Sorveo · Perimeter

Know the moment someone crosses the line.

Draw restricted areas and boundary lines on the cameras you already have. When someone enters a no-go zone, crosses your perimeter line or appears on a camera after hours, your team gets an alert with a snapshot — in real time.

Feature overview

What perimeter detection includes.

Restricted-area detection

Mark no-go zones on a camera view. Anyone entering the zone is flagged live, with a snapshot and the camera location.

Line-crossing detection

Draw a boundary along a fence line, gate or roof edge. Someone crossing your perimeter line raises an instant alert.

Presence and activity detection

On monitoring cameras, know when something is happening here, now — ideal for spaces that should be empty.

After-hours unknown-person detection

On secure or after-hours cameras, strangers and unknown faces are flagged while your known staff are recognised.

Vehicle-activity detection

Vehicles idling, passing or entering a zone at gates, yards and forecourts. Vehicle presence only — see vehicle activity detection.

Per-camera AI profiles

Set each camera to face, presence, perimeter or vehicle detection, and change it remotely. Changes sync to the edge automatically.

Offline store-and-forward

If a remote site loses connectivity, events are captured and logged when it reconnects — without firing stale live alerts.

Camera health monitoring

Online, offline and degraded status with history, so your perimeter doesn’t silently go dark. See camera health.

Alerts

The right alert, to the right person.

Use cases

Where perimeter detection earns its keep.

Oil & gas

Remote wellheads and pipelines

Line-crossing and restricted-area alerts on unmanned sites, with store-and-forward when the link drops.

Presence and vehicle-activity alerts when the yard should be closed.

Estates

Boundary walls and back gates

Someone crossing the boundary line raises an alert to the estate security team.

Government

Secure compounds

No-go zones around sensitive buildings, with alerts routed to the duty officer.

Construction & utilities

Plant and substations

After-hours presence detection where nobody should be on site.

Retail & malls

Restricted-area alerts on spaces the public should never enter.

Industries

Perimeter detection across industries.

Frequently asked

Perimeter detection FAQ.

Does Sorveo detect loitering?

Not yet. Behaviour detection such as loitering is on our roadmap. Today you can use restricted-area, line-crossing and after-hours presence rules to be alerted when someone is somewhere they should not be.

What is the difference between restricted-area and line-crossing detection?

Restricted-area detection flags anyone who enters a zone you have marked on the camera view. Line-crossing detection flags anyone who crosses a boundary line you have drawn, such as a fence line or gateway.

Can Sorveo read number plates at my gate?

Not yet. Number-plate recognition (ANPR) is on our roadmap. Today Sorveo detects vehicle activity, such as vehicles idling, passing or entering a zone at gates and yards, and alerts your team in real time.

What happens if a remote site loses its internet connection?

The on-site edge appliance keeps capturing events. When the connection returns, those events are replayed and logged in Sorveo without firing stale live alerts, so your history stays complete.

Will I know if a perimeter camera goes offline?

Yes. Camera health monitoring shows each camera as online, offline or degraded, with history, and outage emails can be sent to the recipients you choose for each camera.
