Garages and Classic Cars: the ultimate protection against vehicle theft

The methods used in luxury car theft have changed dramatically. Thieves no longer tamper with alarm systems on the street: they break into the garage directly whilst the owner is asleep. The mouse jacking — signal relay theft of the electronic key — has become the most common method of operation for premium vehicles.

But garages have one feature that thieves often overlook: they are enclosed spaces, ideally suited to protection by Density fog machine. A standard double garage can be filled up in a matter of seconds by a Density Air, making it physically impossible to manoeuvre the vehicle.

Mouse jacking: understanding it to better protect yourself

Mouse jacking (or relay attacks) amplifies the signal from the vehicle’s key fob from inside the house, tricking the vehicle’s sensors into thinking the key is nearby. The car unlocks and the engine starts without the owner even getting out of bed.

What makes this technique particularly dangerous is that it does not require any physical break-in of the car. The only protection required is therefore that of the the area where the car is parked — typically, the garage.

This is exactly where the fog generator comes into play. If a thief breaks into the garage, the alarm system detects the intrusion and activates the generator. Within seconds, the space is filled with fog. To understand how it all works, read how an anti-intrusion fog generator works.

Density Air: the perfect solution for homeowners

Le Density Air is the Density model, designed specifically for domestic use and small spaces of up to 40 m². It produces 400 m³ of mist in 45 seconds — more than enough to fill a double garage.

Its key selling point in a residential setting: it is available in 7 façades (White Marble, Wood, White, Blue and Gold Cloud, Black, Mediterranean Sea, Black Marble). Installed in a carefully fitted-out garage, it could easily be mistaken for a design feature rather than a safety device. Density also offers a specific advice for individuals.

What about a larger garage or a collection of several vehicles?

For enthusiasts with a garage that can hold 3 to 5 cars (50 to 100 m²), the Density 900 is the recommended option. It covers up to 100 m² with a ceiling height of 3 metres.

For a genuine private showroom or a collection housed in a dedicated building (200 m² or more), the Density 1500 IP with a native IP card enables remote monitoring via the Cloud Density.

In short: whatever the size of your garage, there’s a Density model to suit your needs. A compact space + a single exit = the ideal conditions for maximum fog efficiency.

Conclusion

The garage is the blind spot when it comes to home security. The Density Air, with its ability to immobilise a car in a matter of seconds, is the only active security measure capable of intervening before a thief can drive off in your vehicle. For car enthusiasts who own valuable vehicles, it has become as standard a piece of equipment as a perimeter alarm.
