See and speak with visitors at front doors, gates, and other entrances before letting them in. For a complete intercom system, you’ll need one master station and one substation. They’re connected by a single cable, which carries both data and power.

Use master stations to call and receive calls from substations, while checking who’s there on the LCD display. They have a touch screen for opening the door, transferring or putting the call on hold, and scrolling through the call history.

Substations have a wide-angle IP camera to capture a large viewing area and stream video to the master station, as well as a microphone and speaker to relay audio. When a visitor presses the button, these substations call the first of up to six programmable numbers, and then dial the next number if the first is busy or there’s no answer. An LED indicator shows when the substation is calling and when the call is answered, which helps visitors know when to speak. They have an auxiliary output so you can unlock the door from the master station, reducing contact between people and the chance of spreading disease. Made of stainless steel, the substation’s faceplate won’t rust or deteriorate from exposure to water, harsh weather, and chemical splashes. They’re rated IP66, meaning they keep out dust when there’s continuous airflow and they’re protected against washdowns.
