The WolffTracker can be placed on the outside walls, doors, and windows of almost any house or building that is not shielded with metal. When there is a person within proximity of one of the WolffTracker sensors, a set of high power LEDs will blink until the person has left that area. If multiple sensors are placed around the building, operators can have an indication of the location of the person(s) inside. This can provide lifesaving information prior to breaching a door or window, decrease response time to a suspect’s movement to an opening, or indicate the best locations to deploy chemical munitions or diversionary devices.
