The webcam decision at entry tier is between two specific Logitech models: the C270 and the C920. Both produce stream-acceptable video. The price difference reflects feature differences that matter mainly to streamers planning long-form careers from day 1.

The C270 is the lower-cost option. It produces 720p video at a price point that fits the tightest entry budgets. For streamers in their first 90 days who want to validate that streaming is something they want to commit to, the C270 is correct.

The C920 is the moderate-upgrade option. It produces 1080p video, includes a wider field of view, and has better low-light performance than the C270. For streamers who already know they are committing to streaming and want a webcam that lasts through the first year before upgrading, the C920 is correct.

The discipline: do not chase higher-tier webcams (Brio, Facecam Pro) at the entry tier. The visual quality difference is invisible to most viewers in the first months of streaming. The dollars are better spent on audio and lighting.
