Flock installed LPR's without permits and has now been banned from operating in two states

Do mobile devices really transmit their mac address? I thought they were used only at Layer 2. Without doing an research, I would think the mobile devices transmit only their EIN and/or SIM number.
Flock Safety does not currently offer MAC address harvesting, and SignalTrace cannot be natively activated on a standard Flock cameras

SignalTrace is an advanced signal intelligence platform. It bridges visual license plate data with radio frequency (RF) sensors to passively sweep up:
Bluetooth & Wi-Fi MAC Addresses: From smartphones, smartwatches, wireless earbuds, and infotainment systems.
RFID Tags & IoT Devices: From toll transponders, tire pressure monitoring systems (TPMS), smart tags, and even pet microchips.

So, probably not? :idk:
