I reset the camera, flashed the firmware again, reset again. So far, so good, although it seems to happen in the afternoon when the sun is shining on the camera. Time will tell. In the meantime I am going to notify D-Link of this issue and arrange for RMA# If the problem goes away I will cancel it. I have never been 100% happy with this camera. I have three DCS-932L's and they haven't made a peep in two years.
