K4

The KRYPTO K4 is a mullion-style Bluetooth reader and keypad, which when combined with CDVI’s EV2 credentials, offers a user friendly high-security solution. Utilizing the secure protocol of CDVI, the encryption keys guarantee end-to-end encryption between the credential, the reader and the A22K controller.
The K4 is compatible with the ATRIUM BT mobile app and the KRYPTO Mobile-PASS, allowing users to unlock doors with their smartphones.
