Re: Tape
A shutter that covers the camera and possibly disconnects the microphone with a switch.The weird thing is, this is how laptops used to work.
In 2004, or maybe 2003, I bought a Dell laptop. On the chassis it had three physical slider switches to enable/disable:
1) WiFi (yay 802.11a/b/g)
2) Bluetooth
3) Mic/Camera
If you enable the switch, then software can enable/disable that service, but only if the switch was set to 'on' for that function. If set to 'off' then the software setting was irrelevant, it was off.
I'm not sure why these hardware switches were removed - actually, I lie, I do know, cost, money, profit. But they never should have removed them.
