Shadows that move like people
Moving human silhouettes on the wall or ceiling, visible through the curtains — the sign of life a burglar looks for before choosing a house.
Keeping burglars and predators away from the people you love.

Why homes get picked
An empty-looking home is the easiest target on the street.
Dark windows, one lamp on a timer, silence in the hallway — that is what an opportunist checks in seconds, from the pavement. Kevin gives them the opposite: a home that looks and sounds lived-in, whether you are at work, on holiday, or the only one at home tonight.
The sound of a normal evening
Conversation, a TV, cooking, a dog that barks at the doorbell — played from the device, so even up close someone is clearly home.
Timers fool no one
The same lamp at the same time every night reads as automation. Kevin varies light, shadow and sound for up to four weeks without repeating.
The layer your alarm doesn't have
An alarm reacts after the door is tested. Kevin works before: from the street the house looks occupied, so the attempt never starts. Keep your alarm — put prevention in front of it.
How it works
Light. Shadow. Sound.
A burglar judges a home in seconds — by its light, its movement, its sound. Kevin delivers all three from one device, so your home looks lived-in from the street to the doorstep, and they move on to an easier target.
-
The lights come alive
Warm light shifts like real lamps and a flickering TV — never the rigid on-off of a cheap timer.
-
Shadows cross the window
Moving silhouettes pass behind the curtains — exactly what a burglar checks before choosing a target.
-
The home sounds lived-in
Voices, a TV, cooking and a dog at the doorbell play from the device — so even up close, someone is clearly home.

Plays locally — jammer-resilient
When Wi-Fi dies
Jammers blind cameras. Kevin keeps playing.
Cheap jamming devices cut cameras and app alarms off the network. Kevin plays every simulation from its own storage — no cloud, no signal, no gap.
A camera
Streams stop, alerts never send. A jammed camera protects no one — it just records nothing.
Signal lost
Kevin
Light, shadow and sound continue from local storage — the house never skips a beat.

Kevin App
Set it once. It runs itself.
Weekly schedules, geofencing that switches Kevin on when you leave, and every property in one app — so protection never depends on remembering.

Every home is sometimes empty.
Kevin moves in wherever life moves out — for an evening, a season or a semester.

FAQ
Questions, answered.
What does Kevin actually do?
Kevin is a Swiss-engineered presence simulator. Placed by a window, it plays warm light, moving human shadows and everyday sounds from its own storage, so from the street your home looks and sounds lived-in while you are away — in flats, houses, offices and holiday homes.
How is it different from an alarm or a camera?
An alarm reacts after someone tests the door; a camera records what already happened and stops working when Wi-Fi is jammed. Kevin works before any of that: it makes your home look occupied so the attempt never starts. Keep your alarm — Kevin is the prevention layer in front of it.
Does Kevin watch or listen?
No. Kevin has no camera and no microphone. It only projects light, shadow and sound. Simulations are stored on the device, not streamed from the cloud or shared with anyone.
What is included, and what does it cost to run?
One payment for the device, the app, 70+ hours of simulations and lifetime software updates. No monitoring subscription. Free shipping across the EU, Switzerland, Liechtenstein, Norway and Iceland, 30-day returns and a 3-year Swiss warranty.
Does it keep working if Wi-Fi is jammed or down?
Yes. Wi-Fi and Bluetooth are only used to set Kevin up and to install updates. Every simulation plays from the 32 GB inside the device, so light, shadow and sound continue even when burglars jam cameras and app alarms.
Is the simulation really convincing?
Galaxus tested Kevin.3 in January 2026 and called it “unrivalled in that it's an easy-to-use, all-in-one solution that delivers a truly spectacular show.” The effect is strongest where it matters: from outside, through curtains, at dusk. Placement tips are in the setup guide.
