Perhaps tangential, but is there any way to be certain whether the webcam light can be controlled by software? I often wonder if my MBP camera is necessarily off just because the ominous little green light isn't shining.

That would be hardware-specific, but probably _always_ independently controllable. It's not like the IC manufacturer is going to link the CCD to an LED.

Am I the only one who doesn't have a microphone or webcam in my laptop these days (6 year old Lenovo T61)? It didn't come with a webcam and I unplugged the mic. I can't stand the thought of them pointing at me.

My laptop has a sliding piece of plastic that covers the webcam http://i.imgur.com/zRnNOEQ.jpg

Why not? It's easy. Turn the LED on when there's current on the CCD's power input.

Earlier quoted context omitted.

I don't think so. It seems like software controls whether that little green light is on. Unless the green light is on whenever the webcam is powered.

Hardware-based can mean two things.

    1. The CCD IC controls the LED
    2. A intermediate IC has firmware that controls the CCD and LED
It is safe to assume that the LED is always controlled either by an OS driver, or by an intermediate firmware. I doubt it would ever be controlled by the 'final' camera IC.

This means that, for Macbooks, running the CCD without the LED is _very difficult_, but, if the camera supports firmware upgrades, it is possible. And there could be undocumented commands to enable video without the LED.

If you're afraid of script-kiddies watching you read Reddit, you can probably trust the LED. If you're afraid the NSA has identified you as a special target, you probably cannot.

I would be more useful if someone made a sticker of some sort that allows you to cover the camera when you don't need it, and pull off easily when you do. Maybe a little magnet would do the trick.
