Have run non cell cams for close to 20 years starting with the big 8D cell battery ones that lasted a month to the current models that last many months on 8AAs. Most our cam use has been on our property for keeping an eye in the local critters as well as security on the place and our cabin. I do use them around the house from time to time to see who is pulling up to our gate, or watching the bird pens or just to see when the deer, bear, coyotes and raccoons are active.
There is lots of good info above, I'll add a few.

Grass or a branch that blows into the view of the camera can put a ton of pics on your camera in no time.
Location with direct sun can and likely will be an issue if not considered.
Bait is great but be sure it is mostly used by your target critter (a bear will eat a bag of wet cob in a day!)
Apples are great but not when range cows are around, bears love them too and 10 gallons goes really quick.
Get the biggest SD card your camera can take, extra pics can be deleted but missed pic can never be captured!
All our cams are at least out of normal mans reach, the cone or branch behind the cam for aim is cheap and works great.
NEVER eat bacon before putting up cams or swapping cards (bears love bacon grease) cams disappear, lol.
Natural travel paths have been better for us than random camera placing.
always double check the new SD card is installed and battery has enough juice.
Cold weather will burn batteries faster!
Ensure the seal is good around the battery pack as moisture helps corrosion.
Clean the lens on the cam now and then, recommend something scent free.
If your cam is not where you left it look around really well, may have removed by and animal (see bacon grease comment)
TEST EVERY CAM AROUND THE HOUSE BEFORE TAKING TO THE WOODS!
We have had great luck with Moultrie, Bushnell and Browning cams. Not a fan of Stealth cams but they are a great deal if theft is a concern.
