It seems like everybody has video doorbells these days. They are one of the most popular components in a modern smart home, but they come with an uncomfortable tradeoff. Every motion event, visitor, and package delivery can end up passing through a company's cloud servers before reaching the homeowner. What could possibly go wrong?
