Need help with set up

I need some help with my Ring Ring 3 Plus DoorbellI would like it thatAlexa notifies me on all devices only ifSomeone has opened my gate and stepped onto the driveway. I am facing a road with a footpath and at the moment it appears to pick up cars and people going past. I’d like those recorded, especially if they are loitering around outside or a car has pulled up and parked outside my house.I would like for my 3 TV’s to show the front door when I say “Alexa Show me the front door” two of my TVs don’t appear to work with this they are Sony TV and Samsung TV. The LG TV if it is switched on Alexa will say OK then it will just say “Loading” and nothing happens.I’d also like a PC monitor to show front door too if that is possible when asking an alexa.On the alexa device that I say “Show me the front door” our voice should be relayed to the doorbell and the person at the door should relay onto the echo dot.I have good WiFi connection, I am hearing I may need firestick though one LG TV has the amazon app on it. Is that right?Kind RegardsJustin
