5. Operating Your System
5.1 Live View and Recording
The system provides 24/7 continuous recording to the NVR's local storage. You can access live views and recorded footage via the eufy Security app, web interface, or a connected display.
- App/Web Interface: Open the eufy Security app or log in to the web portal to view live feeds from all cameras. You can switch between individual camera views or a multi-camera grid.
- Local Display: Use the connected monitor/TV and USB mouse to navigate the NVR interface for live viewing, playback, and system settings.
- Recording Modes: The system supports 24/7 recording, motion-activated recording, and scheduled recording. These settings can be configured via the NVR interface or the eufy Security app.
5.2 AI Features and Tracking
The Bullet-PTZ cameras offer advanced AI capabilities for enhanced surveillance.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your eufy security system.
- Clean Lenses: Periodically clean camera lenses with a soft, dry cloth to remove dust, dirt, or smudges that may affect image quality.
