About this subject

The door of a modern bank vault represents the pinnacle of physical security in the financial sector. In Brazil, bank vaults adhere to strict standards from the Central Bank and the Brazilian Association of Technical Standards (ABNT), such as NBR 15000, which specifies requirements for modular vaults. These doors are made of high-strength steel, reinforced concrete, and multiple locking systems, weighing up to 10 tons. The closing mechanism includes bolts and screws that fit into reinforced frames, along with intrusion sensors and integrated cameras. Technological advancements have brought biometric locks and timers that prevent opening during unscheduled hours. Historically, vault security evolved from mechanical models in the 19th century to current digital systems, highlighting innovations like fire and explosion-proof vaults. In 2022, Brazil recorded over 1,500 ATM burglaries, underscoring the importance of robust central vaults. Interestingly, the world's largest vault door is at the Federal Reserve Bank of New York, weighing 90 tons. Periodic maintenance of these doors is crucial, involving gear lubrication and alarm testing, ensuring access is restricted to authorized personnel only.
