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, move the Threshold slider toward Bright
or Dark.
3. Enable Allow IR illumination and Synchronize IR illumination to use the camera's IR light when night mode is activated.
Note
If you set the shift to night mode to occur when it's brighter, the image remains sharper as there will be less low-light
noise. If you set the shift to occur when it's darker, the image colors are maintained for longer, but there will be more
image blur due to low-light noise.
Reduce noise in low-light conditions
To reduce noise in low-light conditions, you can adjust one or more of the following settings:
• Adjust the trade-off between noise and motion blur. Go to Settings > Image > Exposure and move the Blur-noise
trade-off slider toward Low noise.
• 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.
Note
When you reduce the max gain, the image can become darker.
• Set the max gain to a lower value.
• Open the aperture.
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:
• 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:
