Security Grilles vs Burglar Alarms
Most people have a Burglar Alarm fitted and believe that it provides a sufficient deterrent to thieves. Unfortunately this is not the case, I would say that nearly 90% of the burglaries I have attended has had a Burglar Alarm fitted.
The problem is that people ignore burglar alarms, because of the frequency of false alarms. The Police no longer accept direct alarm call outs, they go through a monitoring company, who usually won’t respond unless they get two forms of activation.
A security grille/shutter without an alarm can be attacked all day without anyone knowing about it. At least with an alarm sounding, the thief knows that they have been noticed and help maybe on the way.
The average time spend in a premises is 3 minutes, so by the time any one has responded to an alarm, its usually too late as the burglars have left. We have seen it where they have cleared a property in this time!!
We recommend that Grilles/Shutters and Burglar Alarms work together. The security grille/shutter will provide a Physical and Visual deterrent, while the alarm will hopefully attract some attention. If an alarm is fitted then the thief would have to break the glass, attack the grille through broken glass, whilst the alarm is sounding.
A lot of the times when I have visited break-ins, the alarm sensors are located in the wrong positions, so it hasn’t worked with the security grilles/shutters. It is has been known for a property to be burgled through the security grille and no alarm was activated, because the sensors were pointing the wrong way. I would suggest that you speak to your alarm company and try getting vibration sensors fitted to the windows/doors and getting the PIR sensors pointing toward the windows or door.
