What USB webcam works best with Mac mini M2 FaceTime?

AFAIK, FaceTime uses Apple’s video processing pipeline that’s optimized for built-in or Continuity Camera inputs. Some USB webcams — even good ones — don’t integrate tightly enough with that pipeline. When using these cams, especially 1080p or 4K models, FaceTime may either overcompress or under-adapt to variable network conditions, which results in the "connection not good" message on the recipient’s side, even if your local preview looks perfect.

To avoid this, you'll want a webcam that is both UVC-compliant (no drivers needed) and natively tuned to Apple’s AVFoundation framework.

Some that I would suggest are:

• Logitech Brio 500
• Insta360 Link
• Elgato Facecam

If getting a replacement webcam is not in your plans or budget, here are a few things you can try with your existing webcam:

• Try reducing your webcam resolution using a third-party tool like Webcam Settings to 720p before a FaceTime call.
• Avoid usingUSB hubs. Plug the webcam directly into a Thunderbolt port if you can. USB hubs, especially unpowered ones, sometimes introduce enough latency or instability to cause FaceTime hiccups.
• Check your upstream bandwidth: FaceTime is sensitive to upload bandwidth drops. If you're on Wi-Fi, try using Ethernet for more consistent throughput.

Some additional thoughts:

• FaceTime adapts constantly — if your upload dips below threshold even briefly, the other person may see blurry video or dropouts.
• Packet loss and latency matter more than raw bandwidth — a 100 Mbps line with 10% jitter or 2% packet loss will affect FaceTime quality. Higher latency is more common with Satellite Internet connections.
• Wi-Fi congestion can heavily impact FaceTime performance, especially on 2.4 GHz or with crowded mesh setups.
