Outdoor cam not taking videos at night

I have tried every trick listed in the help guide, but my outdoor CamPlus is not taking videos at night. It works fine during the day but does not work at night. I have the camera set by a small water supply that animals drink from. I know they are drinking at night. This night vision recording function used to work but now it does not. Any help in rectifying this situation would be greatly appreciated. Thank you.

Did you try changing the night vision from Auto to on at night, or turn off then to on. Maybe there is an issue with the auto function. Do all the IR lights work and are they turned on? You can turn to night vision to on during the day and see if the live view will change from color to back and white.
