Intelligent Door Lock for Heavy-duty Keyless Entry and Fingerprint Access

The Harfo door lock delivers security and convenience with its reliable and advanced technology. After research and development, the company has developed a new series of fingerprint locks to meet the diverse needs of customers. Harfo is committed to creating high-quality, high-performance door locks.

One of the key features of the Harfo door lock is the "One Touch to Unlock" function. Your phone serves as the key, and the full app control is both convenient and secure. You can check your digital lock data anytime, anywhere.

The lock also features an "Anti-Peep Password" function, which provides privacy when necessary. You can add random digits before or after the real passcode to open the door, ensuring that your actual passcode remains private.

Installation of the Harfo door lock is straightforward, requiring no locksmith or extra drills. You can easily install it with a Phillips screwdriver in just a few minutes. The "Auto Lock" function ensures that you never have to worry about forgetting to lock your door, as it will automatically lock behind you.

The lock is powered by a Micro USB power bank, which can serve as a temporary power supply. The lock can accommodate up to 300 users, making it suitable for homes, offices, apartments, schools, and libraries.

The Harfo door lock offers additional security features, including a "Private Lock" mode. In this mode, only the admin user can access the door, while other users cannot open it, providing a secure and private personal space.

The keyless lock is designed to fit most standard US doors, with a door thickness range of 1 3/8 inch to 2 3/16 inch (35mm-55mm). The lock has a low energy usage, with the battery lasting up to 9 months to 1 year under normal use. Rechargeable batteries are not recommended, as their voltage is typically lower than the required 1.5V.

In summary, the Harfo door lock delivers a comprehensive range of features, including fingerprint, passcode, IC card, app control, and physical keys for unlocking. It also offers remote control and Wi-Fi access, easy installation, and various security functions, making it a versatile and reliable choice for securing your home or office.
