I pick up my laser tomorrow (Boss LS1416) and want to order a camera

I don’t know the first thing about the laser yet, but I’m hoping there is a standard camera setup that people use with that laser. What camera will I need to order? Is one FOV better than another for that model? I’ve seen a couple of videos of people installing cameras…is it typical for people to leave the top door open on the laser while cutting, or is it open only for alignment of the material?
