Uh, no.
Skipping back a bit while watching a movie/show is one thing. The 24/7 recording everything a person encounters in life, with the sole reason being they might want to review it again, is a whole different thing. I'm sure there is someone else out there who wants to livestream their entire life to themselves, but it's not going to be many. Maybe if you're like Drew Barrymore's character in the move '50 First Dates', then I could understand the need to do something like that.
You are arguing without understanding it. It's not for livestreaming your whole life. It's not for livestreaming at all. It's for quickly recalling something you might have just missed. It doesn't need all-day capacity, just for a few snippets, enough for a few minutes a day. Not even necessarily for permanent storage. You don't need all day any more than you'd need to record a whole day on your DVR just to rewind those few seconds you just missed. For instance, you've never had a moment where you're watching live TV and suddenly think, "I liked that last commercial," but it's too late to record it because you weren't recording. Or more like the old days when they had those pre-infomercial 30-second commercials where they're selling a product and throw an entire address or phone number at you for ordering in the last five seconds of the spot, like you're supposed to get it all down in that time. If you can pay 100% attention to everything around you, never miss so much as a single thing and can recall every detail of the last minute, bully for you. But most of the human race doesn't have that kind of memory.
Even with a continuous overwrite condition of leaving maybe the last hour's worth of video available for review, the power requirements and potential overheating issue alone make it not very easy to solve. Not even LEO bodycams can do that.
Most people have no problem with actioncams like GoPros overheating. I've had a Panasonic and Chinese action cams run for hours at a time without overheating. Especially since this would not need 4k/60fps video. 720p at 10fps might be sufficient. Less processor overhead means less power consumption, meaning less heat and longer battery life.
Where did I ask for an hour of video? Where are you getting this from? I asked for 30 seconds. You guys just seem to be making things up to come up with objections.
I'm gone. I thought Anandtech was supposed to be a reasonable forum, but it seems people just want to be argumentative.
