The GeoVision GV IB 65 Infrared Button detects infrared movement within 1.18 to 4.72 inch and allows you to open the door with a wave of hand. The touchless sensor eliminates the need to contact the button and keeps your hands clean when entering or exiting places such as hospitals, restaurants or stores. In addition, the built in relay function allows you to program the door opening time to enhance security.
