All 3 of my cameras are takeing pictures right now with nothing in them I can see that the temp is hot and that there was a cloud gone over the sky and it triggered the camera, is this what they call ambient heat, It is in the 90's when my cameras do this, 2 are heat triggered moutries and the other is a motion sensored, I know it is not animals and they are missing them.

Same here, I've had lots of pics of nothingness!! I need new cams because I'm gettin pics of the tail end of a deer as it passes by. Any recommendations?

Sounds like your problem is just slow trigger speed, try setting up over a feeder or mineral lick or setting up down the length of the trail so the deer are in the view longer. If your looking for a new camera try www.chasingame.com for some ideas about faster trigger speed cameras and price ranges. My cameras are acting up now because of the heat, something to do with ambient heat I think?

nobody has any issues with heat causing false triggers!
