Abstract
A self-contained collision warning device warns of possible collisions between people and between people and moving objects on opposite sides of doors and other visual barriers. Motion sensors detect the presence of people or moving objects and activate indicators that warn of the presence of unseen people and moving objects. The device can be mounted to a door or wall without modification to the door or wall or access to electrical power.
