Event Category-All IVA Events

For cameras with embedded video content analysis, it is capable of detecting IVA (Intelligent Video Analysis) events, such as moving object detection, loitering detection, and tampering detection. The embedded video content analysis, superior to conventional motion detection function, is capable of distinguishing between creature’s motions and still backgrounds or natural movements like swaying trees, waves or sunset so as to prevent the false alarms from environmental noise. With the tampering detection, it can detect incidents such as shooting redirection, blocking or defocusing of cameras, or even spray-painted. Additionally, a suspicious object in the predefined detection region will trigger alarms once the dwelling time of the object is longer than the given time.

If you select All IVA Events category, all detected IVA events will be included in the search.

If you want to change the parameters of IVA, such as detection region, loitering duration, etc, please link to the camera's web setting page to modify the values.

Event Category-All DI Events

The motion events represent that there is Digital-Input signal detected by the camera and its corresponding information, such as DI-High or DI-Low signal and the time of occurrence, is transmitted and recorded in the database of the station. For some models, the rising means from normal state to trigger state, and the falling means from trigger state to normal state.

If you select All DI Events category, all triggered DI signals will be included in the search.

If you want to change the DI/DO setting of the cameras, please link to the camera's web setting page to modify the settings.
