If the live video stream that you are viewing is dark or you are recording at night, you can fix poorly lit frames by turning off the infrared-cut filter on cameras that support infrared imaging.

What you should know

The IR-cut filter settings only appear for Axis day-and-night cameras. Day-and-night cameras use infrared light to automatically adapt to the ambient lighting of a given scene. To achieve this, a day-and-night camera camera uses an IR-cut filter, which prevents or allows infrared light to reach the camera's image sensor.

To further illuminate dark or dimly lit scenes, some cameras are equipped with a white LED light. You can set the brightness of the white light, as well as configure all camera-related settings directly from your camera's web page. For more information about infrared light, day-and-night camera cameras and white LED light, see the Axis website.


  1. Click the tile that is displaying the poorly lit live video, and then click Camera options () (Silverlight video player).
    Only camera options that are supported by your camera appear in the Camera options drop-down menu. If your camera does not support any of the available options, this menu does not appear.
  2. Click one of the following settings:
    Turn off IR-cut filter
    Turns off the camera's infrared-cut filter, so that the camera can see infrared (IR) light. As a result, black and white video is produced. Use this setting at night or when there is not enough light in the scene that is being recorded. By turning this setting off, night mode on day-and-night cameras is enabled.
    Turn on auto IR-cut filter
    Turns on automatic mode of the camera's infrared-cut filter. In this mode, infrared (IR) light is automatically filtered out when there is ample light in a scene, and then used when the scene is poorly lit. Use this setting when you do not want to manually control the IR-cut filter, and you want the ambient light of a scene (or the rising and setting of the sun) to dictate whether or not infrared light needs to be filtered out. For most installations, it is recommended to turn on the automatic mode. By turning on automatic mode, the day-and-night cameras switch between day mode and night mode, as required.
    After a few seconds, the infrared light turns the scene to black and white. During the day or when there is ample light in the scene that is being recorded, click Turn on IR-cut filter to record video in color.
    IMPORTANT: By default, the automatic mode is turned on for cameras that support the IR-cut filter option.
  3. To add additional light to a poorly lit scene, click the following:
    Turn on white light
    Turns on the white LED light that is embedded within the camera. Use the white light when the ambient light is insufficient and you need to add light to a scene. It is recommended to turn on the white light only when required and not to keep it on permanently.


The following image shows how turning off the IR-cut filter changes the video stream from full color video to black and white, thus making it easier to see images at night or in low light. In this example, image A has the IR-cut filter turned on; image B has the IR-cut filter turned off.
