This is a great way to add added security to your home. We have ADT but wanted something for when we didn't want the alarm system all the way on.
THESE WORK GREAT!!!!
**I did try the ones at Lowe's first by GE, but they were not reliable enough for me. They were not very loud and didn't go off EVERY TIME I stepped in front of them . These go off EVERY TIME. I got these from Home Depot. They are called Doberman Security.
** The larger ones take a 9 volt battery, not included. The ones for the doors come ready to turn on. Batteries included.
Let me know if you have used these and how you like them. Or if you decide to try these, let me know how you like them.
