Benefit from IR light in low-light conditions using night mode
Your camera uses visible light to deliver color images during the day. As the available light diminishes, you can set the camera to
automatically shift to night mode, in which the camera uses both visible light and near-infrared light to deliver black-and-white
images. Since the camera uses more of the available light it can deliver brighter, more detailed, images.
1. Go to Settings > Image > Day and night, and make sure that the IR cut filter is set to Auto.
2. To determine at what light level you want the camera to shift to night mode, set the Day-night shift priority to Day,
Night or None.
3. Enable Allow IR illumination and Synchronize IR illumination to use the camera's IR light when night mode is activated.
Reduce noise in low-light conditions
To reduce noise in low-light conditions, you can adjust one or more of the following settings:
• Set the exposure mode to automatic.
Note
A high max shutter value can result in motion blur.
• To slow down the shutter speed, set max shutter to the highest possible value.
• Reduce sharpness in the image.
• Set the max gain to a lower value.
Reduce motion blur in low-light conditions
To reduce motion blur in low-light conditions, adjust one or more of the following settings in Settings > Image > Exposure:
• Set Exposure mode to Automatic and turn on Motion-adaptive exposure.
Note
Motion-adaptive exposure works best when you move the Blur-noise trade-off slider fully toward Low noise.
• Move the Blur-noise trade-off slider toward Low motion blur.
Note
When you increase the gain, image noise also increases.
• Set Max shutter to a shorter time, and Max gain to a higher value.
If you still have problems with motion blur:
• Increase the light level in the scene.
• Mount the camera so that objects move toward it or away from it rather than sideways.
Handle scenes with strong backlight
Dynamic range is the difference in light levels in an image. In some cases the difference between the darkest and the brightest
areas can be significant. The result is often an image where either the dark or the bright areas are visible. Wide dynamic range
(WDR) makes both dark and bright areas of the image visible.
