It seems that the developers of this system forgot that the most important feature is opening the door. This replaced an old Door King system on our building from the 90s. The Door King worked faster and better. It did not have a touchscreen or a camera, but it was possible to open the door. When someone calls you from the door with this AIPHONE IXG garbage, you have to navigate through several levels of menu items in order to open the door. After that, it takes 20 or 30 seconds to connect. Then, about 50% of the time the action to open the door fails. Delivery drivers tend to walk away rather than wait for this high-tech front-door iPad to let them in. I don’t even have time to go into the problems with the user interface of the system at the front door. Most people have trouble figuring out how to get in.
