10. User Tips
- Waterproofing for Outdoor Use: While the product is rated IP66 waterproof, some users have reported concerns about the waterproofing of the solar panel connection. For optimal outdoor performance and longevity, ensure all cable connections are securely tightened and, if necessary, apply additional weather-resistant sealant to prevent water ingress.
- 4G Signal Strength: As this camera relies solely on 4G connectivity, ensure a strong 4G signal at the installation location for reliable performance. Consider using a signal booster if the signal is weak.
- Battery Management: The camera's recording behavior adapts to battery levels. For continuous 24/7 recording, ensure the battery is above 85% and actively charging via the solar panel. At lower battery levels, recording may become event-triggered or limited to live viewing.
11. Troubleshooting (FAQs)
Q: What should I do if the camera shows offline in the APP device list?
- Check if the power supply connected to the device is normal.
- If there is an SD card in the device, remove the card and reboot the device and router to see if it can go online.
- Check the 4G card traffic. If the traffic is insufficient, top up in the app.
Q: What should I do if I can't watch the video on the card playback?
A: Make sure the video switch is turned on normally. If the switch is on but still no video, go to (Settings) -> (Video Settings) -> Formatting.
Q: What should I do if an abnormal alert occurs in the camera?
- Network Connection Failure: This indicates poor signal. Check if the antenna is connected properly and compare the mobile phone signal strength.
- Initialization Failure: If an SD card is present, remove it first and try again. If multiple attempts still result in initialization failure, contact the merchant for assistance.
12. Maintenance
- Cleaning: Regularly clean the camera lens and solar panel with a soft, damp cloth to ensure optimal performance. Avoid abrasive cleaners.
- Firmware Updates: Yoosee App and device firmware will be updated periodically. If prompted, please upgrade online to ensure the latest features and security.
- Connection Checks: Periodically inspect all cable connections for wear, damage, or loose fittings, especially for outdoor installations.
