Human movement stirs up dust.
Orbs of light on security camera.
Nearly because we are open minded and regard each new instance of an orb as a separate case.
I note that the camera is in b w for low light level i don t know for sure if the ir filter is in place but i d kinda bet it is.
If that s true it may be that these orbs are just reflecting more ir than visible light making them stand out more.
So orbs are not always spiritual but they certainly can be.
Orbs most often appear on camera when a piece of airborne dust an insect or a water droplet is close to the camera outside of the depth of field and the flash source is no more than a few.
Light simply bounces off our camera to something spiritual or physical whose energy is dense enough to bend or reflect the light back to the camera making it possible to capture photographically.
When we say orb in fact what we re referring to is a physics equation.
This explains nearly every orb photo you will ever see.
