I have a M40 that has stopped taking motion detect pics at night. It's been working fine for a couple months then it suddenly stopped taking any pics at night. it takes my pic fine when I walk up during daylight hours. I have since changed batteries and set it to Motion detect and time lapse. It takes the time lapse pics fine day or night but still no motion detect at night. I've evne had deer right in front of the camera on the time lapse but not setting off the motion sensor. Anybody else have this problem?
