Wait on him, take pics of the incident With your cell phone or better a video, make sure he comes too you on your property, record the exchange, then immediatly call the D.N.R. AND HAVE THE ***** ARRESTED, YOU DID SAY HE THREATEN TOO SHOOT YOU RIGHT. PRESS CHARGES FOR TRESPASSING AND TERRORISTIC THREATS. Or wait till he goes somewhere one day and saw the ba@@@@s tree stand down.
Careful, he may have cameras as well.....
NO, his having a camera will not be an issue, so long as you're not breaking the law. I'd just tell him right off when you see him next that you're video taping him, and if he doesn't wish to be video and audio recorded, he can leave with his mouth closed, but remaining and speaking with you is consent. Be sure the cameras are running first so that your warning is captured on the video.
You will need some trail cameras too. He will mess with your area if he gets too frustrated. I'd also put up "No Hunting" signs on your side of the property facing his....,
The bit about "my shooting lane" is a huge giveaway..., this is the same type of person that thinks the space in front of their home on a public street is "theirs". The other commenters are correct, he has no business tossing a shot over your boundary.
What he's likely to do, is make false complaints on you to force you to stop using the land for hunting.
