==Consumer | I just bought C930e. To my surprise unlike my old c920 it does not have h264 hardware encoding. Using mjpeg makes video more noisy. In the internet people are reporting that at some point logitech removed this feature from their products. So basically new C9XX can be different product than old C9XX. | ||

*Feature removal | |||
*False advertising | |||
H264 encoding feature removed at some point. MJPEG has a lower quality and lots of noise. Uncompressed stream does not handle 30fps in 1920x1080. | |||
The model numbers were not changed to reflect degradation. | |||
The website still claims it has this capability. | |||
