Yesterday I wrote about Dayton Ohio’s plan for an aerial surveillance system similar to the “nightmare scenario” ARGUS wide-area surveillance technology. Actually, ARGUS is just the most advanced of a number of such “persistent wide-area surveillance” systems in existence and development. They include Constant Hawk, Angel Fire, Kestrel (used on blimps in Afghanistan), and Gorgon Stare.

How domestic drones will affect our privacy depends on how the technology is used and deployed. And that depends on a lot of factors. Technologies never exist in isolation—their impact on society is always the result of interactions between the technology's potential, existing institutions and interests, and the law, architecture, and culture around them. We should put good privacy protections in place no matter what, but as drone technology unfolds, here are some of the factors that could influence the size and scope of their deployment within the United States:

As drone regulation legislation works its way through Congress and the 30 (so far) state legislatures where it has been introduced, one question that we hear a lot these days is, “we’ve had police helicopters for a long time, what’s so different about drones?”

For one thing, police helicopters do raise privacy issues. Because of the expense of using manned police aircraft, privacy invasions have not risen to the level that legislators have felt compelled to address them, but incidents do happen. In 2005, for example, a police helicopter supposedly monitoring a street protest in New York City instead trained its infrared camera for a prolonged period on a couple making love on a pitch-black rooftop patio. Any police helicopter that followed a citizen around town for no reason, or hovered over the backyard of innocent homeowners whose daughter was sunbathing with her friends, would probably draw complaints. With drones, scenarios like those are bound to happen much more frequently. And that’s because there are some critical distinctions between manned and unmanned aircraft.

The PBS series NOVA, “Rise of the Drones,” recently aired a segment detailing the capabilities of a powerful aerial surveillance system known as ARGUS-IS, which is basically a super-high, 1.8 gigapixel resolution camera that can be mounted on a drone. As demonstrated in this clip, the system is capable of high-resolution monitoring and recording of an entire city. (The clip was written about in DefenseTech and in Slate.)

In the clip, the developer explains how the technology (which he also refers to with the apt name “Wide Area Persistent Stare”) is “equivalent to having up to a hundred Predators look at an area the size of a medium-sized city at once.”
