Configure your device
3. Go to ImageSource/I0/Sensor > Low latency mode and select On.
4. Click Save.
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 fast moving objects that require a fast or fixed shutter, select Automatic aperture.
•
To maintain a longer depth of field or focus range, select Automatic shutter.
•
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.
•
If you need full control of all parameters, select Manual. This is mostly useful for scenes with little change in lighting.
•
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.
3. To use the built-in IR light when the camera is in night mode, turn on Allow illumination and Synchronize illumination.
4. If you use an accessory IR illuminator, turn on Allow illumination and Synchronize illumination to use IR light when the
camera is in night mode.
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.
Optimize IR illumination
Depending on the installation environment and the conditions around the camera, for example external light sources in the scene,
you can sometimes improve the image quality if you manually adjust the intensity of the LEDs. If you have problems with reflections
from the LEDs, you can try to reduce the intensity.
1. Go to Video > Image > Day-night mode.
2. Turn on Allow illumination.
3. Click
4. Adjust the intensity.
