Help answer the question about Focusing Zoom
Looking for webcam with 5MP or more true not interpolated. With optical zoom, focus, exposure, gain.?
Basically Focusing Zoom the webcam will need to have 5 Mega pixels or better resolution (true not interpolated). Also it should have an optical zoom. It should have computer controls for zoom, exposure, gain and auto focus. Thanks,
