I think the door alarms are the way to go..The ones I bought were from Walmart..they have 2 pieces..put one on the door frame and one on the door..they touch each other..when the door opens and they are not touching...an alarm goes off..I would imagine you can use them on windows also..anywhere really.. I just want to know when the door opens..after that... I will scream while my husband clobbers them..(thats my plan and I'm sticking to it!!)
