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.
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.
Stabilize a shaky image with electronic image stabilization (EIS)
Electronic Image Stabilization (EIS) can be used in environments where the product is mounted in an exposed location and subject to
vibrations, for example, wind or passing traffic.
EIS makes the image smoother, steadier and less blurry. It also reduces the file size of the compressed image and lowers the
bitrate of the video stream.
Note
The image is cropped slightly when EIS is enabled, lowering the maximum resolution.
1. Go to Video > Installation > Image correction.
2. Turn on Image stabilization.
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.
Image without WDR.
