centrios webcam driver

Solution
That brand is actually made by Sonix. Check out their website at

This one may work as well....

if you can't find it through the website, and the second link doesn't work then try emailing them for support.
The device manufacturer (if you know who it is) will have drivers on it's website. I realise that's not going to be easy with a device that has such an obscure name, even Google doesn't list it.

You may have to bite the bullet and by one made by a well-known manufacturer (eg Logitech, Creative, Microsoft). No problem finding their websites and driver downloads.
