A friend of mine in school had a similar thought - make body cams so cheap that everyone has one. Watch the watchmen.

I’ve considered making this a commercial reality, but we’ve seen that ubiquitous cameras don’t necessarily stop cops or authoritarians from kneeling on your neck, if they don’t feel shame.

Facial recognition databases of public sector employees will be the straw that breaks this camel's back.

I specifically have considered this in terms of protecting workers from (otherwise private or hidden) workplace abuse.

Two thoughts:

1. Amazon blink is an interesting hardware platform. With a power-optimized SoC, they achieve several years of intermittent 1080P video on a single AA battery. A similar approach and price point for body cam / dash cam would free users from having to constantly charge.

2. If you're designing cameras to protect human rights, you'll have to carefully consider the storage backend. Users must not lose access to a local copy of their own video because a central video service will be a choke point for censorship where critical evidence can disappear.

AR / AI glasses will be this.

I don't know. Is it better that it's obvious or not? I was thinking a buttonhole camera linked to your phone with an LED indicator when recording.

I’m embarrassed to admit how readily I overlooked the “on” in “buttonhole”, and even more embarrassed how afraid I became when your post still made sense.

Well, for certain fringe definitions of “sense”.
