Your fingerprint is one of a kind, so let its uniqueness work for you. The Biometric Wall Vault mounts in your home and allows access by reading your fingerprint. This wall safe is made of stainless steel and will mount into any wall of your home between two 16-inch on-center studs. Unlike most electronic wall vaults, the Keypad Wall Vault runs on a rechargeable battery, so no wiring is required. Up to five users can be added to the system. Approved by the Department of Justice as a firearm safety device, the Biometric Wall Vault can be used to keep the family protection out of the hands of children. A hidden second compartment can store documents, passports, and other valuables. In addition to gaining entry with your fingerprint, access can also be granted through a user-programmable five-digit pass code. For strictly keypad access, install a Keypad Wall Vault, which allows you to set a one- to eight-digit security code. In addition to running on the included 12-volt rechargeable battery, the Biometric Wall Vault can operate on 12V DC wiring; please consult an electrician for wiring in.
