Hi,
Have 6ft and 4ft wide double glazed upvc windows, typically the 6ft ones have two outer main openers with a fixed middle pane and a small opener above it.
Seems like the small stick on glass alarms might offer a good extra layer of security for the bungalow, but wondered what opinion was of these units like the Swann or Glass Minder devices.
Assume its necessary to fit one alarm to each pane of glass or is a single one fitted to the middle fixed pane sensitive enough ?
Have seen the IR beams but from reading though some of the forum posts seems they can be problematic; and if fitted inside, then it means they are already in.
Is there any other sensor / method I should be looking at instead /as well as ?
thanks
