Intrusion law in North Carolina does not differ in any significant way from the law described in the General Elements of an Intrusion Claim section of this guide. See Miller v. Brooks, 472 S.E.2d 350, 353-55 (N.C. Ct. App. 1996). As result, you should follow the general advice outlined in the section on Practical Tips for Avoiding Liability When Gathering Private Information.
Always attempt to get the consent of any parties you are filming or whose privacy you might otherwise be intruding into. Consent from the subject will likely give you a strong defense against an intrusion claim. See Miller v. Brooks, 472 S.E.2d 350, 354-55 (N.C. Ct. App. 1996).
