1. A system that assesses the number and location of persons in a building, comprising:

  • at least two emitters;

    at least one doppler sensor entirely inside the building-that senses reflected radiation indicative of a reflection off of at least one person of emitted radiation from multiple ones of the at least two emitters; and

    a communicative network, wherein sensing data from at least one doppler sensor at the building is forwarded to a remote central hub that manipulates an absence of the sensing data from ones of the at least one doppler sensor to an indication of the number and the location of the persons in the building;

    wherein the remote central hub indicates to at least first responders the number and the location of the persons in the building.
