1. A video analysis apparatus comprising:

  • a memory that stores a program; and

    a processor configured to run the program stored in the memory that is configured to cause the processor to;

    determine a group including a difference frame having a data size equal to or larger than a predetermined threshold value among a plurality of groups for an encoded video data received from an imaging device capturing a monitored base, the group including a plurality of frames in a chronological order, the encoded video data being divided into the plurality of groups,perform a decoding process on the plurality of frames of the group determined to include the difference frame having the data size equal to or larger than the predetermined threshold value,perform a detecting process that detects a moving object by performing image analysis on the plurality of frames on which the decoding process has performed, anddetermine whether the group satisfies at least one of(a) including the difference frame having the data size equal to or larger than the predetermined threshold value,(b) an average value of the data size of the difference frame included in the group is equal to or larger than the predetermined threshold value, or(c) the difference frame having the data size equal to or larger than the predetermined threshold value and at least one other difference frame being continuous by a number that is equal to or larger than a predetermined number.
