Who is this for? This model is particularly excellent if you are looking for a "premium" feel for a modern office or a luxury home project. It solves the common issue where fingerprint sensors struggle with very dry hands or older individuals whose prints have faded.
Unlike older 2D systems that could sometimes be fooled by a photo, the H20 typically uses 3D structured light or infrared sensors.
Day & Night: It can recognize your face in total darkness thanks to the infrared camera.
Speed: It typically unlocks in less than 0.5 seconds as you approach the door—perfect for when you're carrying groceries or gear.
Liveness Detection: It is designed to distinguish between a real person and a high-resolution printout or video of a face.
One of the best features of this model is the built-in LCD screen on the interior panel.
Electronic Peephole: When someone rings the integrated doorbell, the outside camera sends a live feed to the indoor screen. You can see exactly who is outside without having to look through a tiny glass hole.
Mobile Alerts: Most H20 models connect to your Wi-Fi (often via the Tuya or TTLock apps), sending a photo of the visitor to your phone so you can unlock the door remotely.
Because facial recognition and video screens use more power than a simple fingerprint scanner, this lock usually comes with a Large Capacity Rechargeable Lithium Battery (often around 4200mAh) rather than standard AA batteries.
Emergency Port: If the battery dies, there is a USB emergency port at the bottom of the exterior handle to jump-start the lock with a power bank.
Mechanical Key: There is still a hidden keyhole for a physical override.
