On a Ring video, it says there is an Adapter for RinG Solar for Spotlight
Says it is available on the Ring site under Accessories
I dont see it there.
It is the plug that plugs into the back of the Spotlight Cam Battery unit. THEN attached using a wire to the Solar panel.
If you bought them as a set everything should be in the box.
I have 3 solar panels. Take the cover off the back of the camera with screwdriver that came with unit. Plug wire from solar into camera, thats it. No adapter is needed. Do not plug into battery compartment. Its the camera plate, it has 1 screw. Hope this helps.
