1. An apparatus for monitoring a beehive, the apparatus comprising:

  • a camera that captures a sequence of video frames of the exterior of the beehive at a predetermined frame rate, the sequence of video frames including at least a first video frame, a second video frame, and a third video frame; and

    ,a processor in communication with the camera system, the processor performs image analysis on the sequence of video frames to calculate an activity value that represents an estimate of the number of bees in the vicinity of the beehive, wherein the image analysis performed by the processor includes;

    generating a first difference frame by subtracting the second video frame from the first video frame;

    generating a second difference frame by subtracting the third video frame from the second video frame;

    generating a differential image frame by combining the first difference frame and the second difference frame using a logical AND operation;

    generating a modified differential image frame by performing a thresholding operation on the differential image frame;

    identifying a set of contours in the modified differential image frame by performing blob detection on the modified differential image frame;

    generating a count of the number of contours in the set of contours having an area that falls within a predefined range;

    calculating the activity value by multiplying the count by the predetermined frame rate; and

    ,storing the activity value on a storage device for display on a user device.
