How are techs dealing with smart glasses and the proliferation of cameras in sensitive areas?

I work in an area where HIPAA (Health Insurance Portability and Accountability Act) standards are required, and cameras are not allowed. I have been wondering how we can ensure people don't wear their smart glasses, whether intentional or accidental.

Most of what I've found online looks like it came from a spy-toy set, or from a travel-spy-toy set, and all seem to be looking for Radio Frequency (RF) and Bluetooth (BT) signals. I am not checking into a hotel or sweeping a shady bathroom. I am able to place a camera to spot the camera's IR, but I don't really care about BT or RF signals because I'm not looking for static hidden cameras.

Pre-answer:

Yes, a BT scanner would work, sort of; it doesn't work if the user changes the name of their smart glasses because those apps just look for BT devices with specific manufacturer names.
