Not here for a long time but here for a good time!
My dog as an alarm has too many false alarms to be practical. 
Welcome to the Portal from South Carolina. Question posed in post #1 was for a door alarm on a camper.I have got a really great rind doorbell alarm. I like really much, and I consider it as one of the first things you should get, when moving into a new house.
It's likely that anyone with bad intentions would run when the alarm went off.

There is a reason you don't hear about it, it would be like digging out of prison with a spoon.Truthfully you could get in many houses with one of these. Vinyl siding and fiberboard underlayment, then drywall, walk right through the studs lol. It's somewhat interesting you don't ever hear about that ever happening.

I have done construction. You are not going to cut through OSB or ply in a good while with that knife.Have you ever done siding/sheathing work? I have. It's shocking how little it takes to cut through vinyl and that old-style fiberboard.
I've seen Habitat for Humanity houses put up with vinyl siding, foam board, insulation, and drywall. The only plywood or OSB was at the wall corners. The utility knife was a master key.I have done construction. You are not going to cut through OSB or ply in a good while with that knife.
I have never seen sheathing done that way in my lifetime.I've seen Habitat for Humanity houses put up with vinyl siding, foam board, insulation, and drywall. The only plywood or OSB was at the wall corners. The utility knife was a master key.
Guess you couldn't be charged for breaking in.I have never seen sheathing done that way in my lifetime.
Why cut through a wall, there are already big holes in the wall called doors and windows.

Can you tell me where code permits fiberboard for sheathing? I'm not saying there are none just asking if you can tell me.That's why I didn't say OSB or Ply.
The alarm wakes you so you can let put the scream! I see no disavantages of the alarm. I cant see intruders get agitated by one. Dosen't happen. Will the alarm help, qho knows, but it cant hurt.Would this be more effective (given peoples' tendency to ignore alarms because they are often giving false positives) than a blood-curdling scream? I guess if you're not at your campsite, sure... it may deter someone. But "improved" campsites rarely have any property crime against other campers. And dispersed camping -- nobody's going to hear it anyway.

I found some info on structural fiberboard but looking at the specs it doesn't look like it will cut with a knife.
I have never seen that used. Couldn't use it in the northeast. If that stuff is used then I concede. You could cut through it.I think it's been largely phased out, but a lot of 50s-80s houses around here (including my own, built in 1980, and the house I grew up in, built in 1969) used it.
I'm talking about stuff like this:
