Night lighting (infrared) became dim immediately and never returned to full brightness

I was reviewing the still shots of my doorbell camera (2020 release) and the night vision dropped in brightness. The infrared is still on but no where near as bright. Using my iphone I can see the light locations as the phone camera can see infrared. Faulty doorbell? Everything else seems fine. The camera seems to be filming where it's looking at what a person might see. My landscaping lights show color (no, it's not the, display color option, that some cameras can do with night vision) and everything is much darker. The infrared is still on to some extent because my door is still lit by the lighting just a bit. screen grabs attached. As a new member I can only attach one. This is the dark image. The one that's bright lights up the entire yard but I can't attach due to restrictions of this site.
