AXIS M5075-G PTZ Camera
Configure your device
Select exposure mode
To improve image quality for specific surveillance scenes, use exposure modes. Exposure modes lets you control aperture, shutter
speed, and gain. Go to Video > Image > Exposure and select between the following exposure modes:
•
For most use cases, select Automatic exposure.
•
For environments with certain artificial lighting, for example fluorescent lighting, select Flicker-free.
Select the same frequency as the power line frequency.
•
For environments with certain artificial light and bright light, for example outdoors with fluorescent lighting at night and
sun during daytime, select Flicker-reduced.
Select the same frequency as the power line frequency.
•
To lock the current exposure settings, select Hold current.
Benefit from IR light in low-light conditions by using night mode
Your camera uses visible light to deliver color images during the day. But as the visible light diminishes, color images become less
bright and clear. If you switch to night mode when this happens, the camera uses both visible and near-infrared light to deliver bright
and detailed black-and-white images instead. You can set the camera to switch to night mode automatically.
1. Go to Video > Image > Day-night mode, and make sure that the IR-cut filter is set to Auto.
2. To set at what light level you want the camera to switch to night mode, move the Threshold slider toward Bright or Dark.
Note
If you set the switch to night mode to occur when it's brighter, the image remains sharper as there is less low-light noise. If
you set the switch to occur when it's darker, the image colors are maintained for longer, but there is 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 Video > 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.
Note
When you reduce the max gain, the image can become darker.
•
Set the max gain to a lower value.
•
If possible, move the slider under Aperture toward Open.
•
Reduce sharpness in the image, under Video > Image > Appearance.
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.
