The author says not to use a wireless headset. And what’s the difference in time to join a meeting between a high quality mirrorless or DSLR camera and a cheap webcam after the initial setup?
I'm guessing it's a reference to the discussion on this[0] article that essentially says that the more advanced/pro level audio and video equipment in the loop, the more likely you are to have a problems and delay the start of the meeting for everyone. Also many DSLR cameras have a 30 minute time limit due to the CMOS sensor overheating.
It's not because the CMOS sensor overheats. That's just some faff someone made up to cover up the real reason.
Imports tariffs for digital video cameras are significantly higher than tariffs for still cameras. So companies like Canon, Nikon, and Sony artificially limit the maximum record time on their DSLRs to get around the higher taxes.
The difference is the DSLR isn't designed to function like a webcam - always plugged in ready to go. "Set and forget" doesn't apply as reliably.
For personal use it's fine. But for work meetings where someone calls you unexpectedly is where things can go wrong if you have unconventional equipment dependencies.
The author recommends an "old DSLR". But you will need utility software running, it's not just a simple driver. Manufacturers make and update these utilities at their discretion. It's a gamble whether it all runs smoothly.
The DSLR needs to be in a special mode, and won't wake up in that mode automatically for incoming calls if powered down, etc.
One hackish idea that I had for quick deployment of my mirrorless as webcam, but that I never implemented was to use a dummy battery ⃰ and have a micro controller act as the dummy battery switch. The switch is then controlled by a process that monitors whether the UVC device that's associated with the mirrorless camera is currently being used.
[*] A power adapter that feeds into a battery shaped terminals, thus allowing an "infinite" battery which.
It could be better than USB charging while using the battery because USB charging might not keep up with the battery drain. The downside of course might be malfunctioning dummy battery causing your camera to fry.
