HOAs are practically incorporated hamlets - local governments. There is a government (board) which imposes taxed (dues) and imposes zoning & other laws (rules), and can impose debilitating punishments (liens) against subjects (residents). Some are little more than friendly neighbors trying to keep neighborhood home values stable, others are wannabe tyrannical dictatorships. I could certainly see an HOA installing (increasingly cheap!) license plate & face recognition to monitor local activity "for security reasons"; seems innocuous enough if actually used sparingly to help police solve real crimes, but could quickly become obnoxious/oppressive when meddling board members with hyperactive imaginations start "looking for trouble before it starts". Yes, "HOA going 1984" is not full blown 1984, but it can terrorize & harm locals until they manage to move (i.e.: persuade someone else to move into a place locals are fleeing for reasons), and if less problematic still proceeds to normalize progression of 1984-ish governance.
