I know this question maybe tends rather more to IT then automation, but I'll ask it anyway. I already did some plc-projects in abroad, and sometimes I had to discuss a problem over the phone or by mail. Afterwards I considered that If had been at the place of the machine I could have solved the problem within some minutes while now it took me hours, even days. A solution could be to have a camera on site. Do you have experience with some kind of webcams that provide a good sharp view of a part of a machine, that is not too expensive, and that gives fast transmission of views. Are there types that are wireless, so someone can put it where the problem on the machine is?
Thanks
