How about a nice way to look at them? I was thinking one of these or one of these.
It looks like he is using a PCB microscope with a built in camera. You can pick up a similar one with a 5MP camera for around $700 in the US. You might be able to find one cheaper on ebay or Aliexpress.
Edit: Just checked the video again. It looks like he bought an SZM but I cannot tell which model. You can see the HDMI port on the camera when she is putting it together in the shop so the top device is definitely a camera of some sort using the third optic port. The camera doesn't look like one I've seen on them before so it may be a aftermarket item.
Pretty sure this is it minus the camera.
