The Seco-Larm Enforcer Wireless Video Door Phone Kit consists of an outdoor video phone station and an indoor monitor for 2-way audio communication and the ability to see who you're talking to at your front door. When someone moves in front of the door phone's camera or presses its button, the door phone calls the indoor monitor for you to answer and talk with your guest. The video door phone includes built-in IR LEDs for nighttime operation and IR sensors for motion detection and motion activation. The door phone camera has a 170° field of view with adjustable pan and tilt angle to accommodate a variety of installations.
