I get about 700 pics off mine in Macon county but I get a lot of daytime also,it will cut down to about 400 when it gets cold and the nights are longer.ive tried the lithium and copper tops I can’t tell any difference,I read lithium batteries help. Can you program them to take pics at certain times of a day? How long do batteries last if they are taking every picture? Can they only ID certain types of game?
