These activities would certainly be legally incorporated and easy to cross reference.
I also suspect that these ovens don't run 24/7. If they use their drones on a Sunday outside of work hours they can probably weed out (ha) many false positives.

Facilities are leased and sometimes sub-leased all the time. Just because Joe's T-shirt Printing owns three warehouses doesn't mean they haven't rented one out to a yoga studio and another out to a machine shop.
Just because P&Q Precision Tool exists as a business in state records doesn't mean you have any idea that they're operating out of the Joe's T-Shirt Printing Warehouse that was vacant for the last 3yr.
