A jewellery raid is measured in seconds. Glass smashes, hands reach for display cases, stock vanishes. The window between threat and loss is razor-thin—often under 60 seconds. Fog-based security defeats this by filling the entire shop space in those same seconds, rendering the space unusable and the raid futile.
Why jewellery shops are soft targets
Jewellery is high-value, portable, and on display. A single bracelet can represent hours of legitimate profit. A watch or ring is easy to conceal and easy to sell. Raiders know that alarm response takes minutes. They count on having 30–60 seconds of clear visibility to grab stock and leave. They’re wrong if fog is installed. This is why fog is a proven defence for jewellers.
Window displays add risk. Stock behind glass looks undefended. Organised retail crime gangs scout targets in advance. They study staff routines, shift changes, and peak trading hours. When they strike, they expect to operate in clear sight for long enough to grab the best items from open displays and smash into cases.
Traditional alarms only deter after the fact. Police arrive too late. Fog stops the raid before it begins. As part of a comprehensive approach to stopping smash-and-grab and ram-raids, fog is the fastest-acting layer of defence.
How fog stops a raid in real time
A glass-break sensor or door contact triggers the alarm. Fog is released instantly. Within seconds, a dense cloud fills the shop. Thieves cannot see. They cannot locate stock. They cannot tell one display from another. They cannot move safely.
The raid collapses. Most attackers abandon within seconds.
This happens before a single item leaves the shop. The fog forces them to either wait for it to clear—by which time police are on the way—or give up.
97% of thefts are avoided with a fogging system AND an alarm, compared with 17% with an alarm only. Density® manufacturer figure.
The UNIK advantage: instant fog, zero delay
Most fogging systems need mains electricity. They pressurize and discharge over 10–30 seconds. That delay is fatal in a raid. The UNIK fog system is battery-powered. It deploys in under 2 seconds. For a jewellery shop, this speed difference is everything.
UNIK covers up to 600 cubic metres. A typical high-street shop fits within this range. The battery holds a full charge for up to 6 months on standby, so the system is always ready. No reliance on mains power means no single point of failure.
During a power cut, UNIK still works. Some intruders expect alarm systems to fail when the lights go out. They’re wrong. Battery systems protect shops when thieves think they’re safe to strike.
The system requires zero heat to operate, which means safer deployment in tight retail spaces and no risk to goods or customers.
Integration with your existing alarm
Fog alone is not enough. The 97% figure applies when fog and alarm work together. The system integrates with all existing alarm panels. It works with hardwired legacy systems. It works with modern wireless platforms like Ajax.
Your door contacts, glass-break sensors, and motion triggers on your current alarm do the detection. The fog system wires into the same circuit. When an alarm condition is met, fog deploys automatically. You don’t reprogram anything. You don’t replace anything. It bolts onto what you already have.
Remote monitoring via ActiveCloud means you see events in real time on your phone. You see the alert the moment it happens. You can review footage from cameras linked to your alarm system and understand exactly what triggered the deployment.
Compliance and safety
The system meets EN 50131-8:2019, CE, EMC, and FCC standards. The fog fluid is non-toxic. Eurofins has tested it to EN ISO 16000-1:2006. It is certified for food-contact environments under Reg. (CE) No. 1935/2004.
If your shop includes a café or hospitality counter, the fog is safe to use. The residue won’t damage displays. It won’t contaminate food or stock. It won’t harm customers in nearby areas. You can operate a secure jewellery shop and serve refreshments without conflict.
Assessing fit for your premise
A security survey calculates the exact cubic-metre volume of your shop. It includes storage, office, and display areas. The survey determines whether one system is enough or if multi-zone deployment is needed. It identifies the best placement for the generator.
Most high-street jewellery shops fit within the UNIK or Basic 390 ranges. Larger premises may need the 600 Lite or Density 900. For very large shops or those with multiple storey levels, larger generators like the HP6000 are available.
The generator stays out of public sight. It sits in a storage room, office, or secured back area. Wiring runs concealed through walls or cabling ducts. The system is invisible to customers and to potential thieves who might scout the premises beforehand.
Frequently asked questions
Will fog trigger my fire alarm?
No. The fog is non-toxic. It does not activate smoke detectors. The system is built for occupied retail spaces.
Can thieves disable the system?
The generator is hidden. Wiring is concealed. To disable it, a thief would need to know exactly where it is and how it’s wired. A typical raider doesn’t have that knowledge.
How long does visibility remain obscured?
Fog density peaks in 10–15 seconds. It stays dense for 15–20 minutes in a sealed space. In a typical high-street shop with external doors, air movement reduces density after 5–10 minutes. This is long enough to stop any raid and allow police to arrive.
What about false alarms?
Modern alarm logic cuts false alarms. Multi-sensor verification is standard. For example, the door contact plus motion detection, or glass break plus movement within 10 seconds. You control the settings.
Is the system compatible with security cameras?
Yes. Fog deployment triggers your alarm. Your alarm can trigger recording or alerts in your VMS. Most modern camera systems support this integration.
If your jewellery shop is currently protected only by a traditional alarm, a security survey will show whether fog deployment is right for you. The survey assesses your premises. It calculates the coverage you need. It confirms your alarm will work with the fog system. It provides a detailed quote.
