Surveillance captured the Black and White Ghosts

The surveillance camera captured the Black and White Impermanence scaring people in the middle of the night for one of the following reasons: The environment of the surveillance camera was dark, resulting in a black-and-white image; the surveillance camera used a chip that turned from color to black, which would automatically switch to black-and-white mode when there was insufficient light; the image of the surveillance camera malfunctioned, which could be due to color storage and transmission problems or the aging of the camera; the poor connection of the surveillance video line caused problems with the image signal. If you feel afraid, you can try to ease your fear, such as chanting the name of Buddha or Guanyin Bodhisattva.

There were several possibilities for the surveillance camera to turn black and white. One possibility was that the camera's function was limited. When there was sufficient light, the camera would capture a color image, but when there was insufficient light, the camera would automatically switch to infrared night vision mode, causing the image to turn black and white. In this case, you can change it through the function settings. The other possibility was that the camera's image had a malfunction, including color storage and transmission problems, or the camera and the camera were aging and needed to be replaced. In addition, the problem with the video transmission line could also cause the surveillance screen to turn black and white. It was necessary to check the connection line and replace the cable. If the above methods cannot solve the problem, it is recommended to seek the help of professional technicians.

Black-and-white surveillance cameras usually had no sound. Unless the camera had a built-in pickup device or another pickup device, the sound could only be heard. To record, a hard disk recorder with a pickup device and audio and video synchronization was required. Under normal circumstances, the surveillance cameras on the road could not play a practical role due to the noisy environment and the movement of pedestrians. Recording was usually done indoors or outdoors. Under indoor conditions, the sound could generally be heard within 20 meters, while outdoors, due to the influence of outdoor noise, the sound could generally only be heard within 15 meters. In general, the main function of the surveillance camera was to record video, and the recording of sound required additional equipment and settings.

The Black and White Impermanences were nicknamed the Soul Guide.
