Spotlight Cam Reports Motion in Bursts of Three or More

Hi!I have had a spotlight cam on our back deck for a couple of years now. Last summer I bought the solar charger so I don't have to keep charging the battery. It's been working perfectly until a couple of months ago. I was getting alerts that the battery was dead. I thought maybe it was from the cold so I charged it. Then I'm getting these weird bursts of notifications every time the camera picks up motion. I will get one, then another, then another and sometimes more very quickly all in a row. I find myself snoozing it just so my watch isn't constantly bugging me. Is my camera broken? Is it the battery? It's been working flawlessly up to this point.Thanks for any help!
