Simple additional camera for existing Ring System?(in the UK)

Hi, I have an existing Ring System, with multiple floodlights and cams, chat facility on each, etc. But it would be good to have a simple solar powered wifi camera to overlook one area, but I don't need all the additional functionality, as these increase the product cost. Is there a "camera-only" cam that I can add to the Ring system? The cam will be external, sited very high up, which makes the extra features (like voice chat) unusable. Are there any products that can help, please ?
