Ghost Caught on Security Camera

We started hearing things in our attic so we decided to put one of our wireless cameras up there which is only triggered to record when movement is detected. We had several videos with moths and dust flying around, none of them looked anything like the orb looking thing that is seen in this video. Even though it is hard to see, this is a few videos taken on the same night all edited together. Whether you are skeptic or not, it is strange to say the least.
