Product Introduction

The QA40 facial recognition smart lock is an advanced security solution that combines cutting-edge technology with convenience and peace of mind.

The QA40 facial recognition smart lock utilizes advanced 3D structured light facial recognition technology, powered by 3D structured light and AI algorithms. Users can quickly unlock the door by scanning their face, opening it without a key, freeing their hands and eliminating the worry of lost keys. A wide-angle peephole camera provides 24/7 access control, providing around-the-clock security and worry-free travel.

The QA40 smart lock features a built-in wide-angle peephole camera for clear and comprehensive monitoring of the surrounding environment. The peephole camera also features active monitoring, capturing images of suspicious individuals lingering at the door. The door features a large 3.5-inch HD screen with high color reproduction, allowing elderly and children at home to clearly identify visitors at a glance.

The mobile phone remote unlocking function provides convenient and reliable access control. When a visitor rings the doorbell, the peephole camera captures a photo of the visitor and sends it to the user's smartphone for identity verification. The user can then remotely unlock the door, ensuring safe and efficient entry and exit.

The QA40 facial recognition smart lock features an anti-theft alarm. If a tampering attempt occurs, the lock emits a warning sound and sends a notification to the user, providing enhanced security.

The smart lock also features a low-battery reminder. When the battery is low, both the lock and the phone will proactively remind the user to replace the battery, preventing the lock from being locked.

In addition to facial recognition, the QA40 smart lock also offers fingerprint unlocking. Using a semiconductor fingerprint module, the lock accurately and sensitively recognizes fingerprints, enhancing security and providing a fast, seamless unlocking experience.

The QA40 facial recognition smart lock is a comprehensive security solution that prioritizes user convenience, security, and innovation. Experience the future of smart home technology with the QA40 smart lock, offering advanced security features and peace of mind for homeowners.
