the camera settings are very easy once fixed access, it simply turns the infrared module and the three knobs become accessible.
The mounting kit is complete, the batteries are already charged, but a quick phone charger never wrong!
in a December day (gray), the solar panel sends about 8,3V, sunlight must have 10V.
In any case, even with short winter days the batteries can be recharged in good conditions!
And purpose, the lighting: I use it in a shed shelters wood about 6m, and the spot perfectly illuminates the shelter, so it's to my taste a great product, and the price is above average justified!
