A burglary protection that strikes back and actively prevents merchandise from being stolen. This operates so that if a burglary is indicated in for example a shop, within a few seconds, an opaque grayish white smoke spreads out and fills parts or the whole room within about 10 seconds. There is no possibility of scattering the smoke and the smoke expansion can continue for 10 minutes or more. At an embodiment, smoke producers are used, which contain a compressed gas and the smoke liquid which is normally at the same temperature as the surroundings. The smoke liquid is heated directly and quickly to vapour by electronic heating at high effect and spread via nozzles.
