How to benefit from IR light in low-light conditions using night mode
Your camera uses visible light to deliver color images during the day. As the available light diminishes, you can set the camera to
automatically shift to night mode, in which the camera uses both visible light and near-infrared light to deliver black-and-white
images. Since the camera uses more of the available light it can deliver brighter, more detailed, images.
1. Go to Settings > Image > Day and night, and make sure that the IR cut filter is set to Auto.
2. If using an accessory IR illuminator, enable Allow IR illumination and Synchronize IR illumination to use IR light when
night mode is activated.
