For security & response teams

See what is flying near your sites, before it reaches you.

You are responsible for keeping people and places safe, and the part of the picture you cannot see is the part that is broadcasting right now. FORSYTE puts that picture on the phones your team is already carrying.

Runs on Android phones you already ownWorks offline, no cloudPassive sensingBuilt by an ex-British Army EW founder

The kit that detects drones costs £50,000 to £250,000 a site, so most teams have nothing. OpenARC runs free on the phones your people already carry, and shares every detection across the whole team.

Who it's for

Built for people who need to know what is transmitting around them.

Security

Venues and sites under Martyn's Law duties.

Police & public safety

Officers on cordons, events and patrols.

Search & rescue

Teams working where there is no infrastructure.

How it works

Three steps, no procurement cycle.

Put it on the phones you have

Every phone on the team becomes a node. There is nothing to mount, nothing to power and nothing to wait on.

It listens and works it out on the device

Passive sensing, classified on the handset itself. Nothing is sent to a cloud service, so it keeps working when the connectivity does not.

It tells the team, out loud

Alerts are spoken in plain English, and what one device hears is shared with the rest of the team on the map.

What it hears

The activity you currently have no way to see.

Drones broadcasting Remote ID

Aircraft nearby that are transmitting a Remote ID beacon, shown on the map as they are heard.

GPS and GNSS interference

Conditions consistent with jamming of the navigation signals your own team depends on.

Unknown wireless activity

Transmitters in the bands you care about, logged with time and signal strength for the report afterwards.

Your own coverage

A shared picture of where your team is, so the map shows both what was heard and who heard it.

FORSYTE observes and classifies radio activity. It does not transmit to interfere, it does not decode message content, and a detection is a report of what was heard, not a confirmed identification. Detection range and reliability depend on the hardware, the environment and the conditions on the day.

Free, and not free

The app is free. The things around it are how we make money.

We are not going to charge a security team for the thing that keeps their people safe on the ground. OpenARC stays free. What costs money is everything that turns it into an organisation-wide system.

The command center

The desktop side, for the person watching the whole picture rather than carrying a phone around a site.

Control room integration

An API into the systems you already run, so detections land where your operators are actually looking.

Custom builds and changes

Your workflow, your symbology, your reporting. Built to how your teams already work rather than around them.

Training

Getting a whole team confident with it, not just the one person who volunteered.

For suppliers and resellers

You are already selling them the hardware.

If you supply phones, tablets or rugged devices into security companies, you are competing on price with everyone else selling the same handset.

Put OpenARC on it and you are not selling a phone any more. You are selling a mesh awareness and shared mapping system that happens to arrive on hardware you supply, with the command center, the integration and the training sold behind it.

Same devices, same customers, a different conversation and a different margin.
