Very disappointed with this webcam received there about a week. I bought it to install on a PC with Windows 7 Home Premium, it appears that it is not compatible, and the facility has stopped all it took my system restart. In addition there is no explanatory installation instructions except a mini DVD or leaflet for foncxtionnement and settings. We can not expect either to something extraordinary at this price. Installed on Windows XP pack 3, it seems to work normally except as said above settings. I do not recommend it.
