Yep, here's the applicable section of NC law:
15A-300.1 Restrictions on use of UAS
General Prohibitions. – No person, entity, or State agency shall use an unmanned aircraft system to do any of the following:
Conduct surveillance of:
- A person or a dwelling occupied by a person and that dwelling’s curtilage without the person’s consent.
- A private real property without the consent of the property’s owner, easement holder, or lessee.
Photograph an individual, without the individual’s consent, for the purpose of publishing or otherwise publicly disseminating the photograph. This subdivision shall not apply to newsgathering, newsworthy events, or events or places to which the general public is invited.
It seems to me that the operative words in the statute are
Conduct Surveillance of.
Otherwise, there is no prohibition against flying a drone over or across private property or even using a drone to take pictures of private property in North Carolina provided the drone is operated in accordance with FAA regulations. If fatback68 believes that the drones he's seen over his property in the last three years are unjustly surveilling him, then he should file a complaint or bring a suit against the perpetrator(s) and let the courts decide.
What is surveillance? In the simplest of terms, it's defined as close observation, a rather subjective notion which implies intent. Depending on the merits of the case, fatback68 might anticipate a countersuit.
