I have one DCS-2132L and was planning to buy many more of them. However I am having a critical showstopper issue with the one I am testing. It is in a room and when the light is turned off and the door is closed it is obviously dark and the IR led comes. If left overnight and checked in the morning, every time the camera is found locked in IR mode, light does not cause it to leave this mode, and the status LED is off (neither red nor green). It requires a power cycle to restore it to service.
This is obviously completely unacceptable and renders this camera useless. I was planning on getting several dozen or more of this but without a solution I won't be buying anymore. I have contacted support as well but I am wondering if anyone else is having this same problem.
