Power supply for ring outdoor wired camera

Hi All, I’m looking to buy an Outdoor wired camera. I have a mains supply that I can link in to but I can’t see the power supply. The one that comes with it is huge so I was hoping it had a plug in USB the same as the indoor ones. I want to replace the power supply with something much more compact so it can fit inside the adaptable box that already contains the garden Smart Tech. Any help offered will be gladly accepted! Thanks Dena
