In public spaces, the legal expectation of privacy is minimal. If you walk down a public sidewalk, you can be photographed or filmed without permission.

The sales pitch is compelling. A $50 camera from an online retailer or a $300 video doorbell promises real-time alerts, cloud storage of footage, two-way audio, and artificial intelligence that can distinguish between a falling leaf and a lurking stranger. For millions, these devices have delivered on that promise. In public spaces, the legal expectation of privacy

Legally, in many jurisdictions, as long as the
