eufy Security Indoor Cam S350 Dual Cameras 4K UHD - Clear 360

In this review the eufy Security Indoor Cam S350 earns its place as a capable indoor monitor for people who want very detailed video and reliable tracking. The single biggest reason to buy is the dual-camera 4K plus 2K telephoto arrangement that delivers sharp images and an effective 8x hybrid zoom, making faces and small details easier to identify. Setup is straightforward, the app works smoothly on tablets, and the camera's pan and tilt remove most blind spots, which is the core selling point for families monitoring children or pet owners keeping an eye on pets.

Key Features

• Dual 4K and 2K cameras: Provides a wide-angle 4K view plus a telephoto 2K sensor so you get high-detail coverage across the room.
• 8x hybrid zoom: The paired lenses combine to offer extended zoom for reading small details or zooming in on a subject without losing clarity.
• 360 pan and tilt: Full rotational coverage eliminates most blind spots and lets the camera scan an entire room for continuous monitoring.
• Smart AI tracking: eufy's self-developed algorithm follows people and pets around the room for automated subject tracking during motion events.
• Strong low-light performance: An f/1.6 aperture sensor and two infrared LEDs enable clear night vision to roughly 32 ft for after-dark monitoring.
• Local and network storage: SD card slot and added RTSP support allow local NAS recording when firmware and app are updated.

Who It's For

The Indoor Cam S350 is best for homeowners and renters who need detailed indoor surveillance: parents who want a baby monitor with clear image detail, pet owners who want to track animal movement around the house, and anyone who values the combination of wide and telephoto coverage for identifying faces or small objects. The smooth iPad and tablet app performance noted by customers makes it suitable for users who monitor on larger screens.

It may not be the right choice for users who require HomeKit integration, as HomeKit is not supported, or for those who need compatibility with older HomeBase 2 systems; the S350 is intended for use with HomeBase 3 on current firmware. Also, an SD card is not included, so plan to buy storage separately if you want local recordings immediately.

Pros & Cons

Pros

• Excellent image clarity from the 4K sensor for identifying faces and details.
• AI-powered tracking and 360 pan/tilt deliver continuous subject follow and near-complete room coverage.
• Strong night vision lets you see clearly up to about 32 ft in low light.
• Added RTSP support and SD card slot provide flexible local recording options.

Cons

• No HomeKit support, which may deter users invested in that smart home ecosystem.
• Not compatible with HomeBase 2, requiring HomeBase 3 and specific firmware for full functionality.

Our Verdict

The Indoor Cam S350 is a strong choice for anyone who needs high-detail indoor monitoring and automated tracking without buying multiple cameras. Its dual-camera design, effective zoom, and 360 coverage offer tangible value for families and pet owners, though lack of HomeKit and HomeBase 2 compatibility are limitations to consider.
