The hardware industry has several very good examples of product naming. The Intel Inside campaign and iPhone naming immediately come to mind.

At the other end of the spectrum one of the eager contestants is Logitech’s webcam lineup.  It got off to a promising start in 2012 with the Logitech C920 – the best webcam of it’s time – but across the next 5 years, Logitech’s top webcam lineup bewilderingly grew with 7 puzzling names:

  • 5 business webcams: the C930E, C920-C, C925E, the Pro Webcam and the Brio
  • 2 consumer webcams the C922 Pro Stream and the 4k Pro

To clear up some the confusion I’ve made a comparison table:

A few notes:

It took Logitech more than 4 years after releasing the initial C920 to release a new consumer webcam, the C922 Pro Stream.

Carl Zeiss certifications

The newer C920s seem to have dropped their Carl Zeiss certification as noticed by @mjgraves . I own an old C920 which bears the Carl Zeiss certification on the webcam.

60fps (May 8th update)

Logitech has 3 webcams advertised as being capable of 60fps:

  1. the business oriented C920-C,
  2. the streamer oriented C922 Pro Stream
  3. 4k PRO/Brio.

But the C-925E also supports 60fps. We have a C-925E in the office and, out of the box, we were able to record 720p@60fps in OBS,  XSplit and in Chrome when recording through WebRTC.

Microphone quality 

The sound quality coming from the C920-C and C925E (wide form factor) is superior to that from the C920, C930E and C922 (classic C920 body). The difference can be easily heard in YouTube comparisons. I am not sure it it’s the wider space between the 2 mics, the different grille, different hardware or all 3.

The Logitech 4k Pro/Brio

Logitech has 2 names (and 2 part numbers) for the same webcam. Consumers get the “4k PRO” with a nice looking packaging to attract buyers in stores while businesses get the “Brio” in a simple box. It’s the same webcam.

Logitech 4k pro vs brio packaging

H.264 Advanced Video Coding 

The 4k Pro/Brio is the only high end Logitech webcam that doesn’t include hardware H.264 AVC video encoding. Thus it uses all the 5Gbps bandwidth of USB 3.0 to stream MJPEG video which has to be decoded and reencoded by whatever  video calling/streaming/recording solution you use. It’s sensor can record at max  4096 x 2160 (DCI native) and 3840 x 2160 (UHD).

E stands for H.264 Scalable Video Coding

The C930E, C925E and the Pro Webcam support hardware H.264 SVC encoding (which is different than H.264 AVC). SVC is especially good for live streaming if your end point also supports it. All 3 are business oriented webcams.
