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 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:
•
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.
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.
1. Go to
Settings > Image > Wide dynamic range
.
2. If required, turn on WDR.
3. Use the
Contrast
slider to adjust the amount of WDR.
