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 IR illumination and Synchronize IR
illumination.
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 IR illumination if you manually adjust the intensity of the LEDs.
1. Go to Video > Image > Day-night mode.
2. Turn on Allow illumination.
3. Go to
4. Adjust the intensity.
