Thanks fellas for the input.

ADT came and installed everything yesterday, and the sales guy came out after I got home to show us how to run it all at the same time (already showed my wife).

It IS all wireless, at least the sensors and motion detector are. We've got 4 sensors on the front of the house (windows and doors), 1 on the garage door, and each way into the house from the garage, plus one on each slider and the kitchen window. Motion detector set to shoot across front of house towards stairs. Wifey got a keychain fob arm/disarmer (pretty cool)...whereas my big ass'll have 30 seconds to get in and deactivate it...lol.

I was cleaning my guns when he came in. He said it looked like I had the second layer of security all taken care of...lol.

Anywho...I don't think we really need it, but if it gives her piece of mind, then why not?
