Transforming Access Control Operations TCP/IP Access Control Panel

Enterprise-Class Features Without Complexity

The C3‑400 eliminates the need for bulky server-based systems by embedding access logic directly into the controller firmware. This significantly reduces setup overhead, while enabling features like timed unlocks, interlocking doors, and alarm integration.

Flexible Reader Integration

Install any Wiegand standard reader—card, biometric, or mobile QR readers—all interoperable with C3‑400. It offers complete flexibility to future-proof your access system as needs evolve.

Intelligent Security Logic

Enable anti-passback, force first-card unlocking, multi-card entry sequences, or duress password setups—all configurable directly in the controller settings, thereby boosting security without external hardware.

Reliable Network Operation

If the network drops, the controller continues to operate using stored configurations and transactions. Events are captured locally and synced once connectivity is restored, ensuring uninterrupted access control.

Expandibility & Remote Management

Expandable via RS‑485-linked I/O expander boards, the system can scale to support up to 64 readers or devices. Ecosystem integration is supported via free SDK, allowing seamless communication with elevators, CCTV, or HR/ERP systems.

Perfect for Multiple Sectors in Kenya

The C3‑400 Access Control Panel Kit adapts well to:

• Corporate buildings: Manage access to multiple zones and departments.

• Educational campuses: Control gates, labs, dormitories, and administrative blocks.

• Government and public facilities: Enforce stringent entry protocols with audit-ready logs.

• Healthcare centers: Protect restricted zones like pharmacies or records rooms.
