The Logitech Brio 4K is a 4K webcam with autofocus, adjustable field of view and infrared support for platform authentication. It covers more of the range than the Elgato Facecam: more resolution, an autofocus mechanism, and a sensor feature that the Facecam does not record at all.
This review is built from the specifications recorded against the product, each with its source and a verification state that is currently partial. We have not handled this camera, so there is nothing here about image quality, a focus distance or a low light result. The recorded resolution, focus mode, field of view and infrared support are what this page works through.
What 4K buys and what it costs
The recorded resolution is up to 4K at 30 fps, and 1080p at 60 fps. The two figures sit together in one line, and they describe two different jobs. A 60 fps workflow runs at 1080p rather than at 4K, so the resolution you buy for is the resolution you get when you are also chasing smooth motion.
That is the bargain of a 4K webcam, and it is why the Elgato Facecam can be the better answer for a 1080p 60 stream.
Autofocus
The recorded focus is Autofocus. This is the specification that changes day to day behaviour, because the camera can follow a subject rather than hold a single focal plane. For a fixed desk and a fixed seat, autofocus solves a problem you would not have had. For a camera that moves between rooms, or a presenter who stands up, it removes the need to reframe.
The Facecam records a fixed-focus prime lens, which is the opposite decision and a defensible one.
Infrared support
The recorded infrared support value is Yes, and infrared authentication support is the only entry in the recorded feature list. This is the feature with the narrowest audience and the clearest use: signing in to a computer that expects an infrared camera to confirm that a real person is present. No other webcam in the catalogue records it.
Field of view
The recorded field of view is Adjustable, without the software qualifier that the Facecam records. In practice that means framing can be changed, though the recorded data does not say how much of the range is available.
Who this is for
The Brio suits someone who needs 4K capture for a high resolution recording, or who signs in to a machine with infrared authentication, and who is willing to pay for it. It is a poor fit for a buyer who wants a manual exposure workflow, because no manual exposure control is recorded here, and for a 1080p 60 stream that wants to stay at 1080p.
Where the alternative sits
The Elgato Facecam is the alternative: 1080p at 60 fps, a fixed-focus prime lens, a field of view adjustable in software, manual exposure control and a monitor mount with a tripod thread. Choose the Brio for resolution range, autofocus and infrared. Choose the Facecam for a manually controlled 1080p frame.
