If you're dealing with pressured deer, tending your trail cams every 3-4 days, or even on a weekly basis, can educate the deer to your presence and possibly push away mature deer from the area.
I know it's fun and the anticipation runs high when you setup in a honeyhole, but to avoid pressuring the deer too much, you should follow these basic rules;
try to swap SD cards at your camera site on a rainy afternoon;
wear knee-high rubber boots too and from your trail cam site;
wear latex gloves to handle camera / touching vegetation, etc...
SPARSELY use a scent cover product or a carbon activated scent eliminator should you come into contact with vegetation and / or trail cams.
I know this sounds pretty radical, but if you're deer herd is on high alert, it is precautious steps that are worth following.
I had a mini-herd of deer wintering in my backyard last year, for these unpressured / post rut deer, it did not matter if I checked my cam on a daily basis with foul scented clothing.
Also, as others have mentioned, you might be just experiencing what is most often called a ''lull'' period of low activity. Remember also that mineral licks are not being hit as much as summer progresses. They seem to re-hit in early fall.
Good luck with your setup.
