1. An apparatus for electronic motion detection, the apparatus comprising:

  • a housing;

    first and second sensor clusters mounted in spaced, forward facing positions within the housing, the first and second sensor clusters aligned in the same horizontal plane;

    a span adjustment member located within the housing and interposed between the first and second sensor clusters, the adjustment member configured to adjust the horizontal spacing between the first and second sensor clusters, the span adjustment member providing a variable binocular disparity between the first and second sensor clusters;

    an elevation adjustment member located within the housing and at least partially supporting the first and second sensor clusters, the elevation adjustment member configured to adjust the elevation of the first and second sensor clusters;

    each of the first and second sensor clusters including a left binocular plurality of passive infrared sensors and a right binocular plurality of passive infrared sensors, the left and right binocular pluralities being separated by a fixed distance to provide fixed binocular disparity;

    the first and second sensor clusters defining respective left and right overlapping fields of view;

    detection circuitry located within the housing, the detection circuitry communicatively disposed with the first and second sensor clusters, the detection circuitry processing respective detection signals relative to an intruder received from the left and right binocular plurality passive infrared sensors of each of the first and second sensor clusters;

    the detection circuitry including a memory accessible to a processor, the memory including processor-executable instructions that, when executed cause the processor to;

    specify detection validity at a first time, t1, based on the functional values of the detection signals as logical expressions with functional arguments,specify detection validity at a second time, t2, based on the functional values of the detection signals as logical expressions with functional arguments,compare detection validity at the first time, t1, and detection validity at the second time, t2, to identify direction of movement, andspecify instructions for indicating the direction of movement;

    a display mounted in the housing and communicatively disposed with the detection circuitry, the display for receiving the instructions for indicating the direction of movement and providing a visual indication to classify the intruder as one of moving left to right, right to left, and stationary; and

    an antenna associated with the housing and positioned in communication with the detection circuitry, the antenna for sending wireless detection signals to a vibrating monitor device,wherein the vibrating monitor device is configured to receive the instructions for indicating the direction of movement and providing a vibratory indication to classify the intruder as one of moving left to right, right to left, and stationary.
