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.

If you select

database of the server.
