Parameter Function
Stripe The strip occurs when the device is old or there is electronic
interference. There may be cross 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 100. System can generate an alarm
once the value is higher than the threshold you set here.
