Flock CEO says microphones detect “just gunshots,” while website lists more sounds

Flock CEO Garrett Langley said the company’s microphones detect “just gunshots,” but Flock’s website describes audio systems that can detect other sounds, including fireworks, sideshows and potential car crashes.

At TechCrunch Disrupt, Langley defended Gunshot Detection, a product that listens for gunshots and other ambient audio in nearby neighborhoods. He said the company had prototyped distress detection with a couple of customers after they asked for alerts about abductions or harm, but removed that capability after people raised concerns. Flock later said it does not currently detect human screaming or distress and is not designed to monitor conversations or analyze speech.

Flock spokesperson Paris Lewbel told TechCrunch the technology is primarily used to detect gunfire, but can also detect fireworks, sideshows and potential car crashes. The company’s website says its detection library is continually expanding to include emerging threats relevant to customers’ needs.

Langley said Flock’s microphone count is comparable to ShotSpotter, which had about 25,000 microphones as of 2024, according to Wired. His remarks come amid scrutiny from privacy advocates, including the ACLU, and public concern about surveillance. Protesters gathered outside the San Francisco venue during his appearance. Texas and Florida have moved to end their relationships with Flock, and Amazon’s Ring has ended its partnership with the company.
