Add Abnormal Event Detection Task

Abnormal event detection analysis refers to the analysis of abnormal events of people, vehicle, and other objects for purposes such as finding out security threat. The available abnormal event analysis types include perimeter protection (e.g., intrusion detection), street abnormal event analysis, prisoner abnormal event analysis, and people density analysis. You can add an abnormal event analysis task to define conditions such as time, device, and detection area for abnormal event analysis. Once an abnormal event analysis task is added, the specified device will perform abnormal event analysis in the specified detection area during the specified periods.
