You lose the point anytime you (1) hit the ball out, (2) in the net, (3) double fault or (4) Boomer doesn’t see the ball bounce in the singles court within a reasonable amount of time. The camera is wide-angle, but will not detect a bounce if you hit the ball way out of the singles court. The system is programmed to ignore bounces outside the alleys, for example, to reject balls bouncing on adjacent courts. If you hit a ball that bounces 15 deep of the back line, it will “timeout” for the same reason.
