Overview
The eufy Video Doorbell S4 (Wired) is Anker's 2026 flagship doorbell and the first to market with a 180° x 180° panoramic 'VR Mode'. A single 3K 9MP square sensor (3072x3072) captures head-to-toe and wall-to-wall coverage, while eufy's OmniTrack AI tracks and auto-frames people and packages anywhere in that frame. It records 24/7 to 8GB of built-in local storage with no subscription, adds dual spotlights for full-colour night vision, and is IP65 rated for outdoor use.
