Select the Select All check box and all the following items will be selected.
The threshold value range is 1-100 and the default value is 30. When the output value is
higher than the set threshold, the system triggers an alarm.
Parameter Description
Stripe
Stripe refers to the interference in video due to device aging or electronic
interference, such as horizontal and vertical stripes or diagonal stripes,
which may cause interference to visual sense.
Noise
Video noise can be defined as the image quality degradation caused by
optical system distortion or hardware device during transmission.
Color Cast
Generally, video images are color images that contain color information,
such as RGB. When these three components in the image appear in some
unusual proportion, it means that the image has a color cast.
Out of Focus
The image with good definition contains rich details. The reason for the
image definition decline is that the generation of blurring phenomenon.
Image blurring is a common image quality reduction problem. In the process
of image acquisition, transmission and processing, many factors will cause
the image blurring, which is defined as out of focus in video diagnosis
Overexposure
The brightness of the image refers to the intensity of image pixels. Black is
the darkest while white is the brightest. Black is represented by 0 and white
is represented by 255. It indicates the brightness degree of the image. When
the brightness value of the whole image exceeds the threshold value, it is

3.10.2 Smart Plan
The smart plan is for the smart network camera. If you do not set a rule here, you cannot use the
intelligent functions in IVS (Chapter 3.10.3), Face detection (Chapter 3.10.4) and People counting
(Chapter 3.10.5) when you are connecting to a smart network camera.
There are two types to realize intelligent analytics function.
Note
Smart network camera supports intelligent functions: Some smart camera supports the intelligent
functions. For NVR, it just displays the intelligent alarm information from the smart network camera
and set or playback the record file.
NVR supports intelligent functions: The connected network camera does not support intelligent video
analytics function. The NVR supports the analytics function.
In this interface, you can quickly add an intelligent rule for one preset. The intelligent rule includes human
