Logitech C270 worked quite good w/o ir filter removal. Just a piece of floppy filter in front of the lense.
3 point hat 30 FPS 0 Jitter RGB24 640x480 i420 I did a stupid thing though. As I wanted perfection I tried to remove the ir filter which is located on the board and not in the lense cap. Tried to be careful, heated the board with a hair dryer to losen the glue and cut the edges followed the advice of JoshMC: http://publiclaboratory.org/notes/joshmc/10-12-2012/webcam-conversion-near-infrared Eventually I think I destroyed the cam  The cam now sees only black space, whatever I do. I ordered a new one. I want to ask 2 questions: 1. Does anyone counter the same problem? Is there anyway to fix the cam? I saw that nothing was destroyed on the board 2. With my new cam. is there another easier way to remove the ir filter without damaging the CCD? tnx in advance |

Bought an old A4 Tech PK-130MG (picture below) arround €20... yeah I know a little expensive for an old webcam but really cheap for a tracking system
 and it´s working great in native resolution of 352*288px @ 45 fps in RGB 24 with a wide angle angle of 72 degrees. No IR filter removed; only a piece of photograph film to block visible light. The trick is to start the camera in FT with the lens covered to obtain constant 45 fps, really happy with it, Free-Track is amazing [even with my improvised 3point clip with IR leds]. How to remove IR filter for this webcam here: http://forum.free-track.net/index.php?showtopic=4640 Photos of the 3point clip here: http://forum.free-track.net/index.php?showtopic=466&message=19977 |

Hi.
Just acquired Esperanza TC102  pros: - its cheap, cost ~7$ new. - removable lens - IR filter is very easy to remove, just unscrew lens and use a needle to remove filter - mic (not tested) cons: - camera is very light so I had to use duckt tape to stick it on tv. - cabel is very short ~120cm - it has 6 blinding leds without twilight sensor. you have to remove them or use electrical tape. Camera working via splitcam in 28fps 640x480. Tested with ETS2 demo and its working well. This is my first encounter with freetrack so I have to find the appropriate settings for the games but for now I'm happy ps. In "Your point model constructions" topic I posted a video of my freetrack construction. |

Creative Webcam Vista/Live! Cam Chat (VF0330)
 - couldn't get 30FPS to work in FreeTrack - can't remove the IR filter, but it works alright without it  Looks like this in a dark room, with 3 SFH485p LEDs at 60mA. There's an option to select 30FPS at 320x240. I don't know if I'm doing something wrong, but it won't go higher than 17FPS in FreeTrack.  |

reply to justonce01,
did you do the brightlight trick?It goes like this: remove your daylightfilter, Turn on AE, shine with a bright light into the webcam.Now you will see the fps go up, turn off AE and now your fps will stay on 30fps. I use a ms vx3000 webcam, without doing this I have the same problem.  What is that button auto Tuning? |
Installed the latest drivers from the Creative website and tried connecting it to the USB ports directly on the mobo, but it still won't go above 17FPS.
Thanks for the tip, I tried the autoexposure/light trick and it didn't work properly. It shows 30FPS, but I'm getting a massive delay between actual head movements and the camera (1 second). Which auto tuning button do you mean? |
