The trade body for America’s security industry has stepped into the fight over networked license plate cameras, publishing policy principles that call for encryption, retention limits and audits even as cities and states move to drop the technology.
The Security Industry Association released the guidance this week, urging federal and state lawmakers to set strict limits on how long non-evidentiary scans are kept, require hardware-level encryption on cameras, and build auditable access controls into deployments. Investigative searches, it argues, should rest on reasonable suspicion and a documented public safety purpose.
The group drew a firm line against proposals to require warrants before officers query a plate database. SIA chief executive Don Erickson said plate readers are “not – and must never become – a tool for mass surveillance or tracking law-abiding citizens,” while warning that warrant mandates would leave the systems unworkable for routine investigations and emergencies.
Critics say that framing misses the point. IPVM and civil liberties groups argue a single camera capture is harmless, but millions of pooled observations become a searchable location history that can reconstruct a driver’s movements over months.
The principles land amid an accelerating backlash. Communities from Massachusetts to Wisconsin have paused contracts, courts have ordered departments to open their files, and bipartisan bills in Washington would cut funding for plate reader fleets.
SIA’s answer is governance rather than retreat: keep the cameras, tighten the rules, and punish misuse. The association also wants vendors held to account, with meaningful enforcement mechanisms written into any new law.
