Flock CEO Says ‘Just Gunshots’ as Website Lists Other Sounds

Flock Safety CEO Garrett Langley told an audience at TechCrunch Disrupt that the company’s microphones listen for “just gunshots.” Flock’s own product page, however, says its system can also detect fireworks, sideshows and other disruptive events, and a company spokesperson told TechCrunch it can identify potential car crashes. The dispute is not simply over whether the system records conversations: it is also about how broadly Flock describes the sounds its sensors analyze.
Langley’s answer meets Flock’s product page
Asked about the difference between his remarks and Flock’s marketing, Langley replied:
“It’s just gunshots.”
Flock Safety CEO Garrett Langley made the remark during an onstage exchange at TechCrunch Disrupt, according to TechCrunch’s report. The company’s website describes a wider set of audio alerts, including street takeovers and severe crashes, and says its detection library is expanding to cover events relevant to customers.
Flock spokesperson Paris Lewbel told TechCrunch that the technology is “primarily used to detect gunfire” but can also detect fireworks, sideshows and potential car crashes. Lewbel said Langley was emphasizing that the audio system is not designed to monitor conversations or analyze speech, and does not currently detect screaming or distress. That distinction addresses what the system is intended to recognize; it does not erase the company’s description of other sound events it can identify.
Audio analysis is not the same as recording
Flock’s explanation says its sensors analyze sound in rolling windows of about three seconds on the device. The company says audio that does not match a qualifying event is discarded after analysis rather than retained, with an exception for limited, pre-scheduled diagnostic samples used to improve system performance. When a qualifying event is detected, the device saves a short clip and sends an alert. Flock says it does not provide customers with a live audio feed.
That account makes the company’s distinction between analyzing audio and recording it central to the privacy debate. The sensors must process nearby sound to decide whether it matches an event category, even if most of that audio is discarded rather than retained. Flock says the system cannot understand speech, identify voices or search spoken words.
A withdrawn distress-detection pilot still shapes the dispute
The microphone controversy intensified after Flock announced plans to detect sounds of “screaming,” then revised its language to “human distress” following criticism from privacy advocates. Flock later said it removed the feature. In a company post, Chief Product Officer Baily Quintrell wrote that “The feature was only available to a small number of customers as part of a limited trial, and was never broadly released.”
Langley told TechCrunch that Flock had prototyped the feature with a couple of customers after they asked whether microphones installed in parking lots could flag a possible abduction or assault. He acknowledged the company had made mistakes and said it listened to customer concerns. The earlier pilot gives critics a concrete reason to question whether the sensor’s detection categories could change, even as Flock says it has ended that feature.
The open question is how narrowly Flock defines its system
Flock’s product page describes detection beyond gunfire, while the CEO’s short answer suggested a narrower function. The company’s spokesperson clarified the intended distinction: other public-safety sounds can trigger detection, but the system is not meant to monitor speech. Its published explanation also says the detection library may expand as customers identify emerging threats.
At Disrupt, the contrast surfaced amid public scrutiny of Flock’s surveillance products and protests outside the San Francisco venue. For communities weighing the microphones, the concrete issue is what sound categories the system recognizes, what clips it keeps when an event triggers, and who can access those clips. Flock’s own materials list gunshots, fireworks, sideshows and car crashes—not only gunshots.
