A system and a method for operating an intruder deterrent system by which a smoke screen is generated in response to an intruder being detected, a smoke screen generator operatively linked to the intruder detecting. To achieve an intruder deterrent system that can operate for a longer period after interruption in the power supply, latent heat is stored in a heat storage, and smoke can be generated by transferring the latent heat from the heat storage to a liquid, which liquid is evaporated. The use of the heat storage has led to the unexpected result that the smoke generator can operate independently of power to the heating elements for a very long period.

The present invention relates to a fog-generating device comprising a reagent (1), ignition means (2), a reservoir (3) containing a fog-generating material (4), and a heat exchanger wherein gas generated by ignition of the reagent (1) drives fog-generating material from said reservoir to said heat exchanger. Further it relates to a removable housing for a fog-generating device comprising a reagent and a reservoir containing a fog-generating material, wherein in that said removable housing further comprises means to allow transmission of an ignition signal from said fog-generating device to said reagent. The invention further provides the use of said device and / or removable housing for the generation of fog, in particular to protect against intruders and physical treat by persons. In a particular embodiment, the fog-generating device of the present invention or the removable housing therefore comprises depressurizing means (18). Depressurizing means allow the escape of gas from the device so that the pressure inside the device is reduced and becomes closer to atmospheric pressure.
