Eufy Security S380 EufyCam 3 outperforms on resolution and privacy with 4K local AI and up to 16TB storage per RTINGS and Wirecutter comparisons, while Wyze Cam v4 trails at 2K but costs far less upfront. Eufy avoids subscriptions entirely unlike Wyze's feature-limited free tier noted in CNET reviews. The gap favors Eufy for users prioritizing data control over initial savings.
