I use Moultries. I buy from Native Outdoors or Rogers sporting goods. They also have a bear box(metal security enclosure).
I leave my Moultries out all year long and only change batteries when they get to less than 20% charge which is about twice a year. I recently just got my 1st bobcat picture and have them placed to now mark my turkey patterns I need.
I just checked on camera I have not looked at since Dec 20th. It has over 3,000 pictures.
