What's in the Box?
Before you start, it's essential to know what comes with your eufyCam S4 (2 Pack). The package includes two eufyCam S4 cameras, a HomeBase 3 (or compatible HomeBase), mounting brackets, screws, and anchors, as well as USB and Ethernet cables for the HomeBase. You'll also find quick start guides and warranty information.
Take a moment to inventory all components. If anything is missing, contact eufy support immediately. Having all parts ready will make the installation process smoother.
- Check that you have both cameras and the HomeBase.
- Ensure the mounting brackets and screws are included.
- Verify the Ethernet and USB cables are present for HomeBase connection.
Choosing the Perfect Camera Locations
The effectiveness of your outdoor security depends largely on camera placement. For maximum coverage, consider entry points like front and back doors, ground-level windows, and garages. The eufyCam S4 has a wide field of view, but placing it 7-10 feet high with a slight downward tilt will capture faces and license plates clearly.
Avoid pointing cameras directly at the sun to prevent glare and image washout. Also, ensure the cameras are within range of your HomeBase (typically up to 300 feet in open air). If you have a large property, you may need to adjust placement or consider adding a Wi-Fi extender.
For more comprehensive protection, you might also explore other eufy products like the eufy Permanent Outdoor Lights E22 to illuminate dark areas, which can enhance your camera's night vision.
- Mount cameras at 7-10 feet for optimal angle.
- Cover all ground-floor entry points.
- Keep cameras within 300 feet of the HomeBase.
Mounting the eufyCam S4
Once you've selected the spots, it's time to mount the cameras. Use the included mounting bracket as a template to mark screw holes. Drill pilot holes, insert anchors, and secure the bracket with screws. Then, attach the camera to the bracket by aligning the grooves and twisting until it locks.
For brick or stucco surfaces, you may need a hammer drill and masonry bits. If you're not comfortable drilling, consider using heavy-duty adhesive mounts designed for outdoor use. Ensure the camera is firmly attached and can be adjusted to the desired angle.
If you're also using other smart home devices, like the eufy Smart Lock C32, you can integrate them into your security ecosystem for a cohesive setup.

- Use the bracket as a drill template.
- For masonry, use appropriate drill bits and anchors.
- Adjust the camera angle after mounting for best view.
Setting Up the HomeBase
The HomeBase acts as the central hub for your eufyCam S4 system. Connect it to your router using the Ethernet cable and plug it into a power outlet. The HomeBase also has a USB port for local storage (sold separately) if you want to store footage without a subscription.
Download the eufy Security app on your smartphone and create an account or log in. Follow the in-app instructions to add the HomeBase. The app will guide you through connecting to your Wi-Fi network (2.4GHz is recommended for stability).
Once the HomeBase is online, you can proceed to sync your cameras.
- Place the HomeBase in a central location for best signal.
- Use a wired Ethernet connection for reliability.
- Enable local storage via USB for backup.
Syncing Your Cameras
To sync a camera, press the sync button on the camera (usually on the back) and then press the sync button on the HomeBase within a few seconds. The camera's LED will turn blue when connected. Repeat for the second camera.
In the app, you'll see both cameras appear. Name them according to their location (e.g., 'Front Door', 'Backyard') to easily identify them in notifications. The app will also prompt you to update firmware if available; do this to ensure optimal performance.
After syncing, you can adjust camera settings like motion detection zones, sensitivity, and recording schedules. The eufyCam S4's AI can distinguish between humans and animals, reducing false alerts.
- Sync one camera at a time to avoid confusion.
- Update firmware after setup for best features.
- Customize motion zones to focus on critical areas.
Testing and Final Adjustments
After setup, test each camera by walking through the detection area. Check live view to ensure the angle and coverage are correct. Adjust if necessary. Also, test the night vision and two-way audio to confirm they work.
If you experience connectivity issues, try moving the HomeBase closer or using a Wi-Fi extender. Also, ensure your router's firewall isn't blocking the cameras. The eufy Security app provides troubleshooting tips.
For additional security, consider pairing your eufyCam S4 with other eufy devices like the eufy Robot Vacuum Omni C28 to automate home cleaning while you're away, creating a fully smart home experience.
- Walk-test each camera to verify detection.
- Check night vision and audio quality.
- Adjust camera angles based on live view.
With your eufyCam S4 2-Pack now installed and configured, you can enjoy peace of mind knowing your outdoor spaces are monitored 24/7. Regular maintenance, such as cleaning the lenses and checking battery levels, will keep your system running smoothly.
