Definitely cool technology, only not for me. I'll never place a camera in my home that is connected to some cloud service or company database. That data is simply too valuable for me to send out to a "trusted" party.
(For the convenience, I ended up using a Google Home, and I'll likely switch to an Apple HomePod next as they seem the most trustworthy with your data.)
If Piccolo will make money through data (like Amazon or Google), there's virtually no way for it to be non-intrusive unlike with audio, as we'd just be using it for turning off our lights rather than searching for the nearest French restaurant. Data would have to come from visual recognition. Hopefully the lack of connection needed to a cloud in this situation will result in more security? Anyway, curious to see how it works.
