I would argue that if the data is stored, it is only a matter of time before it becomes monetized in the manner you are mentioning. There has to be a firewall to prevent that step being taken. Mindlessly filming for future review in the event of a security issue is one thing. Intelligently analyzing the frames for identification purposes is where the feeling of “my privacy has been invaded, or could easily be in the future via storage of my likeness” comes from.
I don’t see this as a victimless act - just that the victimization is uncertain at present but almost 100% certain to occur the more this behaviour occurs.
