ZKTeco (C3-400 PACKAGE B) C3 Access Control Panels

The ZKTeco C3-400 Package B is a professional, IP-based 4-door access control solution designed to provide advanced, centralized security management for commercial offices, data centers, factories, and multi-tenant buildings. As a comprehensive “Package B” bundle, this kit moves beyond a standalone circuit board, arriving as a fully integrated field installation unit housed within a heavy-duty, powder-coated metal enclosure. The system includes a dedicated 12V 3A linear power supply with integrated battery backup charging circuitry to keep physical access points operational during building blackouts. Capable of managing up to 4 independent doors on a single controller, the C3-400 features a powerful 32-bit internal processor that locally stores thousands of cardholder credentials and historical events, ensuring full access privileges are enforced even if network communication to the central management server is completely interrupted.

Key Features

• Complete Package B Infrastructure: Arrives fully assembled inside a rugged, wall-mountable steel cabinet equipped with a 12V 3A power supply, a lock with two keys, and an inline diode to protect the board from electric lock voltage spikes.
