About 6 months ago I hung an Arlo wireless camera above my door with a very narrow field of view to only cover my own area, at 1245am this morning it caught an individual walking from W-E along our hangar rows talking on a cell phone, it appears they tested my door handle before heading down the rest of the row, where they went out of view. Because of the recording the police and the airport are taking it very seriously.
I had been operating in stealth mode, just to see if anyone was around, now I'm switching to deterrence mode so the spotlight will come on, get a better recording and let them know they're being observed. I've also talked with my hangar neighbors and they've asked me to expand the field of coverage as wide as possible, they'll accept any loss of privacy. As others have said, you're just trying to get them to go somewhere else, and get a recording for the police and insurance.
For anyone who wants to copy me, I'm running a T-mobile 5G home internet thingy https://www.t-mobile.com/home-internet from my t-mobile cell phone plan, $30/month with pretty good speed, fast enough that even with the doors closed I can stream old movies/tech videos/music, plus a spare Arlo wireless camera from my home security system with a month of storage of past videos. If anyone wants advice let me know, or if you have a better way I'm interested in learning.
