1. A door lock detection system, comprising:

  • a magnetic field system configured to emit one or more magnetic fields, wherein;

    the magnetic field system comprises a strike plate and a bolt;

    the strike plate comprises an opening through which the bolt is configured to extend;

    the magnetic field system emits a first magnetic field in accordance with the bolt having a first position with respect to the opening of the strike plate; and

    the magnetic field system emits a second magnetic field, distinct from the first magnetic field, in accordance with the bolt having a second position with respect to the opening of the strike plate, wherein the bolt in the first position does not extend through the opening by more than a threshold amount, and the bolt in the second position extends through the opening by more than the threshold amount; and

    a magnetometer system configured to detect, and to discern differences between, the first magnetic field and the second magnetic field.
