Triple-Lens Bullet-PTZ Camera in 4K Max View: The upper 4K wide-angle lens delivers a 122° fixed view of the area, while the lower 2K Pan-Tilt-Zoom lenses feature 8× auto-zoom and 360° pan for complete coverage. Note: To ensure seamless security, update your eufy app to version 5.0.71 or above. Dynamic Tracking and Auto-Framing: When the bullet cam detects a subject, the Pan-Tilt-Zoom cam locks on and auto-tracks them with sharp, centred close-ups from up to 50 metres away. Auto-zoom keeps them framed until they exit view for a clear picture the whole time. Live Cross-Cam Tracking: All your cameras work in sync to track movement in real-time. When one camera reaches its limit, another takes over instantly, ensuring continuous, uninterrupted coverage around your home. AI-Powered Video Finder: Instantly find what you're looking for by searching with keywords on the eufy app to avoid scrolling through hours of footage.
