How to decide the cable size for Ring Floodlight Pro?

How to decide what cable size should be used for Ring floodlight Pro. For example, 2.5mm^2?

What are the downsizes if an oversize cable is used? For example , if 2.5mm^2 is used for 1.5mm^2?

Hi @user70959. We have this Help Center page with the steps for installing a Floodlight Cam Wired Pro. If you need more information, like what wire size to use, and no other neighbor here has a suggestion, I recommend consulting a qualified electrician for help.
