Gen 3 Power Source

I am trying to power a Gen 3 stick up camera battery model. The recepticle is 30 feet from the camera. The only power adapter I have found is the Ring model. Two problems, one is that it’s too short and secondly it has the adapter box in the middle which makes it impossible to hide. And the solar panel is too short to reach from where it would have to be mounted.

Any suggestions on what I can do?
