Pretty sure @stevo_com bought one. Idk if it's waterproof, but I'd have thought that would be the first move, then at least you have a gauge of whether someones just going to dig it all up anyway.
I got a cheap usb one off eBay. Have to use my laptop now as my phone is USB C, so it's a bit of a faff. I very much doubt it's waterproof. Main handy use has been locating joists through down lighter holes. And looking up my nose, natch.
How much is a cheap camera these days?
