· DTMF Settings: Can modify the DTMF unlocking codes of the main/auxiliary doors (supporting 0-9, *, #) to ensure unlocking safety (the main and auxiliary door codes cannot be the same);

· Dial Settings: Can enable/disable the automatic dialing function, set the number of automatic dialing digits (1-6 digits, default 4 digits). After enabling automatic dialing, visitors only need to enter the set number of digits of the room number to call automatically without pressing the "Call" key. If the number of digits is insufficient, they still need to press the "Call" key to confirm, improving access efficiency;

· Correlation Settings: Can set the trigger conditions (postal lock/fire alarm/universal input/main door unlocking/auxiliary door unlocking), output actions (On/Off), and duration (0-255 seconds, default 30 seconds) of universal output 3/4. For example, set "Fire alarm triggers universal output 4 (alarm light) to turn on for 30 seconds" to improve emergency response capabilities;

· Engineering Testing: Supports functions such as audio testing, video testing, display screen testing, voice testing, system restart, and factory reset, facilitating installation, commissioning, and troubleshooting by engineering personnel.

VII. Convenient Installation and Humanized Design: Reducing the Threshold of Use, Adapting to All Scenarios

In terms of installation and design, the product fully considers practicality and convenience, reducing installation costs and the threshold of use, and adapting to different installation environments.

1. Simple Installation Steps, Completed in 10 Minutes

The product installation does not require complex processes, and can be quickly completed by property or engineering personnel:

· Step 1: Take out the waterproof sponge sticker included in the package;

· Step 2: Mark the height on the installation wall (4250px from the ground), ensure the device is vertical and horizontal, drill holes at the marked positions with tools, and insert plastic columns;

· Step 3: Remove the device's rainproof cover, align the mounting holes with the plastic columns, install the fastening screws to fix the device, and then reinstall the rainproof cover to complete the installation.

The overall design of the device is compact, and the mounting holes are accurately matched with the waterproof sponge, which effectively prevents rainwater from seeping in and ensures safe outdoor use; the installation height of 4250px conforms to ergonomics, facilitating the elderly and children to operate the keyboard.

2. Humanized Detail Design, More Comfortable to Use

The product fully considers the user experience in details, making it more convenient and safe to use:

· Simple Operation Interface: The main interface clearly displays core functions (enter room number to call, view resident list, password unlock, settings), with large and clear buttons and clear labels, which can be easily operated by the elderly and children;

· Waterproof and Dustproof Design: The body is equipped with a rainproof cover and a waterproof sponge sticker, with excellent protection performance, and can adapt to harsh outdoor environments;

· Low Power Consumption Design: Static working current ≤ 0.25mA (DC 12V), working current ≤ 700mA (DC 12V), energy-saving and environmentally friendly, reducing use costs;

· Clear Fault Prompt: When there are situations such as no SIM card inserted, no telephone line connected, network abnormality, or wrong password, the system will give clear icon or text prompts, facilitating quick troubleshooting.

VIII. Intelligent Platform Linkage: Remote Management, Data Synchronization

To improve management efficiency, the product is equipped with an intelligent access control management platform, supporting real-time data synchronization between the device terminal and the computer terminal. The property or enterprise can achieve remote management through the platform without on-site operation, making management more efficient.

1. Core Functions of the Platform

The intelligent access control management platform provides rich management functions, covering core needs such as device management, user management, and record query:
