ZKTeco C3-400 Plus 4-Door IP-Based Access Control Panel

Establish high-speed, enterprise-grade card access security across your entire facility footprint. The ZKTeco C3-400 Plus 4-Door IP-Based Access Control Panel is a high-density, network-centralized controller engineered to manage up to four distinct entry points with absolute structural stability. Operating over a native TCP/IP pipeline, this pro-tier controller board shifts access logic away from vulnerable doorway points and into the absolute safety of your network server room or IT closet.

Built explicitly for high-throughput commercial tracking, the C3-400 Plus natively supports up to four standard 26-bit Wiegand proximity readers—giving you full authority to deploy RFID cards, high-security smart cards, key fobs, or entry PIN pads. Backed by an advanced embedded firmware engine, it processes complex interlocking rules and access permissions locally on the edge, ensuring your facilities remain uncompromised even during a total network blackout.

Why Security Integrators & IT Directors Standardize on the C3-400 Plus

• Centralized 4-Door Network Hub: Commands up to 4 doors from a single standalone enclosure. Manage full bidirectional tracking by running 4 entry readers alongside exit push-buttons, or establish strict entry-only rules across 4 separate perimeter points.
• Massive 30,000 Cardholder Database: Packed with heavy-duty internal flash memory. It smoothly stores 30,000 distinct card templates and holds a massive local buffer of 100,000 event logs, preventing any loss of critical audit trails.
• Airtight Interlocking & Mantraps: Program advanced industrial security parameters natively. Easily create tight multi-door interlocking paths for banks or laboratories, ensuring outer doors lock down completely before inner high-security bays can be opened.
• Smart Global Anti-Passback Guards: Stop credential sharing and tailgating fraud instantly. The panel executes strict anti-passback rules, requiring users to properly badge out before their card or fob will grant entry into the zone again.
• Multi-Point Output Relay Automation: Loaded with 4 primary Form-C lock control relays, alongside 4 dedicated auxiliary output relays. Use them to automatically sound a horn, flash a strobe light, or signal an emergency monitoring station during a breach.
• Auxiliary Input Sensor Links: Outfitted with 4 auxiliary input terminals to integrate building smoke detectors, window glass-break sensors, or passive infrared motion trackers straight into your facility's master lockdown loop.

Enterprise-Grade Proximity Access Applications

The ZKTeco C3-400 Plus is the definitive hardware backbone for scalable RFID-driven environments:

• Corporate High-Rises & Tech Hubs: Centralize access across entire floors, linking employee badges to primary entry gates, elevators, storage bays, and executive wings via a single software panel.
• Commercial Fulfillment Warehouses: Manage high-turnover logistics spaces where workers utilize standard proximity fobs or badges for rapid, hands-free tracking through heavy loading zones.
• Hospitals & Medical Centers: Secure sensitive medicine cabinets, staff-only wards, and patient file archives against public walk-throughs, while keeping a precise, digital chain-of-custody log.
• Multi-Tenant Apartment Complexes: Control vehicle gate barriers, main lobbies, gym doors, and parking garage perimeters out of a single, secure centralized network panel room.
