A bank vault is a secure room or space within a bank designed to protect valuable items, such as cash, documents, and jewelry. These vaults are built with strong materials, like steel and reinforced concrete, to prevent unauthorized access and theft. They often feature advanced locking mechanisms and security systems, including alarms and surveillance cameras. Bank vaults are essential for maintaining the safety of a bank's assets and ensuring customer trust. In addition to physical security, some banks offer safety deposit boxes within their vaults, allowing customers to store personal valuables securely.
