St. Louis businesses using fog machines to fight crime
St. Louis, Missouri businesses will be installing fog machines as a way to prevent smash and grabs.
Within seconds of thieves showing up, the machine fills the room with fog. That makes it impossible for the crooks to see.
The system is already very popular in the United Kingdom and works better than an alarm system.
Each fog machine costs roughly $7,000.
The system can be fired up remotely and keep a room foggy for hours.
