Full specifications and feature overview for the Ultraloq U-Bolt Pro Bluetooth-enabled fingerprint and keypad smart deadbolt.
Product overview and specifications for the Ultraloq U-Bolt Pro — a Bluetooth-enabled fingerprint and keypad smart deadbolt with six ways to unlock, from U-tec.
U-Bolt Pro is designed as a secure and versatile deadbolt, offering six ways to unlock with or without a smartphone: Smartphone App, Fingerprint, Passcode, Proximity Unlock, Magic Shake, and Mechanical Key. With the optional Bridge WiFi adaptor, users can control door access remotely and monitor activity while away from home.
The Bridge WiFi Adaptor lets you open the U-Bolt Pro anytime, from anywhere. It instantly lets friends and guests into your home remotely, shares temporary access to guests, and sends instant alerts every time someone unlocks the door. You can view users and logs no matter where you are. The Bridge uses Wi-Fi to connect to your home network and Bluetooth to connect to the smart lock. Works with the U-tec App for iOS and Android, and with Alexa, Google Assistant, and IFTTT. There is no monthly service fee.
