Event Category- All IVA events

If you select the All IVA events category, all detected IVA events will be included in the search. Cameras with embedded intelligent video content analysis are capable of detecting IVA events such as moving objects, loitering, and tamper detection.

The embedded video content analysis, superior to the conventional motion detection function, is capable of distinguishing between creature’s motions, static backgrounds or natural movements such swaying trees, waves or sunsets to prevent false alarms from environmental noises.

With camera tamper detection, it can detect incidents such as camera redirection, blocking or defocusing of cameras, or even spray-paint. Additionally, a suspicious object in the pre-defined detection region will trigger alarms once the dwell time of the object is longer than the given time.

You can click Add or Remove to change the search criteria items.

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

Event Category- All DI Events

If you select All DI Events category, all triggered DI signals will be included in the search. The DI events signify that there is a Digital-Input signal detected by the camera; its corresponding information such as DI-Trigger or DI-Normal signal and the time of occurrence are also transmitted and recorded in the database of the server.

You can click Add or Remove to change the search criteria options.
