I have some big bucks on my property. Cameras are getting them but just barely, what can i use to get them in closer to the camera?

you could try to move the camera closer to where they are coming through?

You can put a bait pile of some sort of deer candy or deer food or cmere deer or a salt lick or a trophy rock, right in front of your camera.
Also make sure you have your camera in the right place like the earlier post said.
