A 1/2.8-inch Sony sensor and phase-detection autofocus in a camera that costs less than most of this list is the entire case for the Acer A640. Phase detection is the focusing method phone cameras use, and it behaves that way here: the image snaps onto a face instead of drifting through a soft patch the way contrast-detect webcams do. The 77.4-degree lens frames one person at a desk with a little room to spare, and the clip's adjustable jaw grips panels of different thicknesses without wobbling.
We ran it through ordinary work — Teams and Zoom calls, a couple of livestreams, one long webinar — and what we appreciated most is how little it asked of us. No driver, no companion app to learn; it shows up in the meeting software's camera list and delivers 4K. The detail we keep coming back to is the cabling: Acer includes a USB-A cable and a USB-C adapter, so a laptop with only USB-C ports works without a dongle.
The ceiling here is breadth, not image. If you need a camera that follows you across a room, or you want to grade the picture yourself with ISO and shutter controls, the premium picks below do things this one doesn't. For a camera that sits on a monitor and makes you look sharp, we haven't seen the extra money buy a visibly better picture at call resolution.
Pros
- Sony 1/2.8-inch sensor at a budget price
- PDAF autofocus locks on fast
- USB-A cable and USB-C adapter included
- Sliding privacy shutter
Cons
- Uneven support outside mainstream apps
Our default 4K pick: a Sony sensor, quick PDAF autofocus, and both USB cables in the box for less than most of this list. We think it is the safest buy for calls, classes, and casual streaming.
