A:Answer The Ring system has a delay and relies heavily on a strong, fast wifi signal; poor wifi will make the delay even worse and may even cause the Ring to lose signal. It's really frustrating, especially for a doorbell system. They have a wifi extender, but I've tried to add it and isn't very good. Your situation of 400 ft obstructed distance is far for even a decent router. Consider getting a mesh wifi system with one unit close to your door or look into a wired system. Ring has a wired version but it's expensive and is POE which most people don't have. In my opinion, pass on the Ring system. Great concept, but flawed design both in product and App; both unreliable, slow and a pain to set up. The delays and range are infuriating. The device appears to be water resistant but the lens needs to be free of water/debris to work properly.
