What happens when someone gets in
One night on a site we watch, from the first alert to the morning report.
11:42 pm
Someone climbs your fence
The site is closed and dark. A person comes over the fence near the materials.
11:42 pm
Within 30 seconds, we know
The camera’s AI spots a person and sends the alert to our team.
11:44 pm
Within 3 minutes, we warn them off
An operator checks the video, then plays a recorded voice warning, sounds the siren and turns on the spotlights. Nobody from our team confronts anyone.
11:47 pm
Then we call it in
Your team first. If no one answers in the minutes you agreed, the police — or 911 right away in an emergency.
7:00 am
By morning, you have the record
The video and a written report of what happened, ready when you start your day.
Why property owners choose us
Warned off while it's happening
A person on our team acts within 3 minutes of the alert, while it's happening, not the next morning when the copper is already gone.
A fraction of a guard
One Seattle guard runs about $9,380 a month for 8 hours a night. Our cameras watch the whole site for the same hours from $900, with no per-call fees.
Local, and the founders pick up
A Lynnwood team of security and AI experts with 60+ years of combined experience. Month to month, so we earn it every month.
What does 911 Sentinel do?
911 Sentinel is a Lynnwood-based security company that watches commercial property and construction sites across western Washington through AI cameras, a camera-equipped patrol vehicle, and drones on large sites. When someone shows up who shouldn't, an operator warns them through the camera within 3 minutes, then calls your team and the police. Camera monitoring starts at $900/mo, with a 30-day free trial.
