I'd love to see stats on how many people actually still use webcams for online meetings. I rarely do, and I don't care if anyone else turns theirs on. Watching someone act like they aren't hyper-aware of what they look like on camera adds very little value to the conversation. Unless you're in sales, trying to make a good impression, or some kind of introductory meeting, who cares?

True. But I think one can avoid the credibility damage presenting or appearing poorly over time can cause with just a little thought about audio and lighting etc. There are gains to be had simply by being seen and heard better even if there is low ‘diminishing returns’ point.

If you go this route, please make sure your system is robust and ready to go before meetings. We had to ask one employee to go back to his reliable built-in webcam because every other meeting started with 2 minutes of him getting his camera turned on, messing with audio inputs, getting his microphone boom in place, and fighting other quirks. He also had a tendency to drop out of long meetings when his camera overheat…

He was probably using software, like Canon's Webcam Utility, to stream his camera's HDMI OUT to his computer instead of using a capture card. He likely did this because of his camera not having "clean" HDMI output (i.e. you'd see icons if he were to capture what was on his camera's screen). Software like this is extremely unreliable by comparison and consumes CPU cycles like crazy, both on the camera and on your computer.

Additionally, for most cameras, the input feed used by the software goes through the camera's image processing stack as if they were using the real-time "Live View" feature (i.e. showing you the image you're going to take post-processing, i.e. real-time image processing). This often heats the camera up and causes it to shut down due to thermal overload. If you use a capture card, it captures whatever's on the screen without hitting the image processing stack, which is much less resource-intensive.

The first person I interviewed with this setup had the same problem. He looked great, but the software processing the input from his camera made him lag horribly.

I have a Canon M200 mirrorless SLR with an Elgato HDMI Capture card and have used it for all-day online meetings (even through OBS!) with no issues at all. Startup takes me, like, 30 seconds: turn key and fill lights on, turn camera on, press hotkey to start OBS, Krisp and Zoom, turn on video.

Agree 100% - This is why I eventually dropped it. I used to run a photography side gig, so I reused my full frame DSLR, nice portrait lens and lighting + cloth backdrop. But I had cables everywhere and multiple points of failure in the chain. Camera could overheat, software was wonky, something would get unplugged, and there was stress on the CPU at times too due to 3rd party apps required. Overall it just wasn't wor…

What camera did you end up with that had a narrow FOV?

The quality aspect is obviously important but I'd suggest that the location of the lens is also vital if you don't want to have meetings where everyone seems to be not looking at you. I cannot wait until cameras work behind the screen and can be positioned right in the center but for now, the only option I found was something called Center Cam that mounts a small lense on a skinny support that can be positioned over…

That’s a super neat idea! I have a feeling the inevitable solution to this need will be a combo of a tech like Apple’s Center Stage and some sort of eye-focusing alteration to the image, like a live deep fake of yourself (just the eyes). Software-only means widespread adoption.

FaceTime actually did the eye adjustment thing for a bit, but they disabled it. Not sure why, it seemed to work okay. Maybe it freaked people out though.

Agreed. Using an SLR with a capture card and proper three-point lighting makes you look amazing in online meetings. Very easy to set up as well. Will cost about $700 to get going with, but it's a one-time cost that will work on any computer for a long time.

Not every camera has clean HDMI output, though. It's hard to find a single list of cameras that have this feature, so you have to Google around. Cameras without clean HDMI out will show icons and focus windows when you stream from them.

Why can’t laptops just get smartphone cameras? Is the BOM impact of a phone camera from 2018 really that high?

not the bom, it's the screen thickness.

Most laptops screens are much thinner than a smartphone.

That said, i'd gladly have a little camera bump.

Honestly the video adds pretty much nothing to a Zoom meeting. You're better off without it. Maybe it's different for managers/executives but for engineers it's more of a distraction.

People built Linux over email. Having audio meetings is more than enough.
