Browser operation verification Web camera test

This is a test tool that allows you to check your webcam video, actual resolution, measured frame rate, and microphone audio input volume using only a browser.
It is ideal for verifying webcam operation and for setting up before online meetings (Zoom / Teams / Google Meet, etc.).
It also supports downloading and saving snapshots (still images) of what you capture.
All processing is completed on your device, and no video or audio is sent to external servers.
