strip, vertical strip, slanting strip and etc.
Noise: The video noise refers to the blurry video, poor video quality. It may result from the optical
system distortion or the hardware problem during the video transmission when recording.
Color cast: Usually the video is color containing RGB. When these three colors displayed in
abnormal rate, we can say color cast occurred.
Out of focus: The clear video presents abundant video details. The video definition decreases when
the distortion event occurs. The out of focus event may result from many sources such as video
transmission, processing and etc.
Overexposure: The color brightness refers to the image pixel intensity. Black is the darkest and the
white is the brightest. We use number 0 to stand for black and use number 255 to stand for white.
Once the brightness threshold of the whole image has exceeded the threshold value, it means the
image is over exposure.
Threshold: The value ranges from 1 to 30. System can generate an alarm once the value is higher
than the threshold you set here.

Important
The IVS plans are for the smart camera. If you do not set a rule here, user may not use the
intelligent functions in Behavior analytics (Chapter 3.14.3), Face detection (Chapter 3.14.4) and
People counting (Chapter 3.14.5) when you are connecting to a smart camera.
In this interface, user may quickly add an intelligent rule for one preset. The intelligent rule includes
human face detection, behavior analytics and people counting.
From main menu->Setting->Event->IVS plan, the interface is shown as below. See Figure 3-107.
