Yep you can flame me all you want, I have mine installed above the door..
I will say the same thing I tell everyone that asks.
I own my own home, I pay the taxes.. Only full grown adults live in my home and both of us are fully aware of what is acceptable in the garage. We treat the garage will much respect, it is not a play place for Children or pets. The garage door is the least of the dangerous things that can be found in a garage. We do not leave things in the path of the door, let alone in the path were a 4,000 pound vehicle will be driving.. So you will not find a little red wagon, garden tools or small babies left in the path of our garage door. It is treated like it is a street. Now you will say.. what is a dog or cat wanders in to your garage? Well the owner of the said animal should have control of the animal so that it doesn't get in to situations like this. If you can not control or don't have enough responsibility to keep this from happening this is not really my problem. Also when the garage door is closing is it not quiet, most animals would be frightened but the sound and scamper away.
Now almost the same with children, I do not have children nor do I ever plan on having children. If I did have I would have enough responsibility to keep them out of the garage and to put all safety precautions in place to keep them safe in and on my property. Now if for some reason a 1 year old would for some reason stumble in to my garage and decide to take a nap on my garage floor right under where the door closes the door will come down with enough force to push on the child/red wagon or other human or earthy debris it will sense the resistance and go back up. Again it would seem to me that it is not my problem that someone else's child that they are 100% responsible for is my problem when they invade my private property. If you don't know where you little children and pets and red wagons are that is not for me to watch out for.
When I was little Dad taught me that if you slam a door on your finger it will hurt, or do anything else that could be taught to teach common sense that is not common today. When I was a kid we never had to IDIOT proof everything like we do today.. That is why it is so hard to find some people with common sense now.. Everything is Idiot proof and nothing teaches people right from wrong and we wonder why we are stuck with a pile of idiots..
Sorry Rant off
