When it's hot, maybe try a water spot or a trail to a water spot. If you have a hot trail that you're aware of then try it there.
Just gotta move it around until you start getting pictures. I'd leave it at least a week in one spot before moving it but that's just me.
I haven't gotten any deer pics on my new cam I put out two weeks ago but I'm getting foxes and yotes so I'm leavin it for now.
