Key features:

Security and Access Dual-Credential Access: Supports multiple methods of entry, typically:

Card Only (Mifare 13.56 MHz proximity fobs/cards).

PIN Only (4-digit PIN code).

Card + PIN (for enhanced security).

Mifare Technology: Utilizes the higher-frequency 13.56 MHz standard, providing more secure encryption than the older 125 KHz EM/ID cards (though some versions may be dual-frequency compatible).

User Capacity: Can typically store 8,000 users (cards/PINs), depending on the exact variant.

Tamper Alarm: Includes functionality to trigger an alarm if the unit is forcefully removed from its mounting location.

Design and Durability Outdoor/Waterproof: Designed for external use, featuring a robust metal (often aluminum alloy) casing and an integrated keypad.

Environmental Rating: Typically holds a high Ingress Protection rating (e.g., IP65 or IP66), protecting it from dust and strong jets of water.

Backlit Keypad: The keypad is illuminated for easy operation in low-light conditions.

System Integration Standalone Operation: It functions as a complete access controller in a single unit, managing the door lock directly without needing an external control panel.

Wiegand Interface: Features a Wiegand 26/34 output/input interface, allowing it to be connected to an external access control panel if required, effectively allowing it to act as a simple card reader within a larger system.

Lock and Alarm Control: Provides a built-in relay (e.g., 12V DC / 2A) to connect directly to an electric lock, strike, or magnetic lock, as well as an interface for connecting an external alarm system.

Power: Requires standard DC 12V power supply.
