Your problem may be due to the temperature. I don't know where you're from, but we have been experiencing some abnormally high temperatures here in Michigan. The optimal temperature for Cuddeback performance is between 30-75 degrees where you can expect the Cuddeback to sense motion up to 50 feet. At 80 degrees the sensor range drops to 20 feet. Performance might be diminished even more in higher temperatures, I don't know. This is according to their website. I remember that quite a few years ago with a different camera, I didn't have any pictures on my trailcams during the summer months, but the camera worked fine the rest of the year. Don't know for sure if this is your problem, but it might help explain it. So if they begin to function much better when it cools down, you will know for sure.
