I have several Wildgame IR cameras. I've noticed the night pictures are mostly all black, even if the deer is standing three feet in front of the camera. The day pictures look perfect. The batteries read half charge. Do they need a full charge to get better night pictures? I wouldn't think this would make that much of a difference on a IR camera. The cameras aren't even a year old. Would a total memory reset take care of this problem? When they were new the night pictures were very clear.
