Home Security Tip : Noise in the garage.
I read your page on fitting a door viewer. I use mine every time I have to go to the door, I wouldn’t be without it.
I have also fitted one on the connecting door to the garage. Not that anyone is going to knock on that but I often hear noises. The noise is usually some animal scratching or walking across the garage roof, but with the viewer I can look to see and make sure, and I do not have to open the door. It puts my mind at ease.
