Wired stick up cam night vision won't shut off

The night vision on my wired cam is always on. It shows as a bright white light from the battery cam off the back of the house that faces it. The two battery cams that I have when filming at night the infrared will light up as bright white light then turn off after filming as seen by this wired cam. The wired doesn’t shut off all night long. Does anyone know why the night vision on this cam not shutting off? It used to.
