eufyCam S3 Pro 4K 2-Cam Kit vs Eufy EufyCam 3 2-Pack

The eufyCam S3 Pro is the newer, better camera. It adds dual radar plus PIR detection, MaxColor Vision for low light, a 100dB siren, and AI face recognition, and it ships with the HomeBase S380 that holds 16GB and expands to 16TB. The eufyCam 3 is the older generation with the same 4K resolution, 8x zoom, IP67 rating, solar charging and 16GB local storage, but weaker motion detection and no radar. Owners of both praise the no-subscription local storage; reviewers say the S3 Pro cuts false alerts sharply. Buy the S3 Pro unless the older kit is all you need for basic 4K coverage.

• Choose the eufyCam S3 Pro if you want the sharpest low-light image, fewer false alerts from radar detection, a loud siren and face recognition, and you are fine mounting two cameras.
• Choose the eufyCam 3 if you want simple 4K outdoor coverage with solar charging and local storage and do not need radar detection or a siren.
