Why integrators specify the C3-400 Plus Package B Access Control Panel

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

🧠 Native integration — works directly with ZKBio CVSecurity, ZKBio Access and BioTime — no middleware required.

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

🔔 I/O for alarms & locks — wire in door sensors, exit buttons, alarm horns and electric strikes without extra adapters.

🔌 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.
