Smart Lock U300 + Hub M3 + Doorbell G4

See, Speak, and Unlock—All in Sync: Experience total front door command. The G4 Video Doorbell streams crisp 2K video to your phone, while its on-device AI instantly recognizes familiar faces. The U300 lock lets you grant access with a fingerprint, your phone via Apple Home Key, or a PIN. The M3 Hub ensures these devices work together seamlessly for instant response. The Power of Local Control: The revolutionary M3 Hub is the brain of your system. It runs automations directly on the device ("edge computing"), not in the cloud. What this means for you: When the G4 doorbell recognizes a family member, it can instantly unlock the U300 door lock without any internet-related delay. It's faster, more reliable, and works even when your Wi-Fi is down. Unrivaled Privacy and No Monthly Fees: Your privacy is paramount. The G4 Doorbell's facial recognition and video recording, along with the M3 Hub's automation processing, are all handled locally. Enjoy features like 7-day free secure cloud and local storage options without mandatory monthly subscriptions tying you down. Build Your Smart Home Universe: This kit is your foundation for a truly integrated smart home. The M3 Hub is a Matter Controller and Thread Border Router, bridging Zigbee, Wi-Fi, and IR devices. This means you can create powerful automations that extend beyond your front door—unlock the door to trigger lights throughout the house, adjust the thermostat, and open the blinds for the ultimate "welcome home" scene. Designed for a Modern Home: With its sleek, minimalist design, the U300 lock complements any decor. The combination of easy, keyless entry and powerful, behind-the-scenes automation from the M3 and G4 delivers a sophisticated and effortless living experience that feels like the future.
