Brightness, dark to bright

How to read it

Resolution: The width and height of the frames that actually arrive, not the number on the box.
Measured frame rate: Frames counted in the last second as the browser presents them. It drops when the camera stretches exposure in dim light.
Sizes accepted: We ask the camera for each standard size in turn. A size it refuses is one your call app cannot get either.
Light: Average brightness of the picture from 0 (black) to 255 (white), with a histogram. Most of the bars piled on the left means the room is too dark.

Is the video recorded or uploaded?

No. The picture goes from your camera to this tab and nowhere else. A snapshot is made in the page and saved only if you press download.

Why is the frame rate below 30?

Many webcams slow down in low light to collect more light per frame. Add light in front of you and watch the measured number climb.

It says the camera is in use. Why?

Another app, often a call app, has the camera open. Close it, then press Start again. On Windows only one app can hold most webcams at a time.

Is the first resolution the camera's maximum?

We ask for the largest picture the browser allows. Press "Check every size" to see each standard size the camera accepts.
