I have a customer that is looking for a Video door phone solution.
They currently have IP phones. They would like it that when the button is pressed it calls the phone but they also want an easy way to see who is at the door. They can put a cheap tablet up if that is what is needed. Any ideas? It has to be a bit rugged as it is not in the best neighborhood. A big plus would be if it supports codes that can be entered, but they are not willing to spend too much more for that.
Thank you
