I've been using cameras for the past 5 years. A military buddy bought the first one for me as a departing gift when he left for another assignment. That one is a Simons brand and it takes the BEST pictures... then my wife bought me a second, a Moultrie to cover two places at the same time.
They are great to see what's living in the areas you plan to hunt or what types and sizes of bucks/bulls are in your shed hunting areas. Its really cool to have a pic of the buck and later find his shed(s) to match up with the pictures.
I put them on trees about waist high, pointing straight down game trails in thicker forested areas to see what type of game is using the trail. The camera captures them coming and going. I've gotten photos of turkeys, squirrels, crows/ravens, deer, coyotes... but no photos of any elk yet. I prefer the still photos over videos so I do not used that feature.
I have not placed them on fence posts or in open fields cause in my area they'll probably walk away! I've not had any problems with batteries dying or running out of memory on the SD cards, and I've put them out in Jan/Feb in freezing temps. Some years the batteries have lasted for as long as 3 months.
I have my cameras set to record date/time/temp and most photos are between 6am to 9am and again 3pm to 6pm, mine also use Inf-Red and capture a few photos at about 10pm to 12am midnight but not too many.
