Most laptops have average webcams. Desktops may also not have cams. With more digital meetings, there is a need for better cams. But those are not available due to the current situation. You can, however, use the exceptional cameras on your mobile phone as wifi webcams.
Broadly you would need to do the following-
Download an app on your phone
Install drivers on your laptop
Choose the camera in your meeting app. You are good to go.
There must be more apps too, but these are the ones I experimented with
NDIHxCamera, an iOS app, utilises the NDI standard. This standard, popularised by Newtek, a broadcast solutions company. This app is reasonably simple to use but has been made keeping the broadcast solutions community in mind. To download their app and read more about the tools, please visit this link .
EpocCam is available both for iOS and Android. I experimented with this app on the Microsoft Teams. Kinoni claims that it works with Skype, Zoom and other applications too. It’s simple to use, but please follow the steps mentioned in the setup guide.
