eufy Security HomeBase 3 (HomeBase S380)

Quick verdict

Based on published specs and editorial comparison, HomeBase 3 (S380) is the infrastructure piece, a hub offering local storage expandable up to 16TB and BionicMind AI facial recognition with advanced encryption. It is the keystone for eufy owners committing to a no-monthly-fee, local-first architecture rather than per-camera cloud terms. Buy it to centralize and future-proof a growing eufy camera fleet, not as a standalone capture device.
