Thanks for the pointers. Frigate, Home Assistant, and HomeKit were mentioned in other comments and we had some discussions there. They're certainly good setups.

Thanks for the pointers. Frigate, Home Assistant, and HomeKit were mentioned in other comments and we had some discussions there. They're certainly good setups. A key design decision for me was using a strong end-to-end encryption scheme between the camera/hub and the app. MLS fit this need perfectly and therefore I came up with the design that is now Privastead. I was also less concerned with supporting many cameras since all I needed was one camera inside my house. Rather, I wanted a lean solution that I could fully understand and reason about. I will however look more carefully into the NVRs you listed to see if I can borrow some ideas to support more cameras more easily in Privastead.
