We purchased 2, the Santa Fe and waiting on the UP from Trainworld, the Santa Fe is crystal clear, yet a friend purchased the same unit and the window in front of the camera was flawed, once he removed the window the picture was even crisper than our unit. It seems to be a random number of the cabooses with bad windows in them. I am hoping the UP is good out of the box, as the wiring is a bear to keep sorted when remove the shell.
