Rain sets off alert

Normally, rain doesn’t set off my motion detection. However, if something else normal sets it off while it’s raining out then afterwards the rain will set off the motion detection. It goes off literally every minute after that until the rain lightens up. Our area has a lot of wildlife and stray cats that naturally set off the motion detection and it rains in my area quite a bit so this is really troublesome.
We’ve only had the cameras set up for a few months and we’ve already had to recharge the backyard camera that’s supposed to last a year on battery life. I’ve woken up to 99+ alerts. I’ve tried changing active zones and turning the sensitivity down super low but nothing seems to be doing the trick. Does anyone else have this issue or can offer a solution?
