So, IÂ´ve been getting a lot of PMs and Mails about suitable Cameras for Multitouch Setups.
I had a chance to test some through my University, so I would like to share my findings.
1. Phillips SPC 900NC
The “beginner” Camera.
- USB Connection
- Winodws only (more on that later)
- 640×480 resolution max, 90fps max
- Sells for about 58 Euro
Removing the stock Lens:
Removing the lens is really easy, just remove the silver ring that is attached to the Lens.
You can then insert a new, M12 lens without IR filter. Takes about 5min. Detailed instructions

Other than advertised, the Phillips doensnÂ´t deliver 90fps at a 640 resolution, it somehow
compresses the video stream, to make it appear that way. Its probably sending each frame
three times or something. Not sure exactly how, there has been quite soem discussion on the forums
about that. Setting the Camera to its highest resolution and maximum framerate uses a lot of
resources, so my fans start to rev up pretty fast. So you will be using a lot of cpu power, which
doesnÂ´t fell right for me. IR sensitivity is good, and it should be enough for most setups, I believe.
2. Unibrain Fire-i
- Firewire interface
- 30fps at 640x 480 resoltuion
- about 90 Euros (color), or 129 Euros (B/W version)
Removing the Stock Lens:
No problems here, because you can just screw a M12 Lens right on to it.
