Cameras do not pick up on ultraviolet light, which is actually what causes issues to develop when viewing welding.
Is arc welding bad for your eyes?
Exposure to infrared light can heat the lens of the eye and produce cataracts over the long term. Visible light from welding processes is very bright and can overwhelm the ability of the iris of the eye to close sufficiently and rapidly enough to limit the brightness of the light reaching the retina.

Why does looking at an arc weld hurt your eyes?
When you look at an arc weld or the sun, the thing that hurts your eyes is the ultraviolet radiation that is in sunlight and the arc of the weld.
