Camera Threshold is used to isolate the laser light of a training weapon. This is similar to the Camera Threshold setting in Setup mode used during calibration. The difference is that this setting affects Practice and Course modes. You should not need to change the default value of 150, however, if you find your system generating phantom shots , you can try to increase the Camera Threshold setting in small increments- such as shots that occur when you do not pull the trigger or multiple shots being fired when you pull the trigger once - you can adjust the Camera Threshold setting.
If the system generates shots when you do not pull the trigger, move the Camera Threshold setting higher.
Move the Camera Threshold setting lower if the system generates two or more shots with each trigger pull. This may happen if you are using a recoil-enabled gun.
