Pros
Pro High resolution and great detail
The Logitech BRIO webcam can stream 4K quality video(4096 x 2160) at 30fps (frames per second), full high definition video (1920 x 1080) at 30fps or 60fps, and 720p video(1280 x 720) at 30fps, 60fps or 90fps. This lets you choose between streaming 4K video where possible, or higher fps video where 4K is not supported.
Pro Infrared facial recognition focuses on You
The infrared facial recognition system focuses the camera on your face at all times so you will never look blurry/out of focus.
This same face recognition is used by Windows Hello, which lets you log into your PC by just showing your face to the camera.
Cons
Con Expensive webcam with very little practical use
Most software does not allow 4K streaming, making this webcam useless. Even if the software does support 4K streaming, then most people viewing your webcam picture do not own a 4K resolution screen and will not benefit from that resolution.
