No, it's more likely to make a loud noise. If you want it G get the monitored one as at least they are contracted to deal with the thing when it goes off.Well at the end of the day, a house with an alarm is absolutely less likely to be burgled than a house with no alarm.
Thieves will always go for the easier target.
Yeah I know what you mean. You read about these groups of chavs raiding houses and killing people well if you are worth millions you must be so paranoid about these things. It is one of the reason that should I ever win the lottery I would ask not to be named.
Yeah stories like this one. http://www.mirror.co.uk/news/uk-news/sons-horror-after-finding-77-year-old-3791735 I imagine the richer you are the more sophisticated the criminals become.Do you? Can't say I ever have.
In Ireland we have the phenomenon of "Tiger kidnappings", where someone is grabbed for ransom, but its usually bank keyholders and the like rather than just rich people, (although that has happened) but it doesn't seem to be a thing that happens in the UK much. I still wouldn't ask to be named, but not because of fear, just because everyone would have their hand out.
