He is using a so-called "360 camera" on the long line, and he mentions this at the beginning of the video. There are quite a few "action cam's" on the market now that, by using two 180 degree spherical field-of-view lenses back to back, capture a 360 degree view in both azimuth and elevation. Perhaps the most famous examples are the GoPro Fusion and the GoPro Max, but there are many others. One then processes the captured video through the camera software, typically on a PC, to obtain whatever view one wants. The software will allow panning, zooming, stabilization, and other effects. The GoPro software even includes "selfie-stick removal", so if you hang the camera out at the end of a stick it will magically remove the stick from the video and make it appear as if the camera is floating in space. Using video editing software you can even mix together multiple, simultaneous views. It's really cool technology that is surprisingly mainstream at this point.
