I'll tell you the truth, I couldn't find the camera mentioned, I looked for it in Microsoft's website (for compatibility check) and also in Logitech's website, and again with no success.
If you can give me another name of the product that you want/link to it.
I'm glad to help you, but In generally you can go at any time to this website that checks the compatibility of a software/hardware with Windows 7, http://www.microsoft.com/windows/compatibility/windows-7/en-us/default.aspx
to save time. If you want you can continue posting your questions and I'll be glad to answer them.
Next time that you ask for compatibility issues mention the version of Windows that you own 32/64 bit.
About the recommendation; Where are you from? in order to focus the searching area of the product.
