ULTRALOQ Bolt NFC WiFi Smart Lock
This smart lock is designed for users who prefer smartphone-based access over biometric authentication. Combined with built-in Wi-Fi, homeowners can remotely control the lock, receive live notifications, and monitor activity through the U-home app without requiring a separate hub.
Another major advantage is Apple HomeKit compatibility, making it an appealing choice for users invested in Apple's smart home ecosystem.
ULTRALOQ U-Bolt Pro WiFi Smart Lock
The U-Bolt Pro WiFi Smart Lock remains one of ULTRALOQ's most versatile smart locks thanks to its biometric fingerprint reader and comprehensive keyless entry system.
Its fast 360-degree fingerprint scanner recognises registered users in a fraction of a second while storing up to 100 fingerprints, making it ideal for larger households.
Similar to the Bolt NFC model, the U-Bolt Pro also includes an integrated door sensor, IP65 weather protection, and Grade 1 security certification.
However, its biometric unlocking system makes it especially attractive for users who prioritise quick, touch-based access without relying on a smartphone.
Which smart lock should you prefer?
Both smart locks offer premium security, built-in Wi-Fi connectivity, and reliable remote management, but suit different needs.
The ULTRALOQ Bolt NFC WiFi Smart Lock is the better option for Apple HomeKit users and homeowners who prefer NFC tap-to-unlock with their smartphone or smartwatch.
On the other hand, the ULTRALOQ U-Bolt Pro WiFi is designed for users who value biometric fingerprint access, larger user capacity, and a more traditional smart lock experience.
