Lights, Camera, Action!
Here is a tip From Mark Davis at the Kegel Training Center.
One of the most valuable tools an AMF equipped bowling center can have is a camera system and a DVR. At the Kegel Training Center, every pair of lanes has a camera mounted above it.
Using the DVR, you can monitor your machines from a distance and replay any problems that arise.
This also allows you to use diagnostic marks on your machines to help troubleshoot problems that might be too fast for the naked eye.
