Update:I had my sisters and their families up for a few days!
I have the system set to chime when a door /window is opened and that didn't seem to catch anyones attention.
latter that night while sitting around the fire place(was raining outside) the unit chimed!
Almost every one asked
"What is that?" I responded with
"The security system is telling me someone left the door open!", as I got up and closed the sliding door.
Everyone was amazed, I told them it would even phone me in the event of a break-in and allow me to listen in ,their eyes widened even more!
When I told them there was no monthly charge for that they were more amazed!
"Wow High tech features in a log home miles from nowhere" was one comment.
This unit continues to bring a smile to my face as well as peace of mind!
