Performance

The Eufy Security Indoor Cam S350 shines in its overall performance, balancing clarity, tracking accuracy, and ease of use.

Setup and Installation

Setting up the S350 is straightforward. Users simply plug in the camera, download the Eufy Security app, and follow the on-screen prompts. The camera connects to both 2.4 GHz and 5 GHz Wi-Fi networks, which is a welcome improvement for homes with dual-band routers. Pairing with HomeBase 3 is seamless for those who already own Eufy’s ecosystem.

Video Quality

One of the most significant selling points of the S350 is its video clarity. The 4K wide-angle camera delivers incredibly sharp footage, while the 2K telephoto lens excels at zooming in on subjects. Even at the maximum 8× zoom, details remain discernible, making it easy to identify faces, pet behavior, or small objects.

Daytime footage appears bright and vivid, with excellent color reproduction. At night, the infrared night vision kicks in, and thanks to its large aperture and powerful IR LEDs, the footage remains clear without overexposure.

Motion Detection and Tracking

The AI-powered motion tracking is one of the S350’s highlights. Once motion is detected, the camera smoothly pans and tilts to follow the subject. This feature is particularly useful for pet owners, as the camera can follow cats or dogs across the room.

The human and pet detection feature effectively reduces false alerts from non-essential motion, such as shadows or moving curtains. However, in fast-paced scenarios, there may be occasional lag in tracking, especially if multiple subjects are in the frame.

Connectivity and App Experience

The Eufy Security app remains intuitive and user-friendly. Live streaming, recorded video playback, and adjusting camera settings are all accessible within a few taps. Notifications are quick to arrive, though a few users report inconsistent delays during high network congestion.

The app also allows two-way audio communication, making it an effective baby monitor or pet camera. The sound quality is serviceable, though it could benefit from a bit more clarity on the receiving end.

Storage Options

The S350 supports local storage via microSD cards and RTSP for NAS storage. This flexibility allows users to avoid monthly cloud storage fees, a major plus compared to competing brands. Cloud storage is optional for those who prefer it.

Customer Feedback

Customer reviews paint a largely positive picture of the Eufy Security Indoor Cam S350.

Positive Feedback

• Picture Quality: Customers consistently praise the crystal-clear 4K video quality. Many users highlight how well the camera performs during both day and night.
• Ease of Use: The straightforward setup process and intuitive app make the camera accessible, even for those who are not tech-savvy.

Constructive Criticism

• Limited Ecosystem Support: Lack of HomeKit compatibility and the requirement for HomeBase 3 (if integrating with Eufy’s broader ecosystem) has frustrated some users.

Pros and Cons

To summarize the camera’s strengths and weaknesses, here is a clear breakdown:

Pros	Cons
Exceptional 4K UHD video quality with hybrid zoom	Occasional lag in live feed and notifications
Full 360° pan and tilt coverage	Requires HomeBase 3 for full ecosystem integration
AI-powered motion tracking for humans and pets	No Apple HomeKit support
