In the daily use of Hikvision POE camera, color cast often occurs in the monitoring screen. If this problem is not handled in time, it will not only affect the clarity and accuracy of the monitoring screen, but also cause great trouble to the user experience.
Color Cast Problems Caused by Different Reasons
By Environmental Interference
When the monitoring screen has local color cast, such as purple or yellow, it is very likely that there is an interfering light source in the environment. For example, in some places decorated with colored lights, or there are special materials such as colored glass around, these may affect the imaging of the camera.
Solution: Carefully check the monitoring environment to check whether there is the above-mentioned interfering light source. Once found, try to remove the interfering light source; if it cannot be removed, consider changing the type or position of the interfering light source. In addition, by adjusting the angle of the camera lens to avoid direct exposure to the interfering light source, the color cast problem can also be effectively solved.
By Improper White Balance Setting
When the color of the object presented by the camera is significantly different from the actual color, it is likely that the color temperature of the light in a special scene or special time period exceeds the default automatic adjustment range of the Hik camera.
Solution: For cameras with menu functions, you can enter the settings menu and find the white balance mode option. According to the actual color temperature of the on-site environment, select the appropriate white balance mode and bring the color temperature into the adjustable range of the camera to achieve image color balance.
By ICR filter Switching Stuck
If the monitoring screen appears partially or completely pink or reddish, it is usually caused by the ICR filter stuck. In this case, the color restoration function of the camera will be affected, resulting in abnormal screen color.
Solution: First, power off and restart the device, then restore the device to factory settings, and upgrade the firmware to the latest version. If the screen is still color-biased after completing the above operations, it can be basically determined that the ICR filter is stuck. At this time, it is recommended to contact after-sales maintenance personnel in time for professional inspection and replacement.
By Poor Device Contact
Sometimes, the following situation may occur: when viewing the surveillance screen on the APP, the display is normal, but on the recorder, red, green and other color bars appear, and even accompanied by water ripples. This situation is likely caused by poor connection between the devices.
Solution: First, carefully check whether the connection between the recorder and the display is firm and ensure that there is no looseness or detachment. At the same time, upgrade the device versions of the camera Hikvision POE and the recorder to the latest version to avoid compatibility issues caused by too low software versions.
How to Keep the Picture in Color?
In some low-light working environments, the camera will automatically turn on the infrared light to ensure the clarity of the picture, and the picture will switch to black and white mode. If you want the picture to always be displayed in color, you can set it as follows:
Solution: Access the Hik CCTV camera setting interface through the web page and find the infrared light and day and night mode options. Turn off the infrared light and set the day and night mode to daytime. It should be noted that after turning off the infrared light, in order to ensure that a clear picture can still be captured in a low-light environment, it is recommended to add a fill light to the camera to provide sufficient light.
