Extra side note: There seems to be an endless supply of folks knocking on your door during the day selling all sorts of stuff. One time I was sitting near the front door and heard the door handle move. Someone leaving fliers actually check to see if the door was locked. I leaped up and confronted him and he said he was trying to tuck the flier in the handle. Cops notified, no further details. But now we have a dog that barks when someone is near the front door– very handy. (I know you have cats…just saying)[/quote]
During last summer this was a tactic used by a group of high school students when school was out. They would pretend to be delivering something or visiting, check the door find it unlocked an enter. Another method was ringing the door bell, waiting for no answer then going around back and making a forced entry. This is a good strategy in neighborhoods which are generally low crime as many residents don’t even bother to lock their doors or close their windows.
To stay on topic:
I have considering installing a wireless unmonitored system such as the one linked below. I am curious if anyone else has some experience with this product or something similar.
