If your city or local electrical grid utility is using drones for power line inspections they'll be operated by a FAA part 107 licensed remote pilot, who is familiar with all the legal requirements. No need to be overly concerned about it.
If it's large and expensive the likelihood that it's some random person decreases, it's easy for a UAS with a thermal camera to be $8,000+.
We have identification requirements for other types of planes that cost significantly more.
On the other hand, I've seen utility-branded work clothing at Goodwill.
Or it's a fake thermal camera for $8 -- just some plastics but nothing inside. How is anyone a bit away going to know?
Threat modeling wise, these things could be bad & dangerous in one, two, three, four, more, different ways
