For over 30 years, Smoke Screen has been on one mission: stop intruders in their tracks by doing something beautifully simple — taking away their ability to see.
It works. Brilliantly. A dense white cloud fills your space within seconds. Your stock is hidden. Your property is protected. The intruder can’t see anything, so they panic and leave.
No theft. No damage. No problem.
We’re trusted by retailers, warehouses, banks and businesses across the world. Our fog is food safe, non-toxic, leaves no residue, and lasts up to an hour. In short — we think it’s absolutely fantastic.
But here’s the thing nobody talks about.
There’s One Small Problem With Security Fog
When the fog goes off… you can’t see a thing either.
“I can’t tell you how many times I’ve activated a fog generator, only to walk straight into a door. Or smash my shin on a trolley.” Random burglar.
Sound familiar? Security managers stumbling into filing cabinets. Perfectly good mugs of tea knocked off perfectly good desks.
The intruder is deterred. The staff member is bruised. Justice? Partial, at best.
It’s the one limitation nobody in the industry has ever dared address. Until now.

“But if I can’t see the fog… how does it stop the intruder?”
Excellent question. We’re glad you asked.
Here is where InvisiFog’s revolutionary technology truly shines. The intruder also cannot see the fog. This means they experience a profound and unsettling sense of protection without any of the traditional dense-cloud-based deterrence they might have come to expect.
In technical terms: it’s very, very effective.
Our R&D team spent considerable time and resources developing this technology. We are confident the results speak for themselves.
(The results are, in fact, invisible. But they are there.)
