Check to ensure that you have
drawn at least one target zone
you are in "Shooting" mode, and
the shot timer is started.

If LASR X is not reporting the impacts, it cannot see them.
If the target is too far away from the camera, then the laser impacts may be too dim/degraded to be seen. Moving your camera closer or using the higher resolution option (only recommended on computers) can alleviate this issue.
The laser impact must be brighter than the brightest ambient spot in each target zone. If a target zone has a dark area and a very bright area within it, it can cause shots in the darker area not to be detected, as they simply aren't getting bright enough to be brighter than the bright spot. Reducing your overall lighting to reduce relative brightness, adjusting your target zone to exclude a bright area, or changing your targets to something with more even brightness is a potential solution to this issue.
Unusually dim lasers from low-quality devices or devices whose batteries are running low will also cause those laser impacts to be harder to see, and LASR X may miss them.
Remember that the issue could be a combination of 2 or more of the issues above, so your set-up may require some trial and error. If you are getting frustrated, please contact us for assistance. We have found that phone and tablet cameras tend to not always adjust well for LASR X's needs and that external webcams tend to do a better job. Overall, a lower-light area is less likely to be problematic as it makes the laser impact much more "brighter" and easier to detect (relative to the ambient lighting).
