ZKTeco C3-400 Plus 4-Door Access Control Panel

ZKTeco C3-400 Plus 4-Door Access Control Panel — Multi-Door Access Control Panel

The ZKTeco C3-400 Plus 4-Door Access Control Panel sits at the heart of any serious ZKTeco access-control deployment. Furthermore, it integrates natively with ZKBio CVSecurity, ZKBio Access and BioTime — so user enrolment, door rules and audit logs all live in one consistent place.

Why integrators specify the C3-400 Plus 4-Door Access Control Panel

🛡️ On-board event log — events are stored even when the management server is unreachable. Consequently, audit trails stay complete.

📡 OSDP + Wiegand — modern OSDP for new readers, plus Wiegand for retrofits. As a result, integrators don't have to pick one and lose the other.

🔌 Multi-door support — drive multiple doors from one panel. Therefore, wiring costs and rack space drop noticeably on larger sites.

📊 Thousands of users — on-board capacity scales for enterprise deployments without external database tricks.

🔋 Optional UPS backup — keeps doors operating through short power outages, so security policy stays enforced when the lights go out.

🛠️ DIN-rail or wall mount — installers can put it where it actually fits the cabinet, not where the panel dictates.
