When there is sufficient light, the camera convertsautomatically from Night mode to Day mode.o On-activates IR mode (puts camera into monochrome/Night mode).o Off-deactivates IR mode (puts camera into color/Day mode).o Smart-Smart Mode enhances monochrome/Night mode stability when IRillumination is dominant and keeps the camera from switching between Dayand Night modes. In this mode, the IR Cut filter is on (i.e.monochrome/Night mode) when the IR LED illuminator also is activated.This prevents the camera from returning to color/Day mode.Press <√> to confirm the new setting.
