Look Up! Your Streetlamp Is Watching You | Joshua Emerson Smith - a podcast by San Diego Union-Tribune

San Diego has installed thousands of microphones and cameras in so-called smart streetlamps in recent years as part of a program to assess traffic and parking patterns throughout the city.

However, the technology over the last year caught the attention of law enforcement. When police officers picked up Hernandez last summer, they had never used a streetlamp camera in an investigation.

Today, such video has been viewed in connection with more than 140 police investigations. Officers have increasingly turned to the footage to help crack cases, as frequently as 20 times a month.

Police department officials have said that the video footage has been crucial in roughly 40 percent of these cases.
