Internal cameras are generally avoided in bathrooms or bedrooms to protect the dignity of residents and visitors.
In the US, a handful of cities (like Santa Cruz, CA) have attempted to regulate police use of facial recognition, but few have tackled civilian camera privacy. The result is a Wild West: mostly legal until a judge says it isn’t.
The primary privacy concern with modern security cameras is the vulnerability of the cloud. When you view your camera feed on your phone, that data is traveling through the internet.
The backlash against unregulated home surveillance is growing. We are already seeing legislative trends:
If your video feed isn't encrypted (End-to-End Encryption or E2EE), a hacker on your Wi-Fi can "sniff" the data.
You are trusting a third party to secure your data.
Most privacy breaches aren't caused by high-tech "hacking," but by poor digital hygiene.
