By default, the camera is set to Auto Night Vision. Here is how Auto Night Vision works:

When the surrounding environment is dark, the camera will automatically switch to night mode.
In night mode, the camera uses its IR LED to emit infrared light and it switches to the image coming from the IR LED, instead of the image coming from nature light.
The image coming from IR LED is black and white. This is common for all the home security cameras, infrared binoculars etc.
When the surrounding environment is bright enough, the camera will automatically switch to normal mode or "day mode". It will shows the image coming from natural light.

Tips: In night vision mode, make sure that there are NO objects or surfaces too close to the lens to avoid that the infrared rays are blocked or reflected. Blocked or reflected IR can impact the quality of the image

You can turn on/off Night Vision setting, as below:

Open KINETCAM App >> Tap Video Window >> Tap "IR Light" >> Choose "Automatic night vision" or "Turn off night vision".
