Two products in this catalogue overlap with the Logitech C920s, and they overlap in different ways. The Logitech Brio 4K is the current camera from the same manufacturer, with a higher capture ceiling and infrared support for platform sign-in. The Elgato Facecam is a fixed focus 1080p camera that the manufacturer has discontinued, so it is a reference rather than something to buy.
What the C920s records
The recorded resolution is 1080p at 30 fps, 720p at 30 fps. The recorded field of view angle is 78 degrees diagonal. The recorded focus is autofocus with a glass lens. The recorded built-in microphone is yes, stereo, with a range up to 1 m. The recorded privacy shutter is yes, a physical shutter on the lens, and physical privacy shutter and built-in microphone are in the recorded feature list. The recorded mounting is a universal mounting clip that fits laptops and monitors, and a tripod is not included. The recorded cable is 1.5 m, attached USB-A, and the recorded USB connection is USB-A. The recorded dimensions are 43.3 by 94 by 71 mm including the mounting clip, the recorded weight is 162 g, 5.71 oz, and the recorded operating systems are Windows 8 or later, macOS 10.10 or later and ChromeOS.
What changes with the Brio 4K
The Brio records up to 4K at 30 fps and 1080p at 60 fps, against the C920s's 30 fps at both of its resolutions. Its recorded field of view is adjustable, with 90, 78 or 65 degrees as three presets, where the C920s records a single 78 degrees diagonal. Its recorded infrared support is yes, which is what makes it usable for Windows Hello style platform authentication. Its recorded built-in microphone is dual omni-directional with a range up to 1.2 m, against the C920s's stereo microphone with a range up to 1 m.
Its recorded HDR is RightLight 3 with HDR. The recorded dimensions are 102 by 27 by 26.5 mm and the recorded weight is 65 g, against the C920s at 162 g.
The one thing the Brio record does not settle for a buyer who cares about privacy is the shutter. No privacy shutter is recorded for the Brio 4K, while the C920s records one as a physical shutter on the lens. That absence in the record is not proof that the camera lacks one, and it has to be put to the manufacturer.
What changes with the Elgato Facecam
The Facecam records 1080p at 60 fps, where the C920s records 30 fps. It records a fixed focus prime lens against the C920s's autofocus with a glass lens, and a field of view adjustable in software against the C920s's fixed 78 degrees diagonal, at 82 degrees. Its recorded built-in microphone is no, so the C920s has the built-in microphone where the Facecam does not. Its recorded mounting is a monitor mount and a tripod thread, its recorded USB connection is USB 3.0 or better over Type-C against the C920s's attached USB-A cable, and its recorded dimensions are 58 by 80 by 48 mm without the mount at a recorded weight of 103 g.
Its recorded product status is that it is discontinued by the manufacturer, and the manufacturer states that the camera has been discontinued. It stays on this site as a reference for what a fixed focus, manually controlled 1080p camera looks like on paper, and it is not a current recommendation.
What decides between them
Whether you need 4K capture, 60 fps at 1080p or infrared support for platform sign-in, which points to the Brio 4K, and whether you want a camera that records a physical shutter over the lens, which points to the C920s. The Facecam records manual exposure control that neither of the other two records, but its manufacturer has discontinued it, so it settles a question rather than a purchase.
What the record does not settle
No price is recorded for any of the three cameras, and no image quality, autofocus behaviour or microphone performance has been measured here. The catalogue holds no privacy shutter specification for the Brio 4K or the Facecam, no software requirement for any of them and no statement about how the C920s shutter is operated.
