But you missed the part where not you (or your HOA) implements it:
> Services model. Part of the purchase includes a technician showing up and doing the installation. There would be no DIY component.
> Subscription only. The product would be a hardware/software/services bundle with an up front fee and ongoing subscription as default.
So, you have scale. Someone owns all the data. Or three companies, same difference. The state of the "art" security in this sector is beyond laughable (Xiamoi camera showing feed from other peoples camera [0]) and even if not, just buy the dataset. And then the real shit begins.
Give me that dataset of say 20% of the Americans and a decent laptop and I blow Cambridge and their silly facebook data out of the water.
Recognizing people gets ridiculously easy - instead of 7 billion people I only have to identify you out of maybe 100 persons frequenting an area. Cue all the low hanging fruits like your affairs, about all disabilities affecting gait, your bedtime regularity. Let me assume the role of a big store chain: I can not only see plants and garden equipment you buy, but also how you use it and how often you break stuff or let your grass grow brown. Nice!
All these habits, unfiltered, unlike in the internets! How regular is your daily routine? Are you up to some risks due to little sunlight and sport? Your insurer would like to know! Your other insurer would also like to know, should you be considered a traffic risk considering how angry you take your driveway sometimes? But your other insurer has already pattern matched: Is probably an anger management issue. Your future job interviewer thanks you for this red flag!
But hey, you did avoid getting your electric pepper mill stolen that one time, probably!
