For your consideration ...
We're currently dealing with chronic theft of gasoline, gas tanks, and batteries, from our boats docked in White Neck Creek. I put up a game camera in what I thought was a concealed spot but they stole that too!
Should use one of those cameras that stream the recording to a server of your choice and phone at the same time, so at least you'll see them stealing it. : )
Similarly, you could put three or more cameras out. Place one, the cheaper of them, in an area that is pretty much guaranteed to be seen by the criminal mind, the other two, hidden and well camouflaged. Most idiots out there, thinking after they found "the one", won't think of looking for anymore in that general vicinity.
Make sure to salt the premises with good looking stealable things such as with some old gas cans filled with water, (they won't open them to check if it is gas. And as an added bonus, they just might put all that water in their cars.), old dead unable-to-hold-a-charge-anymore batteries, shined up pretty like, you were going to get rid of anyway, (with some air tags attached and hidden to find their locations after the steal), etc. to entice them into returning and taking them.
Should also be able to see and record them during the day for help as well for use in later identification. Since these rectums love to scout out areas such a marina's in daylight while pretending to be doing something else such as fishing or scooping crabs off pilings, etc..
If'in ya need'in the funds for such a security mission, you could always reduce the Christmas bonus for
@stgislander under the guise of company revenue being down this year. Pretty sure he's been slacking a bit while you've been away in places such a Norway anyway. He'll understand, if not feeling outright guilty about making the business suffer in your absence.
