Do you have your camera on a feeder or trail, also check to see if it recorded any events, if it has recorded any events that means it has had activity in front of it but not record the pics for some reason, also make sure it is set on "live action mode" and not "disabled". I put my camera out in June and we have had some record setting temps but I still get alot of pics, especially of a night, one other thing to check, go into "camera set-up" and see what you have the sensitivity level set on, if its set to low that might be your problem especially as hot as its been. One other thing when you check the camera to see if it has any recorded pictures does it say "0" pictures recorded? If it says you have some recorded but all you see is blackit may be your flash is turned off or not working. You need to bring it in the house sit it up in a dark room, give it a few minutes to adjust to the dark then walk in front of it, see what it does, it should record an event and take your picture if its working right. let me know what you find out. Also , you may try taking the batteries out of it and reprogram it again, are you using a compact flash card or the camera itself to record on?
