4.1 App Interface and Live View
The eufy Security app provides access to live view, recorded footage, and camera settings. From the app's home screen, you can view snapshots from your cameras and tap to access the live feed. The live view interface allows you to record, take screenshots, use two-way talk (half-duplex), listen in, and access playback.
4.2 Playback and Recording
The eufyCam E330 supports 24/7 continuous recording. In the playback section of the app, you will see a timeline of recorded footage. Yellow areas on the timeline indicate AI motion events, while blue areas represent continuous recordings. You can pinch to expand the timeline for detailed viewing.
4.3 Motion Detection and AI Features
The HomeBase 3 powers advanced AI features including Human Recognition, Human Detection, Vehicle Detection (Beta), and Pet Detection (Beta). You can customize activity zones to define specific areas for motion detection. The BionicMind AI self-learns and improves recognition accuracy over time.
4.4 Cross-Camera Tracking
This feature allows the HomeBase 3 to merge clips of the same person or event from multiple cameras, providing a seamless view of movement across your property. This helps in easily tracking movement within the app.
4.5 Night Vision and Spotlight
The cameras offer multiple night vision modes: B&W Night Vision (infrared), Color Night Vision (using the built-in spotlight), or you can turn off night vision entirely. The 100-lumen spotlight can be manually activated or set to turn on when motion is detected in dark conditions.

5. Installation Tips
The eufyCam E330 cameras are IP67 weather-resistant, making them suitable for outdoor installation. The cameras are plug-in powered, requiring a power outlet within 16.4 ft (5 m) or 33 ft (10 m) with the included extension cable.
For installation, loosen the screws on the mount arm to adjust the camera's position. Secure the camera using the three included screws. For optimal security and aesthetics, consider hiding the power cable behind a wall or ceiling. If the cable must be exposed, use a wire or cord cover for protection. Ensure the area where the wiring is located is monitored by a camera to receive notifications if tampering occurs.

7. Troubleshooting
7.1 Camera Offline
If a camera goes offline, check its power connection and ensure it is within range of the HomeBase 3 or your Wi-Fi router (if Multi-Bridge is enabled). If the issue persists, you may need to physically remove the camera, delete it from the app, and re-add it near the HomeBase 3.
7.2 HomeBase 3 Issues
If the HomeBase 3 experiences power failure or intermittent operation, verify the power adapter and check the internal hard drive. A faulty hard drive can prevent the HomeBase from functioning correctly. Contact eufy support if the issue cannot be resolved.
7.3 AI Detection Accuracy
AI detection may sometimes misidentify objects. Ensure activity zones are correctly configured to minimize nuisance notifications. The BionicMind AI is designed to self-learn and improve accuracy over time with continued use.
7.4 Video Playback and Download
While 24/7 footage is recorded, stitched and processed clips from Cross-Camera Tracking may not be directly downloadable from the app. Playback of these stitched clips might appear choppy due to processing in full resolution. For critical events, individual camera recordings can typically be downloaded.
8. Warranty and Support
For warranty information, technical assistance, or further support, please refer to the official eufy Security website or contact their customer service directly. Product protection plans are also available for extended coverage.
