Solar panel but battery low

My outdoor camera has been displaying two bars of battery but is permanently connected to a eufy solar panel.
I have turned the camera off for a few days but the battery has not charged up.

Any ideas?

Hi,
Not sure if an update to the cameras did something but switch the power source to solar panel. Mine use charge via solar even when battery was selected. When I swapped to solar panel mine started charging. Good luck, hope this helps.

Thanks Cody.

The solar input is still selected on this camera. I have other Eufy cameras on their own Eufy solar panels which work normally.
