Eufy Indoor Cam S350 Review: Two Lenses, 4K and 8x Zoom on a 360° Pan-Tilt Head
The Eufy Indoor Cam S350 is a plug-in indoor camera that pairs a 4K wide-angle lens with a 2K telephoto lens on a pan-tilt head, so it can show the whole room and a zoomed-in close-up at the same time. It records 24/7 to a microSD card or a HomeBase 3 without a monthly fee, tracks people and pets, and listens for a crying baby. The trade-offs are infrared-only night vision, no Apple Home or Matter, and only partial Google support, which makes it a mid-range pick for Alexa and Home Assistant homes that want detail rather than ecosystem breadth.

Who is the Eufy Indoor Cam S350 for?
It suits anyone watching a big indoor space: an open-plan living room, a nursery or the corner where the dog sleeps. The 360° pan and 75° tilt cover the room, AI tracking follows people and pets, and crying detection makes it a natural baby monitor. It is strictly an indoor camera powered from a USB-C adapter, with no battery and no weather rating, so it belongs on a shelf, a wall or a ceiling inside.
What the Eufy Indoor Cam S350 offers
The headline feature is the dual-lens design. A 4K wide-angle lens with a 130° diagonal view keeps the whole scene, while a 2K telephoto lens with a 46° view zooms in, for 3x optical and 8x hybrid zoom, and the app can show both views on one screen. The camera pans to preset spots and patrols them on a schedule, detects motion, people, pets, sound and crying, and supports two-way talk, activity zones, privacy zones and a built-in alarm. Recordings go to a microSD card of up to 128GB or to a HomeBase 3, including 24/7 recording, and an RTSP stream lets an NVR or NAS record it too. Dual-band Wi-Fi 6 works on 2.4 GHz or 5 GHz networks.
What to know before you buy
Night vision is infrared only: two IR LEDs light a person up to 40 feet away, but there is no spotlight and no color night vision. eufy states the camera does not support HomeKit, so there is no Apple Home and no HomeKit Secure Video, and it is not Matter certified. Google Assistant can show the live view on a smart display, yet eufy says Google Home itself is not supported. Detection covers people, pets and sounds, not vehicles, packages or familiar faces. The microSD card is not in the box, and cloud backup needs a subscription. Home Assistant reaches it through the community eufy-security integration rather than an official one.
Is the Eufy Indoor Cam S350 worth it?
For an indoor camera, the combination of a 4K wide view, a real telephoto lens, full pan-tilt coverage and free local 24/7 recording is uncommon, and it is what you pay the mid-range price for. If you live in Alexa or Home Assistant and want to read details across a large room, it is a strong choice. If your home runs on Apple Home, Google Home or Matter, or you need color night vision, a simpler single-lens camera with those integrations is the better fit.
