I want to buy one of these. A 200 year old graveyard that sits on my old summer camp is constantly vandalized in the off season. It’s pretty much been decimated over the past few decades. Would love this.
Edit: two day battery life wouldn’t cut it for my application.
A well placed/camouflaged trail cam or two might work.
One that’s activated by motion detection like the ones they use for tracking endangered species?
