When it comes to peripherals (earbuds, dashcams, car audio, etc), it's a totally different story. For user convenience these devices happily broadcast useful names, manufacturer data, etc.
But in common sense terms, the privacy implications will be no different than virtually every outdoor security camera you pass by fifty times a day.
It can tell you things like:
- The car that parked nearby last night coincided with "Chad's Galaxy Buds" with MAC address aa:bb:cc:dd:ee:ff. The buds also drove by briefly the previous night.
- Alert on sudden cross-specturm interference (e.g. burglars using a cheap jammer to knock out WiFi cameras).
- Alert on known device contact loss (powered off / left premises).
- Review device movement across a campus/neighborhood (using multiple RF pods).
I have a working PoC. It can run on a low-power computer (e.g. RPi) supporting multiple RF sensors (BT/BLE/WiFi). Has a web UI. Can publish events to an external security system. Currently working on an LLM interface to make it easy for a non-technical operator to set policies and ask questions.
Could be sold as an appliance system or a license for a DIY build.
