I bought a braend new camera from walmart speciffically for LASR. spec are attached. So i get the software installed and running and set the taret, calibrated all good. click start and do some test shots but it only picks up 1 out 8 shots. camera is stable on a tripod. I have to hold the laser steady on the target for it to register. I'm using a microsoft surface for my testing. should i try something else? different camera? Any help would be appreciated.
