Security Fog Systems for Car Showrooms & Dealerships
High-value showrooms are overnight targets for organised gangs. Density's security fog solutions are approved for use with NSI and SSAIB security systems. Fog begins discharging in under one second after a confirmed trigger; zone obscuration depends on the system and site specification.

Overnight Showroom Raids:
High-value vehicle showrooms are systematically targeted by organised criminal networks operating in the early hours. Standard alarm systems give intruders minutes to locate key safes, steal vehicles, and remove high-value parts before any response can arrive.
Key Safe & Parts Theft:
Beyond vehicle theft, dealerships face significant losses from targeted key safe raids, parts store break-ins, and theft of accessories and diagnostic equipment — all of which can be completed in under three minutes by a practised team.
Insurance & Manufacturer Compliance:
Density is approved for use with NSI and SSAIB security systems. Your insurer or broker must confirm the security requirements and terms of your individual policy; product documentation is available to support that discussion.

Security Fogging — How It Works
Comprehensive Security for Car Dealerships & Showrooms
Car dealerships present a uniquely attractive target for organised criminal networks. High-value vehicles, accessible key safes, lucrative parts stores, and large, open showroom floors combine to make dealerships one of the most systematically targeted business types in the UK. The problem is compounded by the geography: extensive glazed frontages that offer visibility, loading areas and parts stores at the rear, and peak risk periods that coincide precisely with the hours when the premises are empty and response times are longest. CCTV and alarm systems are essential components of any security strategy, but they are passive tools — they record and alert; they do not stop.

Why Dealerships Choose Active Deterrence
Car dealerships lose millions each year to overnight raids that are completed before the first police unit can respond. Traditional alarm systems create a notification of the intrusion; they create no barrier to it. Density fog closes that gap — the moment an intrusion trigger is confirmed, a dense physical barrier fills the protected space, making it impossible for a raider to locate a key safe, reach a target vehicle, or navigate the showroom to the exit with anything of value.
-
Instant area saturation
Density security fog starts discharging in under one second after a confirmed trigger. The time needed to obscure a zone depends on the model, protected volume, layout and ventilation, and is confirmed during the site survey.
-
Seamless alarm integration
Density connects to your existing alarm panel or monitoring station via a standard relay output, with no new infrastructure required. Installation is typically completed within a single working day.
-
Motor trade deterrence effect
Active fogging systems are increasingly recognised within the motor trade as a primary deterrent — criminals targeting dealerships are aware of these systems and their effectiveness, with many raids abandoned on detection.

Yes. Multiple Density fog generators can be deployed across separate zones — showroom floor, parts store, service area, key cabinet room — each triggered simultaneously or independently depending on your alarm configuration.
A site survey will map each zone's dimensions and ceiling height to ensure the correct unit specification and placement for complete coverage across every area you need to protect.
Density integrates via a standard relay output on your existing alarm panel. This is compatible with the vast majority of alarm systems used across UK motor trade premises.

Yes. Density fog generators are engineered to fill spaces effectively regardless of ceiling height up to 4 metres — which covers the majority of UK motor trade showrooms.
Density security fog starts discharging in under one second after a confirmed trigger. The time needed to obscure a zone depends on the model, protected volume, layout and ventilation, and is confirmed during the site survey. The C-Line range specifically is built for coverage of volumes of up to 2,400 m³ per unit.
Installation costs are calculated on a per-site basis, taking into account the number and size of zones to protect, ceiling heights, and the complexity of integration with your existing alarm system. A free site survey — provided at no charge and with no obligation — is the most accurate way to produce a costed proposal for your specific dealership.
A Density installation is typically weighed against the cost of a single incident — stolen vehicles, keys and stock, plus the downtime and the risk to cover — rather than against any promise about premiums.
