Does Wyze have a solar panel with built-in battery to power a v4 camera?
No
No. Even most after market solar panels, some have a small battery just to level out fluctuations but not intended to power something at night or on dark days. I’m sure there are ones out there with a built in battery pack but you can do the same thing by running solar panel → battery pack with pass through power feature → camera. Use a weatherproof box as needed for the battery pack and connections.
