2N Indoor View WiFi 7" HD Touchscreen Display, Black. The 2N Indoor View runs on our very own operating system. We’ve made sure that no one can listen in or record residents’ conversations. The resident can see what is going on in places where no intercom has been installed, and there is only an IP camera (e.g., a hallway, yard or garage). The resident can turn on the air-conditioning, lighting or call the lift directly from the display on their unit. The unit can send up to 3 different HTTP commands.
