Yes, that 'key fob' panic button is a wonderful tool. It will always be handy!
Here is something I found on-line last night. Uniden makes this small and inexpensive (about $135.00) surveillance camera and monitor wireless system. This, to Linda and me has a lot of potential. We will probably purchase this and a second outdoor camera. Look it over and let us know what you think!

If I did this right, the first image is the monitor and 'indoor' camera and the second image is an outdoor (waterproof) camera. I think they are pretty small and could be easily concealed or camouflaged for easy outdoor placement. This will also show the 'black bears' and other critters roaming around the campsite also! I like gadgets and knowing what is going on outside, but this may not interest everyone. It's all about options and being safe. I also have a couple of nice solar lights that will be mounted on 4 foot gray PVC pipes screwed into flanges located on either end of the tongue mounted cargo tray on the front of the trailer.
A convex mirror placed somewhere outside your trailer (by you) that you could look into when peeking out your door would show anyone trying to hide off to the side of the door. You could probably place it so that it wouldn't be too obvious to an intruder. Just another idea to consider.
Best to everyone,
Clyde and Linda
