My stealth cam is great. Its a far cry better over the Moultrie I first purchased. But I did also find my 1st couple rolls of film were blanks with the Stealth. 1st I too used 800speed film like I did in the Moultrie. 800speed just doesn't seem to function right in the Stealth. Kodak 400 works great. I also notice a small branch was triggering my Stealth. Make sure all small branches, leaves, grass blades, and such are out of range & view to trigger your camera. If neither of those does it, then guess you got a faulty one.
