The alternative, the led, is not that good. Even if it's 100% hardware controlled, just a brief flash is enough to take a picture of you.

- duskwuff 6y agoIIRC, it takes about half a second for the camera to initialize from power-off and take a photo. The flash this creates is pretty noticeable. Besides, on current versions of macOS, you need to grant permissions to an app before it can use the camera.
- axoltl 6y agoYou should try this on a recent (last 4-5 years or so) Macbook! There is a hardware timer that forces the LED on for at least 3 seconds even if the camera only grabs a single frame.
- bzb3 6y agoI meant that by the time you notice the led, if you do, the picture was already taken and probably sent over the wire.
