Most break-ins are over in less than four minutes. A good police response takes at least ten. Tesco losses were substantial: fast acting thieves were stealing from petrol filling stations and Express stores with impunity.
Options
All conventional types of security had been tried. None were successful in stopping the losses.
Solution
Smoke Screen by Concept Smoke Screen. These images are taken from genuine CCTV footage captured in a Tesco petrol filling station in Manchester, England. A monitored alarm, roller shutter door, CCTV - nothing prevents these two thieves, intent on stealing cigarettes from behind the counter, from breaking and entering. Then Smoke Screen is activated and the burglary is finished (literally) in a few seconds.
Little wonder that Tesco went on to install Smoke Screen into over 400 sites throughout the country. The 'smoke' produced is harmless and guaranteed not to leave any form of contaminating residue. It stops thieves by taking away their ability to see - thieves can't steal what they can't see.
Smoke Screen has proven to be one of the most successful security solutions on the market.
