do just ignore it when I'm in the shower or whatever, but it's a nuisance. I just find it very strange the others always say it's not a problem and they'd rather they went off than we got burgled. However, I find that with so many false alarms, I just always assume it's a false alarm anyway.
It's just a bit tricky because we seem to be the only ones bothered.
