Indoor camera detecting motion every couple minutes

I have received around 7 notifications in the last hour that there has been motion detected from my indoor camera. Every time I check the recording there is absolutely nothing in view, no animal nothing out the window, not even a reflection in the TV. I am at a loss at what to do other than just turn notifications off or motion detection off. I had this same problem with the doorbell camera a month or so ago, I ended up turning the motion detection off. I'm not sure how much long I will be staying with SimpliSafe with this issue continuing. I haven't gotten a hold of support yet today for the indoor camera, but SimpliSafe has not had the same quality in support the last couple of months. I have been a customer for over 3 years and never had a problem until the last few months.  What is the point of having the cameras at this point????
