Comparing trail camera pictures can be a very simple method of selecting a trail camera. Todays models range in resolution from 1 megapixel all the way up to 6 megapixel infrared cameras. You must determine your own criteria. If you are only scouting your deer lease for bucks, then why do you need a 6MP camera? Can the 4MP deliver what you are looking for? Maybe you can sacrifice 2MP and buy two of the 4MP game cameras and cover more of your property.
