ZKTeco C3-100 Plus 1-Door Access Control Panel — Multi-Door Access Control Panel

Why integrators specify the C3-100 Plus 1-Door Access Control Panel

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

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

📡 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.

🛡️ 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.

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

Frequently asked questions

Q. How many doors can the C3-100 Plus 1-Door Access Control Panel control?
Door capacity depends on the variant — please refer to the model designation. Larger panels in the ZKTeco controller range support multiple doors with reader pairs on each.

Q. Does it support OSDP readers?
Yes. The C3-100 Plus 1-Door Access Control Panel accepts both OSDP and standard Wiegand reader inputs. Therefore, integrators can mix legacy Wiegand readers with modern OSDP readers on the same panel.

Q. What software does it work with?
The C3-100 Plus 1-Door Access Control Panel integrates natively with ZKBio CVSecurity and ZKBio Access, plus BioTime for attendance-focused deployments. Additionally, an open SDK is available for custom HRMS integrations.

Q. What happens if the network goes down?
Door rules and the recent event log are stored on the controller itself. Consequently, doors keep operating to policy even when the management server is unreachable, and events sync back the moment connectivity returns.
