I'm in the planning stages for running ethernet cable throughout the house. Planning to install several POE cameras. Going to put a camera by the front door entrance. Is there a POE video screen device (like an iPad) that can be mounted inside the house by the front door and when someone is at the front door I can turn on the device and view who is at the front door? Does something like this exist? I'm not interested in a Ring doorbell. Just want to be able to access the view from the Dahua Starlight camera while standing on the other side of the door.
