Today is a hot one here in Ohio. Hot and Sunny. Nevertheless, my camera has been in the shade so far today but i walked by it earlier this afternoon and noticed it was making a strange sound. The motors should not be working in it. It was standing stationary. transmitting wifi only. still have a great picture and all. If anybody has any idea why it would be making a noise like this i would be interested in hearing about it. its a chirping kind of sound almost.
