Orbs & Missing Jewelry

I am staying out of state for the winter, and my house in Pennsylvania is empty. I set up Blink indoor cameras to monitor the house. For the last month or so, just about every night, multiple times per night, I get motion notifications and see a transparent orb floating in the room. In different videos, it floats left to right, right to left, up to down, down to up. Sometimes bouncing and sometimes hovering. The blinds are completely closed, so I have ruled out outside light. It appeared once in daylight, so I ruled out infrared.
In addition to that, on two occasions, jewelry that had been missing for a year suddenly appeared. I was in the kitchen and heard something metallic hit the floor. It was my husband’s wedding ring that had been missing for more than a year. It seemed to drop out of nowhere. The second occasion was a missing earring that one day appeared on the basement floor. That basement was vacuumed and mopped once a week, so no idea where it came from.
