2) Obstacle
If there’re obstacles in front of the camera, there will be c false alarms which occupy
NVR smart resources. In addition, large obstacle might block target you are really
interested in. Scene in picture below is not an appropriate one for detecting.
3) Strong light
In some scenarios, strong light interference makes a target hard to be detected.
Strong light generally can be divided into two kinds: strong background light and
strong foreground light.
Strong background light makes foreground target totally dark, as what is shown
picture below, the man in corridor looks like a shadow. WDR or BLC function is
recommended in this scene.
