Use your Android phone camera as a wireless webcam on Windows, Mac & Linux. Works with all your fav desktop video apps Supports resolutions up to 4K. It can sends sound from the phone as well. FREE. The $4.49 upgrade to "Pro" gets you more camera controls.
I saw "Camo" for using a phone as a WebCam, but that only works with iPhones, which I don't use. I was searching for an Android solution and found this one and it works really well. You can attach it via USB for a wired connection as well. Totally acceptable at the FREE level … … then the $4.49 upgrade to "Pro" gets you exposure controls, color controls, white balance, flash on/off, image mirror, zoom bar, and more. Nice app. Made in Finland. 🇫🇮
