Here's an idea for you -- property evaluation. It's not hyper-specific to your monitoring system, but it would be very interesting to understand before buying a house:

1. How loud the neighbhorhood is over time periods, eg sat night vs tues morning 2. air quality, enviromental factors, etc. 3. What percentage of vehicles/people/devices are net-new (over a time period) versus recoccuring, as identified by MAC.

I would personally pay in the low hundreds to understand overall loudness levels for a house I am about to buy, although I am fairly sensitive to sound. My wife would probably pay for the new-new people metrics.

IMO, you could charge a per-device report and deploy a unit for a week, much like a home inspector report. It would give you a revenue stream on the buy or sell side, and let you own your devices as you iterate on the sensor package.

Anyways, just my 2c, gl with your PoC.

What are you hoping this tool will do for the world?

Very cool. Do you happen to have any kind of mailing list, blog, etc?

Could this be used to identify masked ICE agents?

So you collect PII in a public space and use correlations to deanonymize, link and collect further PII. A GDPRinator 9000.
