Lenel NetBox Quatro Series 4 is a multi-door edge controller for the Lenel ecosystem — pairs with OnGuard ACS or S2 Security Suite for enterprise deployment.
Key differences from commercial controllers: (1) Cyber-hardened government grade — TLS 1.3 + FIDO2 + encrypted firmware update (vs commercial OK plaintext); (2) Offline-capable 1000+ event — maintains unlock capability via cached schedule + audit log even if server connection is lost; (3) Native Lenel + S2 unified platform — no middleware required; (4) Built-in tamper switch — alerts when controller casing is opened.
Use cases: government buildings (ministry HQ), military bases, embassies, critical oil & gas facilities, JCI hospitals. Deployment pattern: 1 Quatro controller per 4 local doors + central OnGuard server at HQ federated. An Ninh Số has Lenel certified deployment managers.
