P2
Product 2: Schlage Encode Plus Smart Lock
3.2
The lock includes an alarm/siren, but loudness evidence is mixed to weak because multiple reviewers say it is not very loud.
App
P1
Product 1: eufy Video Smart Lock S330
4.3
The app was generally praised as smooth, clean, user-friendly, and feature-rich, with live video, settings, and remote controls accessible from the phone.
P2
Product 2: Schlage Encode Plus Smart Lock
