Broken plug spotlight camera

Hi, I’ve recently moved house and took our Ring cameras from our old property with us. Unfortunately during the move there was damage to the plug for our Ring spotlight camera so I chopped it from the cable so nobody would use it if I wasn’t around

I’ve recently come to install the camera and have sourced a new plug however I’m not sure what size fuse it should have installed.

Appreciate changing the plug has no doubt voided my warranty but the produce is 2+ years old anyway!

Many thanks
