I know the Logitech C905 Logitech C905 Portable Webcam installed only stationary and covered in a unit for documentation purposes. The installation on an older PC with a Pentium 4, 2.5 GB of RAM and Windows XP SP3, and the connection with an approximately 2-meter USB cable ran smoothly. It is operated remotely with Logitech Camera Driver 1.10.1113.0 and documentation software for image evidence. For photos, the automatic exposure has been shut down and all set manually.
What convinced me since the very sharp photos in the used constant resolution 1600 x 1200. Even the smallest labels are displayed sharply and is very readable. It serves its purpose perfectly.
This is why I ended up here looking for more information on this model and would therefore buy me at any time for at home.
