Reviewers highlight the G4’s local AI, with the indoor chime handling tasks like facial recognition and loitering detection for faster smart alerts and automations without relying heavily on cloud processing.
Reviews highlight mmWave presence sensing and on-device facial recognition that make alerts smarter, reduce false triggers, and enable useful automations like unlocking doors or turning on lights.
Across reviews the Nest Doorbell Battery’s on device AI reliably distinguishes people, packages, animals and vehicles to cut down random street motion clips, and this evaluation reinforces that these smart alerts work well out of the box on the free tier while more advanced Familiar Faces recognition and extra sound detection still sit behind paid Nest Aware subscriptions for buyers who want named visitor alerts and longer history.
On-device AI handles people, package, and face detection and can auto speak to visitors approaching parcels, adding proactive security without a subscription, and Delivery Guard-style alerts in this review show how it can flag parcel arrivals and lingering visitors before problems start.
Onboard AI goes beyond basic motion by classifying people, packages, and familiar faces, and recent testing notes that the system reliably tagged deliveries while avoiding false package alerts, with deterrent voice messages available when someone approaches parcels.
On device and cloud assisted AI can identify faces, packages, pets, and vehicles and now works with separate detection zones per camera, providing focused smart alerts and categorized event lists, though this review notes that package detection can still be hit or miss in practice and full AI features require a Cam Plus subscription.
Built-in AI on the doorbell analyzes body shape and facial patterns to focus alerts on people at the door, and reviewers say it can even generate thumbnail images of visitors’ faces and helps filter out obvious non-human motion like insects or pets, though it is not flawless and can still misclassify some motion in tricky scenarios.
AI powered detection supports people and package alerts and benefits from years of algorithm refinements, but it does not offer the broader pet and vehicle classification that Wyze includes.
On its own the C31 only offers basic person detection, but when linked to HomeBase 3 it gains BionicMind AI that can distinguish people, pets and vehicles, though there is still no dedicated package detection so deliveries are treated like general motion events.
AI features like person, vehicle, and package detection work and can correctly flag events, but their server-based processing introduces extra delay before alerts are delivered.
This doorbell offers no onboard AI features, lacking person, package, or vehicle recognition, and reviewers see this as a clear disadvantage versus competitors that now use smarter classification to reduce nuisance alerts and add richer notifications.
