1. Be patient and wait until the rut compels them to travel more.
or
2. get closer to their bed. Its likely they do move a little during shooting hours

Assuming your getting this information from cameras put them on video and get a better idea of their coming/going and get closer but that is not usually an easy or quick process and you risk spooking them doing it this way but I'd almost guarantee you they are not 100% nocturnal.

I have a camera near a big bucks bed right now and get frequent daylight pictures of him(every check) somebody somewhere on the surrounding properties probably has pictures of him and thinks he only moves in the middle of the night. I also have bucks I only get night pictures of.

If you want to be cautious you will have to guess where they are in the daylight based on videos you get at night and if you know the terrain, deer behavior, primary food sources according to the weather and time of year, and what makes for good bedding.

Start moving your cameras in towards where they are going/coming from until you start getting videos just after/before dark then when the conditions are ideal go in a little further and hunt. Go slow and make sure you don't get in too close before the conditions are right.

Short answer: find their beds

If you get only night pictures your probably to far away which is not always bad if you know enough too guess where to hunt based on that information.

I have several mature bucks I could shoot with in a week if it were deer season right now based on night videos because I know where they are going/coming from but those patterns will change before season opens.
