More communities are putting together networks of cameras that show what is happening in public spaces. Some of this comes at the municipal level, often in the name of preventing or solving crimes, and is increasing happening at the private level as homeowners add cameras to monitor around their home.

If people are concerned about the rise of cameras and analysis (particularly through algorithms and predictive software), will this change their behavior? The United States already has a tendency in recent decades toward private spaces. Scholars and commentators lament the decline of public spaces, the shift toward privatized settings between work and home (think Starbucks or shopping malls), and the primacy of single-family homes. Imagine a society where people are fearful of cameras and decide to curtail their public activity. A variety of technologies could help them limit the time they spend outside their residences: think working from home, grocery and food delivery, and the delivery of all sorts of goods and services to an address.

If this comes to pass, the public realm might be even more impoverished. Will the often think social life and outside activity of suburban neighborhoods continue to dry up? Where will people of different backgrounds and interests interact? What will happen to the thrill of being around crowds and dynamic activity? Would this simply lead to more suspicion and calls for even more cameras and surveillance to figure out who would be so bold to go out (or to turn the surveillance into more private spaces)?

This all may sound pretty dystopian. When I walk down the street in my neighborhood or my community (regular activities for me), I rarely think about the cameras that might be watching. I try to be observant and I do not notice too many surveillance devices. My neighbors may indeed be watching (or able to watch) but it does not feel like a threat. But, sometime soon, just the threat of being watched, let alone different actors using the video and data, may influence the feeling of community.

(Of course, it may not be the cameras that truly could limit public life. Perhaps the true threat comes from the smartphones we all carry and that track us.)
