Provided is a method for adjusting a video monitoring device for appropriately detecting video and/or errors occurring in accordance with the content of digital video signals. Also provided is a video monitoring device for appropriately detecting video and/or errors through learning from digital video signals. The video monitoring device comprises a video/audio monitoring unit that incorporates a memory in which threshold values are stored, and a parameter optimization learning unit. The video monitoring device is configured to determine that an error has occurred when all of a plurality of parameters varying in accordance with video signals exceed respective threshold values specified in accordance with monitoring items. At least two of the plurality of parameters are associated with each other, and the video monitoring device selects a set of threshold value groups stored in the memory in accordance with the content of the video and/or audio to be monitored. Through an analysis of error warning results, the parameter optimization learning unit performs learning and updates the threshold values on the basis of the learning result.
