its off and on where i have my camera out, i put it out one night because alot of the deer were moving at night there, and after about a day and a half, the counter read 42. It is set for 2 pictures every 6 minutes when it gets activated though. Anyways, i swapped the film and took the other to get developed and went out there about 2 days later and the counter only read 8. But then i checked it the next day and it was in the 30s again.....Those damn deer can be tricky.
