Inspector Kevin Mann, from the Communications Branch of the Metropolitan Police (pictured with Sonitrol's General Manager, Andrew Ward), believes in the effectiveness of smoke-generating systems: "They not only alert the neighbourhood that a burglary is taking place, they also make it very difficult for the burglar to continue. Machine-generated smoke provides a very effective security barrier in the time between the alarm being activated and the police responding."
