Hidden doormat chime

Here is a cool way of knowing that there is someone at the door even before they knock or ring the bell! It is a nice early warning system for anyone who is being security conscious and that is just about anyone these days! It can also work for business users too, especially for people who are running their own business with no staff etc.
