For me they are off season fun for the whole family to see what is on the property.
I am trying to hold a lot of does on my places and it lets me know if what I am doing is working or not. I have gotten to know what deer actually live on the properties I hunt and what ones travel through. I have a doe with a scar on her knee that has lived at one woods the past seven years raising fawns.
In spring and summer I get a bunch of buck pics and it lets me know what's in the neighborhood and how they are growing but they almost vanish late summer early fall until rut. And it's fun to see the bucks mature from year to year.
Cameras also let you know what time of day the deer are in the area and it has also worked for me in spring on turkeys.
I definitely get some traveling cruising bucks that I have never seen any other time of year stop in during rut..and that is why I like to try and keep does on my places as "buck bait" for rut. Does seem to be more predictable and homebodies way more than bucks.
Also get a bunch of other wildlife pics too..turkeys, fox,eagles, owls, hawks, yotes, mink and bunnies along with thousands of squirrel, bird and **** pics. And usually once or twice a year some scumbag trespasser who is to dumb to stay away from the camera and off my property.
