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:
•
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, you can adjust one or more of the following settings:
Note
Image noise will increase if you increase the gain.
•
Increase shutter speed and gain. Go to
Settings > Image
>
Exposure
and set
Max shutter
to a shorter time, and
Max gain
to a higher value.
If you are still experiencing motion blur, you can try one of the following:
•
Increase the light level in the scene.
•
Mount the camera so that objects move toward it or away from it rather than sideways.
Note
The depth of field gets shallower if you use a lens with a larger aperture.
•
Change to a lens with a larger aperture.
