TCP/IP Access Control Panel Board DC12V 1–4 Door Entry System
TCP/IP Access Control Panel Board DC12V 1–4 Door Entry System
TCP/IP Access Control Panel Board with DC12V 5A Metal Power Supply Box — 1, 2, or 4 Door Entry System
Take full command of your office or building's entry points with this professional-grade TCP/IP Access Control Panel Board. Housed in a durable metal enclosure with an integrated DC12V 5A power supply converter, this all-in-one controller supports up to 4 doors, 20,000 users, and 100,000 offline event buffers — making it ideal for small offices, multi-floor facilities, warehouses, and commercial spaces. Made in Mainland China.
Key Features
- Flexible Door Control: Manage 1, 2, or 4 access points from a single controller. Configure doors for card-in/button-out or card-in/card-out operation.
- TCP/IP Connectivity: Network-based communication for seamless integration with your existing IT infrastructure. Supports unlimited controllers (up to 256 ports per hub).
- High Capacity: Handles up to 20,000 enrolled users and stores 100,000 offline event logs for reliable audit trails even during network downtime.
- Universal Reader Compatibility: Wiegand 26-bit input supports all major card technologies — HID, EM, Mifare (M1), and more. Reader-to-controller distance up to 100 m.
- Robust Metal Enclosure: PCB board protected in a sturdy metal box with a built-in DC12V 5A power supply converter — no separate power unit needed.
- Advanced Access Modes: First Card Unlock, Multi-Card Door Open, Anti-Passback, Anti-Tailgate, Emergency Lock, Electronic Card, and time-based unlock schedules.
- Alarm Integrations: Built-in alerts for prolonged door-open, unauthorized entry, and duress situations. Fire & alarm linkage support via expansion card.
- Software Compatibility: Works with Access and SQL databases. Adjustable door-open time from 1 to 600 seconds.
- Fail-Safe Security Mode: Ensures doors default to a safe state in the event of power interruption.

Frequently Asked Questions
Q: Can this TCP/IP access control panel manage all four doors independently?
A: Yes. The LK0023 access control board supports independent management of up to 4 doors simultaneously. Each door can be configured with its own schedule, access rules, card reader, and time-based unlock settings — all managed from a central software interface using Access or SQL databases.
Q: What card reader types are compatible with the Wiegand 26-bit input?
A: The panel is compatible with any card reader that uses the Wiegand 26-bit protocol, including popular technologies such as HID, EM, and Mifare M1 (contactless smart cards). The maximum cable distance from reader to controller is 100 meters (default recommended distance is 80 meters).
Q: Does the system work if the network connection is lost?
A: Yes. The controller stores up to 100,000 offline event buffers locally, so access events continue to be logged even during network downtime. Once connectivity is restored, all offline logs sync back to the management software automatically.
Q: How many users can be enrolled in this access control system?
A: The LK0023 supports up to 20,000 enrolled users, making it well-suited for medium-to-large offices, multi-tenant buildings, and commercial facilities.
Q: Is a separate power supply required for this access control box?
A: No. The metal enclosure includes a built-in DC12V 5A power supply converter, so no additional external power supply unit is needed. Simply connect to your standard AC mains and the unit powers the control board and connected door hardware.
