Upper floor
Barricaded person, somewhere above
Which floor, which door, what is on the landing. Known before anyone climbs.
Indoor reconnaissance for tactical units
Calm eyes on the next floor.
Before your team takes the stairs, Serrin does. It flies up the stairwell in the dark, without GPS, and the team leader watches the live view and a growing floor plan on one tablet.

Everything the team leader needs. On one screen.
Live video on the left, the floor plan on the right. The plan grows with every room Serrin passes, one floor at a time, so the team knows the layout before the first step.
Point, don’t steer
Serrin holds its position and keeps its distance from walls on its own. The operator chooses where it goes next. It feels like pointing, not flying.
Built for the stairwell
Landing to landing, floor to floor. A throwable robot stops at the first step. Serrin starts there.
No light. No GPS. No plan.
It navigates with its own sensors and brings its own light. You don’t need building plans in advance, because Serrin draws them.
One mission file
Video and floor plan are saved together. For the debrief, for the report, and on your unit’s devices, not in someone else’s cloud.
Why the stairwell
Every floor above is a floor nobody has seen.
Today’s kit covers one room at ground level. Everything above means sending people first. Serrin is built for exactly that gap.
Made for the places you can’t see into.
Three situations tactical units describe to us again and again. In each one, the first look decides how safely the rest goes.
Building search
Alarm in a large building
Stairwells and corridors cleared floor by floor while the team holds the entrance.
Below ground
Basements and underground garages
No GPS, no daylight, no signal from outside. Exactly where Serrin was designed to work.
A flight, from case to debrief.
Serrin fits into how your unit already works. The team stays in cover, the operator stays at the door, the aircraft goes first.
01
Out of the case
Carried in the patrol car. Switched on at the stairwell door.
02
Launch from cover
The operator starts it from the door. Nobody enters yet.
03
Up, floor by floor
Landing by landing. Each floor appears on the tablet as a plan.
04
Hold and watch
It holds position on a landing while the team leader decides.
05
Debrief
Back in the case. Video and plan are one file for the report.
We measure against what you carry today.
One number decides whether Serrin earns its place in the vehicle: the time from opening the door to a complete floor plan. Your building, your operators, lights off.

Serrin Indoor
Small enough for doors and stairwells, light enough to ride along in every patrol car.
In development
- Use
- Building clearance, barricaded persons, basements
- Navigation
- Own sensors, no GNSS, works in darkness
- Output
- Live video and a floor plan per level
- Weight
- Target under 1 kg
- Link
- Through several interior walls. Range published after the first trials
- Data
- Stored with the unit. No cloud account required
Components you can audit
Core components from allied suppliers only, documented part by part.
Your data stays yours
Recordings live on your devices. Nothing leaves the building unless you export it.
Ready for procurement
Spec sheet, test reports and documentation from the first pilot on.
Tested by operators
Every version is judged by the people who use it. Not by us.
Serrin Dock
The second aircraft lives on the roof. Same app, same mission file, same training.
Planned · after Serrin Indoor
Stationed on rooftops across the city. When a call comes in, it launches to the address and streams the first picture while units are still on their way.
We build it second, once Serrin Indoor has proven itself with pilot units.
Questions units ask us
Does Serrin need GPS or building plans?
No. It navigates with its own sensors and draws the plan while it flies.
How far does the link reach inside a building?
That is exactly what the first trials measure. We will publish the measured range instead of a promise.
Where is the video stored?
On your unit’s devices. Nothing leaves the building unless you export it.
Can we test it before buying?
Yes. That is what the pilot programme is for: your facility, your scenarios, your operators.
When will it be available?
The first pilot units fly with Serrin in 2027. Wider availability follows once the trials are done.
Pilot units wanted.
We are looking for two or three tactical units to test Serrin in their own facility and tell us where it fails. We are also hiring flight hardware engineers and people who have served in a tactical unit.
