007Blacktail: Any time you get rain, snow or wind which causes grass, leaves or branches to move, this will cause any trail camera to trigger. Some brands of cameras have a sensitivity switch. This could be set to a lower setting. The cameras with this feature have: low, medium and high. Default is medium. I have the Moultrie D55-IR and encounter the same as you are. Grass or branches could be removed in some situations, but not rain or falling snow. I also have Spy Point IRB, and the 2009 Bushnell Trophy Trail cameras. These all do the same. Trail cameras are designed to trigger upon motion.
