## Nauti's Take

Cheap hardware paired with an app makes counter surveillance affordable for the first time, which is real progress for travelers, hosts and worker representatives. The open question is field performance: 94 percent in a lab means six missed cameras out of a hundred, and a prototype cannot be bought yet. Anyone checking a room today should pair the method with a scan of the local network.
