I had an entry sensor fall off a window last night.

I just discovered and purchased this gel tape to hang my Simplicams.  It works very well.  I had to move one of the cams to the other side of the wall and didn't bother changing or cleaning the tape.  It's holding just as strong. I've only been using it for a week now, but am considering using it on all my sensors.  You may want to look into it for your sensors.

Hey, that's pretty cool.  I can think of a lot of uses for something like this.  Thanks for sharing the link.
