A shop that raises the alarm is good. One that defends itself is something else entirely.
Jeweller, tobacconist, pharmacy, luxury boutique, car dealership, offices: this page is here to give you honest answers. Does this sound shield belong in your premises? Where should it go? And how does it protect your team as much as your stock?
“I used to be a municipal police officer. The shopkeepers we found after a robbery never just had an emptied till: they had a team scarred for months. Anything that cuts short the assailant's time inside protects people first.” Cédric Fontaine, founder of Lima Groupe
An award-winning French innovation: Audience Award, La Nuit de la Sécurité Globale (Républik Group). Figures and facts verified in September 2026.
Let us start with the facts, each one sourced. These are not shoplifting statistics: they are robberies, night-time break-ins and assaults suffered by shopkeepers, in businesses comparable to yours.

Behind this figure, four realities familiar to any shopkeeper who has been broken into even once.
These figures stay abstract until you put a face to them. The cases below are real, and they involve businesses comparable to yours.
“He fired a few centimetres away from me”: a tobacconist held up in his own shop.

Reported by industry professionalsBusiness owners are targeted at home too: a couple tied up in the middle of the night during a home invasion.
CNEWS, September 2025 (Hauts-de-Seine)What these cases have in common: ordinary shopkeepers, at work or at home, facing violence out of all proportion to the sums at stake. What LIMA SHIELD tackles is robberies, night-time break-ins and vandalism.
Closing and opening: the two moments every shopkeeper dreads, because you are alone, exposed, with the takings or the keys. The alarm is on, the cameras are running, remote monitoring is watching. And yet, if someone forces the shutter at that moment, all your equipment just watches: what happens next is between them and you, or between them and your employee.
With a LIMA SHIELD, the scene changes twice. At night: as soon as an intrusion into the stockroom or the shop floor is confirmed, warning beeps sound, then a sound of 86 to 138 decibels makes the area unbearable, and the intruder leaves before reaching the stock. In broad daylight: the panic button at the counter triggers the device even when it is disarmed. Nobody has to step in. The shop itself puts up the barrier.
Let us be direct, because you have a security budget to allocate. There are businesses where LIMA SHIELD changes the game, and others where a different expense should come first. Here are both cases.
If you are unsure, a demonstration settles it quickly: an expert reviews your layout, your hours and your sensitive areas, and tells you frankly whether you stand to gain anything.
We protect the points intruders must pass through and the areas where value sits. One unit covers up to 100 m², standing on its base or mounted on the wall, pointed at the area to defend. The locations shopkeepers choose most often:
Large floor area, several levels, several shops? Shields are paired in the mobile app, Lima Shield Connect: each unit communicates with the others, and you control all your outlets from the same screen.
1. Disarmed: the shop carries on as normal. 2. Armed: it monitors. If an intrusion is confirmed: warning beeps, a time delay, then emission. 3. Triggered: emission is in progress, the sound alternating with pauses, can be switched off at any time by code, badge or app.
And the shortcut that matters for a business: the panic button, the remote control and the app trigger the Shield even when it is not armed. In the event of an assault in broad daylight, one press is enough. The keypad completes the set-up at the staff entrance.
A business owner's real question is not the spec sheet, it is what changes for the people who open and close every day. Here is the daily routine, from the first in to the last out.
In short: staff keep their usual routine, badge in on arrival and arm on departure, and the device only makes itself known in the situation it was bought for.
It is not a choice between your existing system and LIMA SHIELD. You keep your professional alarm, your cameras, your remote monitoring contract: LIMA SHIELD adds the active layer on top. It is AND, not OR.
In other words, no contract to cancel, no equipment to throw away. Your installation keeps its role; LIMA SHIELD takes on the one nobody was playing.
A French sound shield, winner of the Audience Award at the Nuit de la Sécurité Globale (Républik Group). When an intrusion is confirmed, it warns the intruder with a sequence of beeps, then emits a sound of 86 to 138 decibels, calibrated to the 2 to 5 kHz band, where human hearing is most sensitive, and modulated to prevent any habituation. The area becomes unbearable and triggers the reflex to flee. Without contact, without substances, without confrontation.
Behind the unit: a French startup, co-founders from the army and the police, engineers, some of them formerly at Dassault, nearly €1 million in research and development, prototypes built in Strasbourg, and compliance with European CE standards.
