The camera can be controlled manually through the app, or you can enable automatic tracking to follow moving objects.
AI Tracking and Object Detection
Advanced AI tracking is a standout feature of the Eufy Indoor Cam S350. The camera can distinguish between humans, pets, and other objects, reducing false alerts and ensuring you only receive relevant notifications. This precision is particularly useful for those who want to monitor pets or children.

Eufy offers flexible storage options with the S350. You can choose between local storage via a microSD card (up to 128GB) or cloud storage through the Eufy Cloud service, which starts at $2.99 per month for 30 days of video history.
