Flood cam Sleep mode

I would like to make my flood light “go to sleep” without a scheduled setting. We have lights in our back yard for the hot tub and would like to just have those LEDs come on without the flood light picking up the dog or people in the yard and turning the lights on. I don’t want to schedule it off for everynight for 4 hour window just in case someone wants to get in the hot tub. Any suggestions?
