Looking at improving our home security and trying to make our house seem that little more difficult to break in to make thieves think twice. I know some will break in despite what measures are in place, but it may put off chancers.

We have some single glazing windows still downstairs in our house, so looking at the vibration alarms for windows. I also have a large single glazed window in the garage.

Has anyone advice regarding these alarms? any good? any brands to avoid?
