Your stockroom and workshop are targets. While customers browse the showroom, thousands of pounds in bikes, parts, and tools sit unguarded in the back. Thieves know exactly where this inventory lives. They plan their entry route. They work with precision and speed. Locks and closed doors, even solid ones, don’t reliably stop determined burglars.
You need multiple layers of protection working together. Locks, reinforced doors, gates, and alarms all contribute. But adding one more layer—active deterrence—fundamentally changes the equation. It stops theft in real time.
Why Stockrooms and Workshops Are Vulnerable
The numbers matter. In the UK, approximately 49,000 bicycles were stolen in 2025. The average loss per theft: £487. But your workshop inventory exceeds just finished bikes. You hold wheels, frames, drivetrain components, suspension units, and specialist tools. A single organised break-in can clear tens of thousands in stock value.
Workshops and stockrooms face unique vulnerabilities:
- Staff attention concentrates on the sales floor; back areas remain largely unseen
- Fewer and more predictable entry points than the showroom—burglars know exactly where to attack
- Darkness and isolation after hours, particularly in business parks or industrial locations
- Portable, high-margin goods that move quickly through secondary markets
Most break-ins occur during evening and night hours when your premises are closed or operating with minimal staff. Professional thieves arrive with knowledge of your layout. They work with speed and coordination. Once inside, your ability to respond is essentially zero.
The Limits of Locks and Lights
Solid doors, reinforced locks, and motion-activated lighting do help. They present friction and may discourage casual opportunism. But professional burglars arrive well-equipped. They carry specialist entry tools, they conduct surveillance of your premises beforehand, and they operate in coordinated teams. Locks and lights alone cannot reliably defeat this level of determination.
Alarm systems add significant value—police dispatching and the psychological awareness of monitoring both matter. However, alarms operate within a critical time window. Between the moment the alarm triggers and the moment police arrive, a prepared thief typically has several minutes. In a workshop packed with portable, high-value inventory, those minutes are usually sufficient to collect and remove goods.
97% of thefts are avoided with a fogging system and an alarm combined, compared with 17% with an alarm alone. Density® manufacturer figure. The difference is active deterrence: instant, overwhelming, inescapable.
Active Deterrence: Fog as a Stockroom Guardian
Security fog fills a room with thick, inert mist in under 60 seconds. When a door or window is compromised—or motion is detected inside a locked space—the fog deploys automatically and immediately. Visibility collapses to near zero. The intruder cannot navigate the space. They cannot locate your inventory. They cannot identify exits. Coordinated teams lose the ability to communicate and function. Most abandon the attempt within seconds.
The fog is entirely safe. It is non-toxic and certified for use in environments where food is present (complying with Reg. (CE) No. 1935/2004). It presents no hazard to staff or customers even if accidentally triggered during operating hours. The fog disperses naturally within several hours, leaving no residue and causing no damage to bicycles, components, or tools.
For a bike shop stockroom, this represents a fundamental shift in security posture. Your high-value inventory is now protected not simply by barriers and detection, but by active incapacity—the moment an unauthorised entry occurs, the perpetrator’s ability to function is neutralised.
Integration with Your Existing Systems
You may already operate an alarm panel, CCTV system, or access control infrastructure. Fog integrates directly with all of these without conflict. The system is fully compatible with all existing alarm panels and demonstrates complete compatibility with Ajax and other modern platforms. Remote monitoring via ActiveCloud provides real-time notification the moment a breach is detected.
The most effective security architecture combines multiple independent layers. Door and window sensors, professional alarm monitoring, CCTV recording, keycard access control, and fog deterrence all contribute distinct value. Fog stands apart as the only layer that halts theft in real time, operating at the moment of intrusion rather than serving only as a post-incident record or delayed deterrent.
Sizing and Deployment
Coverage is measured by room volume in cubic metres (m³), not floor size. A typical workshop or stockroom is 50–150 m³. The UNIK system is the smallest and fastest option. It covers up to 600 m³ and deploys in seconds with no heat. For large warehouses, the HP range goes up to 14,000 m³.
Setup is simple. The generator hides out of sight. A sensor at the door, window, or inside the room triggers the fog when a break-in happens. The fog spreads throughout the space and keeps working for several hours.
The Business Case
One break-in costs £2,000 to £10,000 in lost stock. Add insurance excess and downtime. Add the stress of it happening again. A good security setup—with fog—pays for itself quickly through fewer losses and sometimes lower premiums.

Frequently asked questions
Will fog damage bikes, components, or tools?
No. The fog is safe and leaves no residue. It’s certified by Eurofins and meets food safety rules. It clears in hours and won’t harm paint, rubber, or metal.
What happens if fog deploys accidentally during working hours?
It’s safe. The fog won’t hurt staff or customers. They simply leave the area and it clears naturally. This rarely happens if sensors are placed only at entry doors.
Can the system work with my existing alarm panel?
Yes. Fog works with all alarm panels. Link the sensor to the generator and it deploys when the alarm goes off. It also works with Ajax and other modern systems.
How long does the fog stay in place?
The fog is effective for 2–4 hours depending on room size and ventilation. It clears slowly, giving full protection during the critical early minutes after a break-in.
Is this suitable for a small workshop as well as a large stockroom?
Yes. UNIK covers up to 600 m³ and works for small to medium workshops. Larger spaces may need larger systems. A survey finds the right size for your needs.
Protecting your workshop and stockroom needs more than one tool. Combine solid doors, alarms, access control, and instant fog, and you make a break-in too risky.
