LiDAR: an invisible laser curtain
A plane of light in front of what matters most — the glass wall, the cellar, the wall coping. It measures the true size of whatever crosses it, which is why it can ignore a cat and catch a person crawling.
What makes it unique
Real size, not a guess
It knows each object's range and angular width, so thresholds are set in centimetres, zone by zone. The only technology in our palette that measures size rather than estimating it.
Right against the facade
The plane stands centimetres from the glass or the wall: a clean cut at the boundary, no overreach into the neighbour's plot, no dead zones in front of the protected surface.
Safe and invisible
Class 1 laser — no eye hazard, no mandatory signage. Nobody sees where the curtain is; that is part of why it works.

Frequently asked questions
How much does a security LiDAR cost?
It is a critical-plane technology, not general surveillance, and is sized by the plane to protect. The fixed price comes after the visit; for open ground, radar usually pays off better.
Is LiDAR dangerous to the eyes?
No: the units we install are Class 1 laser, the lowest classification, the same category as a household CD player. No signage required.
Does it protect a picture window or a glass facade?
That is its star application: it raises a plane of light centimetres from the glass, detecting any approach before the surface is touched.
Can it ignore a cat and detect a person?
Yes, because it measures the object's real size from its angular width and range. The threshold is set in centimetres and per zone — no infrared beam does that.
How is it different from an infrared beam?
A beam watches a line between two points; LiDAR watches a whole plane and measures size by zone. It is more selective and harder to defeat.
Does LiDAR work in fog or heavy rain?
It degrades by physics: scattering absorbs the pulse. Filter modes mitigate but do not eliminate it, which is why it is used as a critical plane inside a layered system.
Can a virtual wall be set above the real wall?
Yes: it is a typical application, a vertical plane at the wall coping that warns of a climb attempt.
Does it protect the boundary without overreaching into the neighbour's plot?
Yes, and it is an advantage over radar: the cut is clean at the plot line, without capturing the neighbouring ground.
How many zones can a LiDAR watch?
Reference units allow up to 8 independent zones, each with its own sensitivity, minimum object size and configurable output.
Does it detect a small object thrown through the plane?
Security units detect objects on the order of 2 cm crossing the plane, depending on the sensitivity mode.
Does it need installer software?
Yes: object size per zone is configured in the installer software, which is part of our commissioning work.
Can you see where the laser curtain is?
No: it is invisible, and that is part of its effectiveness. There is no visible barrier for an intruder to locate and bypass.
Is it worth using for the whole garden?
Not cost-effective: for general area, radar covers more for less. LiDAR earns its place where one plane needs centimetre precision.
Is there a model for large outdoor areas?
Yes: a larger 30 × 60 m, 190° model with fog/snow mode and EN 50131 Grade 3 certification, for cases that require it.
Does LiDAR replace the camera?
No: it detects precisely, but the AI camera provides the image that verifies and serves as evidence. They work together.
What is a security LiDAR?
An invisible laser plane that measures distance at every angular step using a rotating mirror. The unit learns the background profile and detects any deviation from it — and because it knows both range and angular width, it computes the real size of the object.
Is the laser safe for eyes, children, pets?
Yes: the units we install are Class 1 — the lowest laser classification, the same category as a household CD player. No warning signage is required.
Where does it make most sense at a home?
In front of a glass facade or a row of terrace doors — an invisible laser barrier for windows and the terrace, security for a glass-fronted house — along the top of a wall (a virtual wall above the real one), on a narrow boundary strip where radar would overreach into the neighbour's plot, or protecting a cellar or a wall with artwork.
Does fog or heavy rain affect it?
Yes, by physics: scattering absorbs the pulse. Filter modes mitigate but do not eliminate it — which is why LiDAR serves as a critical plane inside a layered system rather than as a lone outdoor layer.
Why not use it for the whole garden?
Cost-efficiency: for general area surveillance, radar covers more for less. LiDAR earns its price where one specific plane needs centimetre precision.
LiDAR
LiDAR measures real size, it doesn't guess it
Where millimetric precision is needed — a glass facade, the plane of a wall, a gate — the LiDAR curtain raises an invisible laser plane and measures the distance to every point many times a second. Because it knows the geometry of the background, it knows to the centimetre when something appears that was not there before, and what real size it has.
That allows what a conventional alarm cannot: deliberately ignoring a cat crossing while firing on a person approaching the glass. The threshold is set by zone, so an animal's low passage does not count and an adult body does. In a your area home with a garden and wildlife, that difference is what keeps the system from crying wolf at night.
LiDAR is Class 1 — as eye-safe as a CD player — and needs no light, so it works the same by day or in total darkness. It is the fine layer that complements radar on the planes that demand exactness.
Coast and materials
Salt eats badly chosen systems
Near the sea the silent enemy is not the intruder, it is corrosion. The ISO 12944 standard classes the coastal environment as C5 (“very high” corrosivity), and in that category a poorly chosen bracket or housing can degrade in a few years what lasts a decade inland.
That is why in your area the choice of materials is no detail: stainless steel of the right grade, enclosures and ingress ratings meant for salt and damp, and a mounting that creates no rust points. A security system that rusts stops being security.
The same goes for electrical protection: near the coast and on high ground, storm surge is real, and one strike can take out an entire system. Surge protection is not an extra — it is what makes the system last.
Zoning
Zoning: making an alarm say where
A house protected as a single block can only say “something is happening”. A house divided into zones says “someone is on the north line, by the pool”, and that difference is what lets you decide in seconds instead of stepping out blind.
We divide the your area plot into logical zones — perimeter, garden, access points, the immediate surround of the house — and each has its own rule: what is watched, at what hour, at what sensitivity. At night the outer perimeter can be armed while you move around inside; when away, everything. The same installation protects differently depending on the moment.
Zoning also narrows the alert: instead of one sensor tripping on everything, each zone reports separately, and the image tells you exactly where to look.
Access points
The weak point isn't the fence — it's the gate
In most homes the intruder does not climb the highest wall; they come in where there is already a gap made for coming in: the vehicle gate, the service door, the gardener's or the pool access. These are the points legitimate people use every day, and precisely for that reason the worst-watched.
In your area we treat those accesses as zones in their own right: detection that tells the expected passage from the one that is not, image verification of who arrives, and a record of every opening. The point is not to turn your home into a bunker, but to know who comes in when you are away, and to make sure an open service door is not an invisible hole.
Where there is domestic staff, maintenance or frequent deliveries, this is the layer that turns a normal flow of people into something traceable, with no friction for you.
The alert
What happens, exactly, when the alert fires
A good system is not judged by what it does at rest, but by what happens in the ten seconds after a real detection. The moment two layers agree there is a person where there should not be, the sequence starts: an alert to your phone with the image of that moment, a recording of the zone, and — if you choose — active deterrence with lighting and siren.
You get a photo, not an anonymous buzz: you see whether it is the courier, the gardener or someone you don't recognise, and act with judgement instead of panic. In your area, where many homes are watched from a distance, that image is the difference between calling for nothing and calling with reason.
And the recording stays: an image obtained correctly, framed within your property, is usable evidence. The system does not just scare the intruder — it documents what happened.
