How do those systems stop hair or clothing from getting sucked into the spinning bits? Those two modes have always been the more dangerous ones for spinning tools.
This is the machine I was running like 20 minutes before posting that comment. https://www.youtube.com/watch?v=7AuwwPdBSf8
I have no idea why the people in that video cut a hole in their door. Seems like a really stupid idea to me. But you can see in a normal machine that someone hasn't modified to be more dangerous you can't get to the the spiny sharp bits.
So in order to sell that machine to me I would require a safety compliant door. My guess is a new door would be around $2800. That is an expensive hole.
What I know that you don't is that that machine is sold with a camera as an additional option. So there is already a place inside for mounting a camera. They would just need to make their own mount. Otherwise if I was just filming a demo to sell the machine I would override the door closed safety interlocks and film with the door open temporarily.
