U-Lock is from the ground up to be right for every front door. It's powerful enough to remotely lock or unlock without the need of Wi-Fi hub and is simple enough to grant access or deny access to residents. Most importantly, all these wonderful features housed in a design by German sports car designer to ensure that it looks and feels like itβs part of your house. In addition, U-Lock is one of the few devices on the market with WiFi and Bluetooth built-in and offers up to one year of lock battery life (with just 4 AA batteries), thanks to SGUDA's professional R&D team in Taiwan. The advantage of built-in WiFi is that users don't have to pay extra for a WiFi hub, while greatly enhance the overall security.
