New video pro doorbell purchased but not sure it’s safe for U.K. install

Hi,Ive just purchased the ring pro doorbell but it appears to differ from others that I've seen. There is no corner fixing attachment. There is just a bypass module but no v2 or other cable. It was purchased from a reputable dealer "Box". The packaging box is different but is clearly a Ring product. See pic. I am just wondering if I should keep it or return it. Any ideas/help gratefully appreciated. stuart.
