So too, were the photos of orbs I was getting on my still cameras and the noises I was hearing on my stationary video cameras from somewhere else in the room. So I decided that I would employ multiple cameras that took photos and video simultaneously in my investigations. The double still camera has proved invaluable in dispelling the orb phenomena. The multi video cameras makes it easy to cover an entire room, if placed in the center of the room. This way nothing can happen in the room without being captured. Yes, it can get a little pricey but the benefits have been worth it.

If you get an orb in one and not the other then you know it's dust, moisture etc. The same piece of dust or whatever can't be in front of both lenses at the same exact time

I also got tired of someone saying, " What was that behind you? " when I was taking photos. This can help with that also. All still cameras are linked by a common shutter release. I also usually use a mono-pod for the still cameras to get around easier.
