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.

You 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.

With regard to privacy, the microphone is 100x more sensitive than the camera most of the time, and it’s much harder to secure.

This is just for external headsets.

I was very skeptical of the camera covers, but then through conversations with some of my co-workers, I realized that they weren't being used because people were worried about spies secretly turning on the camera. It was 90% of the time just peace of mind that their camera was actually off, instead of having to find the sometimes hard to see options in video chat programs etc.

I have the same with my headset. It has a physical mute button for the microphone, which I engage as soon as I'm done talking in Teams or similar. It's a dumb switch, so instant and with no annoying woman telling me I muted. Being a dumb switch it's also tactile, so I can tell by feel if I'm muted or not.

That way I don't have to worry about my annoying my colleagues by my mechanical keyboard, occasional excess gas events or similar.

> The camera is engineered so that it can’t activate without the camera indicator light also turning on. Has anyone torn down the hardware and verified this lately? It should not be a complicated feature at all. Just ensure you have the same voltage applied to your LED circuit as your camera circuit, and enforce that by having them on the same wire...

Also, pretty unlikely, but what if the LED dies? :)

Just as a social observation I noticed a pattern which always struck me pretty hard:

Nearly all (say 9 out of 10, and not, it's not an exaggeration) of my friends – me included FWIW – have some kind of cover over their webcams. This is true even for people who you would describe as the opposite of tech-savvy. Sometimes these folks even have no ad blocker installed and use Chrome happily.

But still: Everybody has something over their webcams. It is truly ubiquitous! Might it be we dislike the fact something like an eye stares us right into the face all the time?

There's a reason Zukerberg's laptop has its mic and camera tapped up. It doesn't matter what device you use unless there's a physical switch to disconnect it'll never be safe. Software can ALWAYS have zero days, just because it hasn't been exploited yet doesn't mean it can't be.

But can't you specifically wire the indicator light to always be lit if the camera has power?

I don't see Apple claiming they've done that but a correct design would make the indicator light work that way and be related to software at all. Meaning you could only disable the indicator light by physically modifying the device.

Even though you could get far more information by hacking the built in microphone.....

I would say you are equally likely to catch someone jacking off through the webcam as to catch valuable information through the microphone. They are therefore equally lucrative

Haha some people would pay to have a plausibly deniable third party send masturbation videos to their contacts

If you close your Mac notebook with a camera cover installed, you might damage your display because the clearance between the display and keyboard is designed to very tight tolerances. Doesn't this sound like an engineering oversight and not a user error? Why are camera covers not just part of the design? My phone camera physically retracts when not in use.

I am convinced they were ordered at some point to include cameras. They definitely drive up the cost of laptops, especially earlier on when webcams were more expensive. There were so few practical uses in the early days and so few people actually use them today that I am surprised few laptop manufacturers don't allow for security.

I think cameras are generally expected in non-budget laptops just as they are in phones.
