PRAESIDIUM

In the gilded corridors of London's luxury retail—from Sloane Square's bespoke ateliers to Knightsbridge's iconic emporiums—Praesidium fog systems stand as the pinnacle of non-lethal intrusion defense. Upon activation, our ultra-dense, glycerin-based mist floods your space in a controlled, odorless veil, reducing visibility to mere 50cm and disorienting assailants within seconds. This engineered haze, compliant with EN 50131-8 standards and free of corrosive residues, safeguards your £100K+ vitrines without a trace—halting 97% of smash-and-grabs per UK trials, while preserving the pristine ambiance that defines your brand. Unlike intrusive alarms that summon chaos, Praesidium empowers quiet resolution, minimizing staff trauma and operational disruption in high-footfall sanctuaries.

Time is the thief's ally in a smash-and-grab, where opportunists vanish with £15K-£50K hauls in under 90 seconds—yet Praesidium counters with surgical precision, unleashing full-room fog coverage in just 6 seconds from trigger. Our advanced generators, calibrated for 150-300m² boutique layouts, propel non-toxic mist at 120°C nozzle velocity, saturating key zones like display cases or cash areas while sparing exits for safe egress. This rapid escalation, tested to PD 6662 compliance, buys 3-5 vital minutes for response teams, with fog persisting 30-60 minutes before natural dissipation—no ventilation needed, no cleanup on delicate fabrics. For elite retailers, this instantaneous barrier transforms fleeting threats into futile retreats, ensuring your legacy endures unscathed.

Praesidium operates with the subtlety of a whisper, yet the force of a fortress—empowering your team through a single, discreet panic button mounted beneath the till or concealed in a fob. Our smart, discreet engineers handle every aspect of installation, seamlessly integrating units into your shops architecture with precision and minimal intrusion, ensuring flawless performance without visible traces. Custom zoning directs mist precisely to high-value perimeters, triggered solely by your staff's one-touch command—fully trainable in 5 minutes. Maintenance? Bi-annual cartridge swaps and on-site diagnostics ensure 99% uptime, with London support. In your refined retail realm, operation is intuitive elegance: One button press restores order, without the clamor of sirens or the scars of confrontation.

Every Praesidium system is individually designed to mirror the sophistication of your retail space — elegant, intelligent, and precise. Our fog security installations integrate seamlessly with interiors, protecting collections without visual intrusion or operational disruption.

Each project begins with a private consultation and site assessment. From compact boutiques to multi-floor flagships, we design complete protection around your layout, coverage zones, and aesthetic needs.

Our pricing is tailored to specification. Core fog units are available for outright purchase or discreet hire, with installation, maintenance, and refills provided as part of an ongoing service relationship. Every detail — from cartridge placement to activation timing — is calibrated to your store’s rhythm.

We offer private demonstrations using our handheld mini fog device, allowing you to experience a six-second deployment within your own space before commissioning.

Praesidium protects London’s leading luxury retailers, achieving over 97% deterrence rates and delivering measurable peace of mind — quietly, beautifully, without compromise.
