Night security that never gets tired.

Patroller is a security robot that patrols your site from dusk to dawn, sees in the dark, spots intruders and alerts your team in seconds, with live video to act on.

The weak hours are between 1am and 4am.

One guard at one post can’t watch the back fence, the yard and the gate at once. When something happens, owners hear about it the next morning, with no footage and no proof of what the patrol actually covered.

Patrols the whole site

Follows set routes around your perimeter, yards and car parks every night, steering around people, vehicles and obstacles.

Sees and decides

Infrared night vision and on-board AI detect people in restricted zones after hours, based on rules you set.

Alerts in seconds

Your guard and manager get a push and SMS alert with a snapshot, then live video and control of the robot.

A night on patrol

Patroller walks the routes we map for your site, all night. When it sees someone where they shouldn’t be, this is what happens.

  1. Detect. A person is seen in a restricted zone after hours, in daylight or infrared.
  2. Deter. Spotlight, siren and a spoken warning: “You are being recorded. Security has been notified.”
  3. Alert. Push and SMS with a snapshot to your guard and manager, then live video and control.
  4. Escalate. No response? Phone calls go up your chain (Premium and Enterprise). Everything is logged.

  2. 360° LiDARMaps your site and sees obstacles all around
  3. Light ring and sirenLights up and warns intruders that they are recorded
  4. Ultrasonic sensorsStops safely for people, cars and new obstacles
  5. On-board AI computerRuns person detection on the robot itself
  6. Four-wheel driveBuilt for compounds, car parks and yards
  7. Battery for a full nightPatrols dusk to dawn, then returns to its dock
  8. Charging contactsDocks and recharges by itself
  9. 4G and Wi-FiAlerts still get through when Wi-Fi drops

We don’t replace your guards. We make them more effective.

Patroller covers the ground. Your guards stay at the gate or control point and respond to verified alerts instead of walking the same loop all night.

Where Patroller is today.

Patroller’s software is built and working in simulation: site mapping, autonomous patrol, person detection, the security rules engine and alerts. We are now building the first physical robot in a 6-month programme, ending with repeated night patrols at a test site in Enugu.

Founding pilot sites get the first robots, help shape Patroller for real Nigerian sites, and pay 15% less for the first 3 months.

We’ll walk your site with your security lead, sketch the patrol routes and restricted zones, and tell you which plan fits. Founding pilot sites in Enugu get 15% off the first 3 months.
