Intruders can’t steal what they can’t see.
The smallest security fog generator on the market — firing dense, cold fog in seconds to shut a break-in down before anything leaves the building.
An alarm tells you it happened. Fog stops it happening.
A typical break-in is over in two to three minutes — long before anyone can respond. Security fog removes the one thing a thief needs: visibility.
Your alarm, a PIR or a panic button fires the unit.
Dense, non-toxic fog fills the room in seconds — no heat-up wait.
The intruder can’t see the goods, the exit, or their own hands.
Nothing to grab, nowhere to go. Most intruders abandon within seconds.
of theft attempts at fog-protected sites are stopped. A break-in is usually over in under two minutes — fog closes that gap in seconds, where an alarm only raises it.
Non-toxic, residue-light fog formulated to BS EN 50131-8 requirements. Source for the 97% figure →Watch the UNIK fill a room in seconds.
Built for the spaces other systems can’t reach.
Every UNIK benefit below comes straight from the spec sheet — no marketing maths.
Fog in seconds
No heat-up cycle. The UNIK is instantly ready and fires dense fog the moment it’s triggered — backed by two international patents on its cold-fog system.
Up to 6 months on battery
Battery-only operation is possible, with up to six months’ autonomy if mains power is lost entirely — ideal for sites with no permanent supply.*
The smallest on the market
At 300 × 200 × 150 mm and 5 kg, it tucks into spaces where larger fog cannons simply won’t fit — and stays discreet.
Safe around stock
The fog fluid is authorised for food environments — clean, non-toxic and residue-light, so it’s suited to pharmacies, food retail and stockrooms.
Very low running cost
Power draw is close to zero, and a single fluid bag delivers between two and eight full shots — keeping the cost per activation low.
Remote monitoring, free
Add the optional ActiveCloud board and you get remote monitoring and activation through the cloud at no subscription cost — with Active Server ready too.
Where the UNIK earns its place.
The UNIK is designed for relative-risk premises — smaller, often unmanned or mobile spaces. For larger floorplates, the Compact or HP Line scale up the same protection.

From trigger to total obscuration in seconds.
Detect
An intrusion is detected by your alarm system, a PIR sensor or a hold-up button.
Fire
The signal triggers the UNIK through one of its inputs or panic input — instantly, with no warm-up.
Fog
Dense cold fog floods the protected area — up to 600 m³ of commercial coverage per cartridge.
Alert
With ActiveCloud fitted, you’re notified remotely and can monitor or activate the unit from anywhere.
Not all security fog is equal.
Already have an alarm?
The UNIK is designed to integrate with intruder & hold-up alarm systems through its three inputs, outputs and PIR/panic input — adding a physical deterrent on top of detection.
Works alongside your existing setup, including the Ajax platform.
