Larger sensors like Sony STARVIS gather more light in dim rooms. Every pick names a large or STARVIS sensor, ordered from the lowest price.
This is a research roundup, not a lab test: top resolution, max frame rate and sensor come from each maker's published specs; nothing here was tested in-house, and a missing max frame rate is flagged, not filled in.

Acer A640 4K Webcam on Amazon (opens in a new tab)

Best for
- Keeping the budget tight.
Skip if
- Look at the other picks if you need a feature not covered above.
Why we like it
It was the lowest-priced webcam here at the time of writing. PDAF autofocus locks on quickly without the hunting of contrast autofocus, and a Sony 1/2.8-inch sensor records 4K. It suits streamers who move closer and further from the camera.
Like the EMEET S600 and N680E Pro, it has a PDAF focus and framing, while the Kiyo V2 uses an AI framing. It also comes with AI noise cancelling on the microphone and a USB-A to USB-C adapter in the box. 4K output needs a USB 3 port and an app that accepts 4K; most video-call apps send 1080p or less. It was the cheapest of the group when we checked; the EMEET S600 was the next step up.
Key dimensions & specs
- Top resolution: 4K30, 1080p60
- Max frame rate: 60fps
