philips Webcam SPC900NC driver

hi,

(This is my first post in this forum then i hope to post in the good place)

for my project, i would like to use tracking algorithm, then i need a fast webcam with good image quality. I thought to buy the Philips SPC900NC with ccd sensor.
I read some posts in this forum about webcam drivers and i try to go to dolphin.de website but it doesn’t work…
Before i buy this (expansive) product i would like to know if the existing drivers (for old models) is working for new models (with usb2 compatibility for example).
Or any advice about webcam choice.
