For me it’s the paranoia surrounding webcams. People outright refuse to own one and I understand, until they go on and on about how they’re being spied. Here’s the secret - unplug the damn thing when you think you won’t use it or haven’t used it in a while.
They, whoever it is, can’t really spy on you on something that’s already off and unplugged!
Always get the version of the gadget with replaceable batteries unless you want a brick in 3-10 years. Additionally, prefer 18650, AA, AAA batteries, and keep some rechargeable ones around.
Eneloop batteries (the white ones, not the black ones) are the best AA and AAA batteries out there for sure. Panasonic sells a package of Eneloops with a charging device that accepts both AA and AAA batteries, it’s very good. Can be charged via USB and can also charge other devices, it’s the kind of device I dreamed about in the 90s.
