Product Overview
This Standalone Access Controller integrates a video door phone interface, providing a complete entry control and communication solution for commercial and residential access points. Designed as a robust RFID and PIN code system, it offers secure, keyless entry for up to 1,000 users. As a dedicated do rfid reader manufacturer, we have engineered this unit for reliable daily operation in demanding environments, from office lobbies to industrial facility gates. System integrators and property managers choose this unit for its straightforward deployment, eliminating the need for complex host computer software for basic access control tasks.
Key Features & Advantages
This device provides dual-factor authentication by combining 125kHz EM card reading with a PIN code keypad, preventing unauthorized entry even if a card is lost. The unit features a solid ABS construction and a wide operating temperature range from -45℃ to 60℃, ensuring stable performance in both indoor and outdoor installations. The built-in relay, supporting a lock output of up to 3A, is compatible with most electric door strikes and magnetic locks. For project contractors requiring a cost-effective and dependable solution, this controller reduces installation complexity and long-term maintenance requirements.
- Dual Access Modes: Supports Card Only, PIN Only, or Card + PIN for flexible security level configuration.
- High User Capacity: Onboard memory stores up to 1,000 user credentials, sufficient for small to medium-sized facilities.
- Robust Relay Output: The 3A lock output relay directly drives standard maglocks or electric strikes without an additional power supply module.
- Video Door Phone Integration: Provides communication and remote unlock capability, enhancing visitor management and property control.
- Wide Temperature Tolerance: Operational from -45℃ to 60℃, built for extreme climates and unheated entryways.
- Short Circuit Protection: The output includes short circuit protection with a response time of ≤100μS to prevent equipment damage during installation faults.
