FWIW My web cams have a lens cover, just because it is possible to activate without the LED lighting. Little effort convenience has its privacy price (and pitfalls, when folk forget how to do it manually  ). |
I fitted an inline "Torpedo" switch on my 32" monitor's mains cable as the PSU is otherwise always on. I use a 23" monitor and the 32" one is for visitors to my library, or mirror my screen to visitor, or set-box check Sat signals.
Anything with a touch switch or momentary action press button that is "instantly" active is not turning off. It's annoying as a signal on a port may "wake" it.
I will fit more real on/off switches on infrequently used stuff.
Do unplug the mains cable before cutting.
The lack of real switches is:
1) To save 50c.
2) Illusion of instant on, no boot. IMO the 0.5W standby is rare.
3) Part of hiding all controls. Monitors are now ghastly to adjust and TVs crippled if remote is lost or flat. Though sometimes there is a real power switch on the rear. Not when there is an external PSU.
Ironically a Linear transformer based PSU may take far less (almost nothing) than a SMPSU (brick or wall wart) when the equipment is really off.
