Has anyone ever used on of these for perimeter safety?

I've seen then near Marijuana grows.

I'd think these would be trip rather often by animals.

They are set into the ground and a wire is run triggering it.

Really cool idea, but I have so much wildlife around here they'd be going off every night.
They would work well in the city though
