FAQ
What makes the video quality of the eufy Video Doorbell S4 different from other doorbells?
Video Doorbell S4 features 3K resolution (3072 × 3072) with a 180° horizontal and vertical field of view, for a full head-to-toe view with no blind spots. It also delivers 24 FPS video, 8× zoom, and HDR for clear and detailed footage, day or night.
What is a VR doorbell?
A VR doorbell offers an immersive viewing experience by turning your doorbell video into a virtual front door. With a full-screen, borderless view and intuitive gesture controls, it provides a more natural way to monitor your doorstep.
What are the benefits of OmniTrack™?
OmniTrack™ is eufy’s AI-powered auto-tracking and auto-framing technology. It automatically keeps moving people centred in the frame, helping ensure important moments are clearly captured without manual adjustments.
What power supply does the Video Doorbell S4 use?
It connects exclusively to an existing 16–24 VAC (10 VA or above) doorbell wiring system. S4 is a wired-only model and does not support battery-powered use or solar power. A small built-in battery provides emergency backup during power cuts.
Is the Video Doorbell S4 compatible with my smart home ecosystem?
It works with eufy HomeBase S380, mini, Pro S1, MindBase, NVR, and Smart Display E10, and supports the Chime when connected to HomeBase 2. It works with Alexa and Google Assistant, and Apple HomeKit when connected to HomeBase S380 or MindBase.
Will my internet connection support 3K streaming?
An upload speed of at least 8 Mbps is recommended, with 12 Mbps or higher for the best experience. A stable Wi‑Fi connection or a mesh Wi‑Fi system can help ensure smoother streaming.
