# Deep Sentinel

> Deep Sentinel is a Pleasanton, California security company that pairs proprietary AI with live human guards to stop crime while it is happening rather than document it after the fact. Its cameras use computer vision to filter out harmless motion and surface genuine threats to remote 'LiveSentinel' guards, who intervene through two-way audio and a 100+ dB siren within seconds and escalate to police with verified, crime-in-progress information. The company sells to both homeowners and businesses and has expanded into a Bring Your Own Camera program that works with major third-party camera brands.
