911SentinelCall

How it works.

Cameras, a patrol vehicle and drones watch your property. AI spots people, a person on our team decides what happens, and you get a record of everything.

How does response work?

An automated alert reaches our team within 30 seconds. Within 3 minutes a human operator warns the person through the camera, then calls your team, and the police if your team doesn't respond. No one is ever confronted, and the incident closes with a timestamped record.

  1. A security camera with spotlights mounted on a building wall at night.

    Step 1 of 4

    We watch your property

    Cameras on your property, our camera-equipped patrol vehicle, or drones on big sites. AI watches during the hours you choose, up to 24 a day, and spots people and vehicles where they shouldn't be.

  2. A row of monitors on a desk in a dim operations room.

    Step 2 of 4

    A person checks every alert

    The alert reaches our team within 30 seconds. Within 3 minutes a person checks it against your site rules (working hours, crews, deliveries), so a worker is never treated like a break-in.

  3. A light pole carrying security cameras over an empty parking lot at night.

    Step 3 of 4

    We warn them off

    On camera sites, the person on our team plays a recorded voice warning with the siren and spotlights. Nobody from our team approaches or confronts anyone.

  4. A tablet showing an incident report on a desk at night.

    Step 4 of 4

    We call it in, and you get the record

    If they stay, we call your team, then the police if no one answers in the time you set, or 911 right away in an emergency. Every alert, warning and call is written up with the video, and video is kept 90 days.

Calls the police can act on

Since October 1, 2024, Seattle police have answered alarm-company calls only with proof such as video. Every call we make comes with it: a person who has watched the live video and can tell them exactly what’s happening, and where.
