Can the DWL-P50 power-over-ethernet adapter be used to supply power to the network camera DCS-932L? The DWL-P50 supplies 5V 2.5A. The external transformer that comes with the DCS-932L supplies 5V 1.2A. And the back of the camera itself is also marked 5V 1.2A. Can the camera "ignored" the extra amps? Thanks, Tom
