App Download and Account Creation
Download the official Foscam app from your device's app store (iOS App Store or Google Play Store). Follow the on-screen instructions to create a new Foscam account or log in if you already have one. This app is essential for camera setup, live viewing, and accessing all features.
Wi-Fi Connection
The FOSCAM B4 camera supports 2.4GHz Wi-Fi networks only. It does not support 5GHz Wi-Fi. During setup, ensure your smartphone is connected to a 2.4GHz Wi-Fi network for successful pairing with the camera. The camera's effective Wi-Fi range is approximately 70-80 meters in open, unobstructed areas, but actual performance may vary based on environmental factors and router strength.

3. Operating Instructions
Live View and Remote Control
Access the live video feed through the Foscam app. The camera supports Pan (355° horizontal) and Tilt (90° vertical) functions, allowing you to remotely adjust the viewing angle to cover a wide area without blind spots. Note that continuous live viewing is limited to 5 minutes to conserve battery life, as the camera is designed for motion-triggered events and on-demand viewing.

4. Maintenance
Battery Management
The integrated solar panel is designed to keep the 5000mAh battery charged. For optimal performance, ensure the solar panel is positioned to receive maximum direct sunlight. Regularly check the battery level via the Foscam app. A DC 5V/1A USB power adapter is not included for direct charging, but can be used if needed.
Cleaning and Care
Periodically clean the camera lens and solar panel with a soft, damp cloth to remove dust and debris. Avoid using harsh chemicals or abrasive materials that could damage the surfaces. Ensure the camera's mounting is secure.
Weather Resistance
The FOSCAM B4 camera is IP65 rated, meaning it is protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for outdoor use in various weather conditions, including rain and snow.

5. Troubleshooting
Common Issues and Solutions
- Camera not connecting to Wi-Fi: Ensure your Wi-Fi network is 2.4GHz. The camera does not support 5GHz Wi-Fi. Verify the camera is within the effective Wi-Fi range (70-80 meters in open areas).
- Limited continuous live viewing: The camera is designed for motion-triggered recording and remote live viewing only when needed. Continuous live viewing is limited to 5 minutes to preserve battery life. It is not intended for 24/7 streaming.
- Compatibility with third-party software/NVRs: The FOSCAM B4 does not support third-party software such as RTSP or ONVIF, nor does it work with web browsers, Foscam NVRs, NAS, or Blue Iris software. Foscam VMS supports adding the B4 to a cloud account only, not local accounts.
- Storage limitations: The camera does not have FTP storage access. It supports a maximum of 256GB Micro SD card or Foscam cloud storage.
- Power issues (red light blinking): This indicates low or no power. Ensure the solar panel is clean and receiving sufficient sunlight. If necessary, charge the camera directly using a compatible 5V/1A USB power adapter (not included).
