@Bruno_Bernardino Thank you for reaching out to eufy! Sorry to hear about the issue with your baby monitor.
Normally, the wireless transmission distance of the SpaceView baby monitor system is 460ft (140m). But the actual range of transmission distance varies depending on many factors such as the thickness of walls, obstacles inside the house.
If there are several walls between the two devices, that might strongly affect the connection. Please let us know if that is the case.
Please also try the updating the firmware of the baby monitor and camera(s) to the latest version via https://www.eufylife.com/support/5505/spaceview-baby-monitor
For the camera(s):
Connect the camera to your computer. Copy the “Camera.bin” to the SN93700BU folder. The camera will upgrade automatically.
For the monitor:
Connect the monitor to your computer. Copy the “Monitor.bin” to “SN93701PU”. There will be a progress window displayed on the monitor.
Note:
-
The baby monitor’s included cable doesn’t support data transfer, so please use a different USB cable for the upgrade.
-
Upgrade both the monitor and camera(s); the system can work normally only when all devices are on the same version.
If that doesn’t resolve the issue, please reach out to support@eufylife.com. We will have the customer support team to assist you with this case.
