South Korean tech start-up FiveGT said Wednesday it has installed its face-recognition door lock, called Ufacekey, at a residential building in Gugi-dong, northern Seoul.

Ufacekey includes a face-recognition robot that detects tens of thousands of face characteristics of a user. It takes less than one second to process the recognition. With an infrared camera embedded, the robot also recognizes faces in the dark.

The system is compatible with smartphones so that users can monitor family members, especially young children, returning home. They can open the door using their smartphones.

When a stranger tries to gain access, the system takes and stores the person’s photo to prevent crimes.

The company also added some emotional features by allowing users to register their own voice or text messages to appear when family members enter home.

“Ufacekey is the most convenient and safest security system. We aim to lead the market,” said FiveGT CEO Jeong Gyu-taek.
