Question
Dear Dave-
I am gettign an alarm system put in- wireless with a motion
detector.  do you recomend putting a sensor on every window
on the first floor and basement? is it neccesary if you  have a
motion detector ?
I am also a volunteer on this site and find it very rewarding.
hope you do to.
thanks, mary

Answer
Hi Mary, and thanks for your question.

Is motion detection important? Sure. Consider this: a window contact detects when the window (or door) is opened. But what happens if a burglar breaks the glass? With just a contact -- nothing.

Motion detection will detect a burglar's entry after breaking a window.

I hope this helps, and please write again if you have other questions.

Best Regards,

Dave
