[Cryptography] doorbells for Ukraine

[William Allen Simpson]

Surely somebody else has already thought of this, but....

Ring had/has a Ukraine R&D facility.

Ukraine needs to detect incoming shells, missiles, drones.

Wouldn't a few (thousand) cloud connected cameras and microphones be
able to determine paths and trajectories?

Also, is there any ongoing public effort to standardize secure
Nest and Ring interoperable communications?