“Derived from military technology adapted for civilian use, this non-lethal acoustic deterrent device integrates with any existing alarm system.” Républik Group, La Nuit de la Sécurité Globale
Jewellers, tobacconists, luxury boutiques, car dealerships, warehouses, town halls and police stations are already among the first to have bought or pre-ordered.
An alarm rings, a camera records: these devices run continuously, with no consequences for anyone. LIMA SHIELD does not work that way. It stays on standby and only acts on a confirmed intrusion: it is a professional instrument, drawn from research originally developed for institutional use, then designed and regulated for civilian use.
Think of it as the device that takes over once the alarm has done its job: it only acts on a confirmed intrusion, and every activation is regulated: warning beeps, time delay, automatic shut-off. It is the tool you are glad to have on the day everything else has been breached.
| Solution | Type | During the intrusion | In practice? |
|---|---|---|---|
| Conventional alarm | Passive: detects and alerts | The siren sounds | Not much happens: noise, then waiting. |
| Cameras | Passive: sees and records | Records the scene | You get the information. Nothing more. |
| Remote monitoring | Passive: alerts and dispatches a response | Delayed response | Decent, but response times are still long. |
| Security fog | Active: conceals property | Fills the space with fog | Effective once. Open a window and it is gone. |
| Strobe light | Active: visual disruption | Flashes of light | A real impact, but highly variable. |
| Security guarding | Active: human presence | Depends on where the patrol is | Very effective, but expensive. |
| LIMA SHIELD | Active: makes intruders flee | Warning, then sound saturation | Very effective, and inexpensive. |
In the end, the best security set-ups are combinations: detection, images, a response team... and a device that takes action. LIMA SHIELD is the missing piece of your set-up.
Let us do the maths for a shopkeeper. A burglary or a smash-and-grab means the stock gone, the window or shutter to replace, the excess, a rising insurance premium, and often a day's lost trading that will never be recovered. Then comes the tug-of-war with the insurer to get paid.
And then there is what no claim form covers: a team afraid to open and close, a shaken employee who does not come back, the neighbourhood shop that becomes “the one that got robbed”. It is not just stock you lose: it is your team's peace of mind.
Set against that, LIMA SHIELD costs €2,500 excl. VAT, once, with no subscription: where remote monitoring is paid every month, this you buy once, pay off and own. It is the price of a professional instrument: nearly €1 million in research and development, a French technology. Spread over its 10-year lifespan: roughly 68 cents a day per protected zone. And we carry the long-term risk: 2-year manufacturer's warranty, battery excluded.
Manufacturer's warranty: 2 years. For 2 years, if your LIMA SHIELD develops a defect or a fault, we repair or replace it. Only the battery, a wear part, is excluded. Simply contact our support: a team based in France diagnoses the issue with you and arranges the repair or replacement. Beyond these 2 years, the device is designed to last 10 years.
LIMA SHIELD is set up in 5 to 10 minutes, on your existing system or on its own. It is produced in limited runs and is regularly out of stock.
Order LIMA SHIELDcheck availability Request a demonstrationwith a security expertThe device is pointed at the areas to protect, not at workstations. When the entrance opens directly onto the zone, the 10-second time delay gives staff time to disarm at the door, by code or badge, after the warning beeps. And even in the event of a brief accidental activation: temporary discomfort at most, no substances, business resumes immediately.
That is what manual triggering is for: panic button at the counter, remote control or app, even when the device is not armed. A response reserved for absolute emergencies, regulated like everything else: automatic shut-off, immediate disarming possible.
Yes. For indoor use, no French law known to date caps the power of an acoustic deterrent device, and LIMA SHIELD falls into a category distinct from sirens. CE compliant, its activation in the event of an intrusion falls within the legitimate defence of property (article 122-5 of the Code pénal, the French Criminal Code), with warning, time delay and automatic shut-off.
That you are adding a documented active protection measure: a CE-compliant device, traceable by serial number, with regulated activation. Your security expert can provide the technical information for your discussion with your insurer.
All your Shields, all your shops, one app: real-time status of every site, remote arming, alerts by notification. And each shop remains self-sufficient locally: detection and triggering need no network.
No Wi-Fi needed: detection and triggering are local, and the built-in 4G transmits alerts. In a power cut: internal battery up to 1 month on standby, 3 months with secondary batteries, with several deterrence cycles in reserve.
