Summary: This was my first video camera. It's OK but the 720p LifeCam Cinema is much better and well worth its higher price. The video quality on this camera is OK in good light conditions but poor in lower light - the Cinema has a much better image (at the same resolution), especially at low light levels. I haven't tried any of the messenger functions so I can't comment there. It's an OK first camera but you should upgrade if you really want to do videos.
Summary: I'm really glad I got this web-cam years after its release. The installation was, for the most part, a breeze. The disc wouldn't load on Windows 7 64bit as it was blocked. That's OK, it started searching for the solution. In the meantime I Googled it myself and found the latest software. About 10 seconds afterwards the Microsoft service found their solution, but one version previous the one I found. The video quality is fairly atrocious.
Summary: Easy to install and excellent picture. Adjustable focus by turning the lens. Wide angle view good for conference room use. I had difficulty getting it to work with Skype. Logitech's cam much easier to use and comes up with no problem. The size is bulky for carrying around in my backpack. And there's an annoying button on the top that tries to open MS Live each time you push it by mistake. A manual zoom feature would be nice.
Summary: With all the hype of video conferencing I finally purchased a web cam with mic built in. I was disapointed with the Mircrosoft due to everyone complaining that I cut out on vocals when I video conference on Skype. Haven't had a chance yet to try the cam out on a different service but will try it out on differnt ones, maybe Yahoo!'s service or something.
