Video Intercom for Door

When someone presses the button on the outdoor unit, the indoor monitor will turn on, ring and show the video. You can see who is outside & press the "talk" button to talk with the people outside. You can also see & listen to outside sounds even if no one presses the outside button. This 2-way communication is an inexpensive and effective way to talk with the people at the door without actually opening the door. You can see, hear & speak.
