I don't even trust my laptop's camera. It's usually covered in black tape.
Same here. As well as the front facing selfie cam on my phone. And phones get stored in another room out of earshot for 90% of the day.
Honestly, anyone who willingly purchases and brings these 'eyes and ears' spy devices into their home deserves to be surveilled. They will watch and listen to everything you do and say without your consent.
The big question is how to hack them so they only talk to your own personal servers. Not cloud shit, a unix box on your home network.
That way you get a really interesting and cheap platform. But step #1 has to be a lobotomy.
