Meet the action video equivalent of the selfie-stick, an unattended PTZ mechanism which tracks targets by rf tag, for $400, plus attachments.

Should have been named P-T-Me. Multiple tags can be used with one base. Multiple bases and multiple tags make a multi-view movie.
No security applications on their website, and applicability seems limited by the fact that criminals are notoriously resistant to wearing rf tags... Also it works outdoor only (for now).
But maybe auto-tracking a complicit person of interest, like a politician or celeb? Or how about a rf tag placed inside high-priced vehicles at a car lot? Or a tag inside high ticket electronics in a retail environment?
