Moultrie I-40 vs Wildgame IR4
Both of these trail cameras use the same 4MP image sensor and have 1 year warranty. Wildgame IR4 has more either internal and external memory, it also takes up to 30 seconds video in AVI file. Moultrie I-40 has longer flash range up to 50 feet, and it uses 6 D-cell batteries that make it longer use up to 150 days. While IR4 use 4 C-cell batteries for only 4 weeks works. If you serious in night photos, I recommend Game Spy I-40. If you want to capture in video, I recommend IR4.
