IMHO the market is too small and is very price-conscious, so they'll just do it themselves if you try any margin. And you'll need the margin because the consumer who wants this is willing to put up with some error rate on things they build but not on things they buy. So they might say "Oh yeah, when the full power goes out, I have to reset it, but that almost never happens" or "Yeah, I have to type in my Google API key every two weeks but that's okay since it's only $k". Essentially, the same people who care about this are also likely to say "you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem" to Dropbox. If you do succeed building and selling this I'll be very impressed. Lots of people are trying the local storage thing, though: (not customizable store-to-my-S3 stuff, but I think that's a vanishingly small market) * https://www.indiegogo.com/projects/vacos-cam-smartest-ai-wire-free-security-camera#/ https://www.indiegogo.com/projects/vacos-cam-smartest-ai-wir... * https://www.indiegogo.com/projects/wuuk-the-world-s-most-advanced-smart-doorbell#/ https://www.indiegogo.com/projects/wuuk-the-world-s-most-adv... * https://www.indiegogo.com/projects/imilab-ec2-your-life-free-24-x-7-security-guard#/ https://www.indiegogo.com/projects/imilab-ec2-your-life-free... * https://www.indiegogo.com/projects/camect-world-s-smartest-most-private-camera-hub#/ https://www.indiegogo.com/projects/camect-world-s-smartest-m... * https://www.indiegogo.com/projects/capsulecam-home-security-camera-made-smarter--2#/ https://www.indiegogo.com/projects/capsulecam-home-security-... * https://www.indiegogo.com/projects/simcam-an-unparalleled-ai-home-security-camera#/ https://www.indiegogo.com/projects/simcam-an-unparalleled-ai...
