Dear user, sorry for the inconvenience. If you want to open the camera night vision function, you can click on the upper right corner of the device details page, select settings, then find it and open it. Under normal circumstances, the camera will automatically switch to night vision mode in a dark light environment. At this time, the image is black and white. If your camera cannot enter night vision mode, please update the App to the latest vision and rebind the camera（Don’t forget to unbind it through the App, otherwise there may be the phenomenon）. If the problem still occurs, it may be that the hardware of the camera has malfunctioned. It is recommended that you contact the seller for after-sales processing. Thank you for your support. Note: Most cameras are designed to be forced to switch to color mode under strong light environment, because the strong light environment will burn the night vision module of the camera.
