Is the Lenovo ThinkVision M50 good for video calls?

Yes for everyday meetings. It shoots 1080p at 30 fps with autofocus and has a built-in mic, which covers standard calls. In very dim rooms the image gets noisy because there is no built-in light.

Does the M50 support Windows Hello?

No. It has no facial recognition, so you cannot use it to sign in to Windows with your face. You will still need a password, PIN or fingerprint reader.

Does it have a microphone and speaker?

It has a built-in microphone for your voice. It has no speaker, so call audio comes from your laptop or separate speakers.

How does it mount on a monitor?

It uses a clip mount that sits on the top edge of most monitors and laptops. It weighs about 4.4 ounces, light enough to stay put without tipping a thin screen.

What resolution and frame rate does it record?

It captures 1920x1080 Full HD at up to 30 fps. That is fine for meetings and chat but below the 60 fps some streamers prefer.

Does it need extra software?

No. It connects over USB and works with common video apps without special drivers. Lenovo may offer optional software, but the camera works as a plug-and-play device.
