Yes.
The cams are pumping out infrared light from the face of the cams. Anything that passes in front of the cam lens will be spotlighted by that IR light at very close range. Most of these are microscopic dust specs in the air current passing within mere millimeters of the lens. Others are nearly invisible flying insects in close proximity. They won’t be seen in daylight because the visible light source is not from the cam.
The voices however is hard to explain without a sample of the audio.
