 It was becoming clear how the brave and expert thieves pulled off the world's biggest gem 1 robbery. From a flight of stairs in the diamond center car park, they used a stolen key to open the door leading to the vault 2, and there they somehow managed to defeat the battery of the security equipment. They were expert thieves.


-In the safe room, you have light detection, motion detection, heat detectors 3, and a enormous safe door with a code and an alarm system on it.
 
It turned out that everyone of these devices could be easily undermined. The light level sensor 4 was covered with a black tape. The video cameras inside and outside of the vault door were shrouded 5 with plastic bags. The motion sensor was covered with thick spray. Eliminating one security device after another, they got to the vault door. On the other side laid enough diamonds to fill a small swimming pool.
-It's an enormous safe door with an alarm system with magnets on it. You need a code and a key to open it.
The main alarm system was linked to magnetic contact on either side of the vault door. If opened, the magnets separated, triggering the alarm. The thieves founded an ingenious simple way round it. Before opening the vault, they removed both contacts, keeping them together, so the circuit wasn't broken, even when the door was opened. But then they had to defeat the lock with around a million of possible combinations. But no signs that the locks have been attempted* with. Detectors were at lost to see how the thieves could open it.
