Eufy Security eufyCam 2C Pro 2 wifi connection

I can’t get Wi-Fi signal outside the house even with extender but where I want to mount the camera there is a strong signal from my neighbour. Can I sync the camera and hub with router at home first and then move the camera outside to be connected to neighbour’s wifi? That way both camera and hub will be online but on different wifi. Thanks

I have a homebase 2 and the cameras need to connect to it, so WiFi extenders won’t help unfortunately in my case.

No that won’t work because the 2C Pro can only connect to the HomeBase’s Wi-Fi.
The HomeBase acts as a extender / repeater of your homes Wi-Fi and only allows eufy devices to connect to it.
What you can do is move the HomeBase closer to the camera while still having a good Wi-Fi connection to your homes router.
