Your video doorbell functions as a silent, persistent biometric scanner for every delivery driver, neighbor, and stranger who walks within its field of view. While you may see a security tool, the device is simultaneously capturing facial geometry and converting it into a permanent, unresettable biometric template. This is the reality of the modern smart home surveillance economy, where the convenience of a \”familiar face\” notification comes at the cost of everyone else’s privacy.
The industry is currently hitting a wall as this \”consent gap\” — the space between a homeowner’s opt-in and a bystander’s total lack of choice — becomes a legal liability. Between June and July 2026, three major class-action lawsuits were filed against the industry’s biggest players. In Sigwalt v. Amazon, filed in the Western District of Washington, plaintiffs are seeking over $5 million in damages for Ring’s data practices. Meanwhile, Google is facing two separate class actions in the Northern District of California: Fennessy v. Google and Trevino v. Google, both targeting Nest’s biometric collection methods.
Ring’s \”Familiar Faces\” feature, launched in September 2025, uses AI to create biometric templates stored in the cloud. Nest’s \”Familiar Face Detection\” is even more aggressive, enabled by default for millions of users. It captures facial geometry from anyone who walks into the camera’s field of view. Unlike a password, which you can change if it is compromised, your face is a permanent identifier. Once that mathematical template is generated, it cannot be reset.
The homeowner’s consent does not extend to the people being recorded, creating a fundamental disconnect in how these systems operate. As Adam Schwartz, Privacy Litigation Director at the Electronic Frontier Foundation, put it: “It’s troubling that companies are making a product that by design is taking biometric information from people who are doing the innocent act of walking onto a porch.” Calli Schroeder, Senior Counsel at the Electronic Privacy Information Center, echoed this sentiment: “Invasive for anyone who walks within range of your Ring doorbell.”
The companies clearly know this is a legal minefield. Both Ring and Nest have disabled these biometric features in jurisdictions with strict privacy laws, such as Illinois, Texas, and Portland, Oregon. This is not a technical limitation; it is a calculated business decision. They know exactly where the legal risk is too high to operate, yet they continue to deploy these features everywhere else, effectively treating the rest of the country as a testing ground for biometric surveillance.
The financial stakes are massive. Google has already paid $1.375 billion to settle a Texas lawsuit over biometric data collection, and Meta previously paid $1.4 billion for similar facial recognition practices. With 58.9 million U.S. households now using video doorbells — Ring holding 43 percent market share, Nest at 7 percent — the potential for liability is staggering. This is particularly relevant when you look at the broader ecosystem. As our coverage of Nest Sight Search showed, Google is effectively double-dipping: charging users a $20 monthly subscription for advanced perception features while simultaneously harvesting biometric data from every passerby on the same hardware.
This creates a strange, uncomfortable tension for the consumer. While 48 percent of U.S. households have adopted these devices, there is a growing trust deficit. A June 2026 survey from Reviews.org found that 65 percent of consumers are concerned about AI assistants. People want the security of a smart home, but they are increasingly wary of the surveillance infrastructure required to power it.
The “consent gap” is not a bug; it is a structural design feature of the smart home surveillance economy. For years, the industry has banked on the idea that the homeowner’s subscription fee justifies the data collection. But as the costs of biometric litigation begin to outweigh the revenue from these AI-powered subscriptions, the model is starting to look unsustainable. With Google and Meta already paying billions in settlements, the industry faces a future where the legal liability for biometric harvesting may soon exceed the profit margins of their subscription-based surveillance models.
