Sniffing Bluetooth from phones for theft detection

We are developing a platform that allows stores to tag thieves from cctv footage and alert employees if the thief returns. We are investigating collecting the Bluetooth identifier at the same time so that we have 2 identifiers to use, however apparently MAC randomisation on iOS and Android would mean we cant detect the same mac everytime from the same device.

Any ideas on how to overcome? Looking at nfc which won’t work without a paired app, wifi which won’t work unless the thief connects to the “free wifi” etc.
