Check forums.logitech.com/t5/Webcams/Can-I-turn-off-red-LED/m-p/… And note that I'm not yet talking about former Adobe Flash security issues that enabled camera use without indicating activation (read: while leaving the activity-indicating light off). If the camera's power circuit includes an LED then how could one power the camera without powering the LED?
I know there is a link in the above comment, but that is for a peripheral device, not an integral laptop camera.
That is a great solution to the privacy issue (excepting sound recording as you said).
It really depends on the type of camera, and how it is built.
Based on your comments, I will assume that the following information is true: 0x00000000 (0) = LED Off 0x00000008 (8) = LED On Please note that only It is taken from: Hence, I do not see why it shouldnt be possible for built-in webcams, since they also require drivers (mine is for example up side down after a fresh install) It seems as if the design of my ASUS notebook is good in this respect.
It uses a hardware video shutter, that cannot be turned on electronically.
I use a very small round rubber that often comes on the bottom of small devices like Vonage Vo IP router.
It provides a little lift off the surface to allow better ventilation and to reduce sliding of the device.
You might also want to look at those laptop webcam cover stickers from EFF.
I used a neat little trick that will go unnoticed by the unsuspecting.
But just to be safe, I'm one of those guys with a dark tape over the camera.
One other thing that I haven't seen mentioned was popularized during the Lower Merion District School spying scandal last year is that the software that was used (LANRev Theft Track) got around the Apple Macbook's camera light protections (camera light is hardwired to camera power) by simply turning it on briefly for a snapshot.
I just use it to cover the LED and persons will think it came with the laptop.
