The ULTRALOQ Bolt Fingerprint WiFi Smart Deadbolt is a Matter-over-Thread smart lock featuring 8-in-1 keyless entry and robust ANSI Grade 1 security.

The eufy Security Video Smart Lock S330 is a 3-in-1 device combining a fingerprint deadbolt, 2K HD camera, and video doorbell with chime. It offers keyless entry via app, voice, keypad, or keys, powered by a single 10,000 mAh battery that lasts up to 365 days without requiring subscription fees. The heavy weight and setup complexity are the main drawbacks, but it is ideal for users wanting comprehensive front-door monitoring.
