      I finally was able to get the h camera and things have defiantly improved. It seemed to work good in the protee courses. However, when I tried to use it on tgc I was having all sorts of issues with mis-reads and shots defiantly going left again. I am also get an occasional big misread with protee course as well. Any ideas what the problem might be? Thanks.

        Come on Jonny, you're going to have to give us more info than that. Post screen shots.

          I figured out my problem...if the cameras are working fine at 320 x 240 is it worth it to try and still change to 640 x 480? Does this improve accuracy ?

            It looks like you are using the wide angle lens. To use 640X480, you'll to use the regular lenses or my recommended lenses. My recommended lenses make the image brighter and little clear, which helps with ball detection. But if they're working fine, leave it.

              I'm using the standard camera lenses that came with the base pack 2. I found setting the H-cam to 640x480 and leaving the V-cam at 320x240 worked best for me. The V-cam had too much of a fisheye look with the stock lense at 640x480 but works perfectly with the default resolution. 320x240 for the H-cam had too small of a viewing area. Setting it to 640x480 widened it's FoV and helped it pick up the ball streak better.

                I just noticed that in my settings file the frame rate for both vcam and hcam are 125 but when I look at the screen caps I typically see around 30-40 fps. This seems like a contradiction? Perhaps it doesn't matter?

                  Oddly, my hcam reads 640/480 in flycap and the video feed shows the same.......BUT the interface will keep defaulting to 320/240.....tried to save/reboot several times but it doesn't stick?? FYI, I did manage to get the frame rate down manually and it saved.

                    change the camera settings by using Alt e, then change them manually in there. Save close and reopen. Should work

                      I've got my subfloor in and starting to work on a permanent setup and I'm running into a focus issue with the v-cam. I'd like to mount it on the left side of the room to cut down on detection issues for right handed golfers AND keep it near the wall. The problem is that I can't focus even close to infinity past about 4mm-4.5mm on the zoom (I have the 3.5mm-8mm zoom) and maintain focus at the ball position. The end result is a rather wide FOV. Will this work or do I need to pick up another lens or move the camera closer?

                      Also, is it aimed more or less how it needs to be and about the correct distance forward of the ball position? How do you get the screenshots with no golfer in it whatsoever and keep the ball in view at all times?

                      ...And for the other miscellaneous things wrong in the screenshot - I haven't even tried to hit a ball yet in this setup and I"m still a little ways away from it. Need to paint the floor black (temporary until turf is here) and I've got a curtain coming to cover the window well and give a nice dark backdrop for the v-cam. ...And its not level yet either.

                        FOV seems to be ok, but I can't get the camera to work with 2 16' active USB extensions daisy chained together. Is there a way to get a cable longer than 30-ish feet?

                            Swingsense is out of stock on the hcam, but they did let me know that you can buy them directly from here:

                            It doesn't come with a lense or the usb extension cable, but that's ok if you're going with Zmax's upgrade anyway. Hope this helps someone.

                              Thanks for the heads up iskuo.

                              Keep in mind the new camera above uses a CS type lens, which uses a bigger mount. You will have to get a CS type lens for it. Or If using my recommended lens, you will needed a CS to M12 adapter.
