Fitting a wired outdoor Camera

Hi, new here. Just purchased an indoor/outdoor ring camera. The box contains two cables, one of which is thicker than the other, I can see that they can be joined together to extend the overall length. However, I will only need to use the thinner of the two cables to secure my camera on an outside wall and plugging the camera into my garage. My question is this: Is the thinner cable weather proof and can therefore be used on my outside wall?
