well to be honest, just cause your camera isn't getting pic's doesn't mean deer are not using, or living on your property
a deer can be very elusive to camera's
as many camera's suck too, and never see.take a pic of what walks by

the best advice if your planning on long term hunting this lands is to improve them, plant fruit trees, add a food plot
do some timber cutting, to allow new growth to come up, plant tree's like oaks, beech nut, , good browse and future nuts

deer need cover/safety, water and food to live
if you have all this, you will have deer

a bait pile like a food plot will feed all critters
some things will attract more of some species, but its the nature of the beast when you dump out or plant food

your land has to have what deer want or deer won't have reason to be there
good news is most places have something deer like, bad thing is if lands about you have better offerings, they will be there instead of your lands most times!
like they say, you build it they will come!
