In the instance you have reported it, this is quite rare and to be honest with you, this is the first occurrence of a capture like this I have seen of this type.
I think something like this would happen because I have actually seen it before and on more than one occasion. Wifi cameras can be a pain sometimes. Despite them being tied to a network via a WPA2 key, they can sometimes drop data packets into other streams unintentionally. As these are airborne data packets, they can originate from anywhere. It occurs because, when wireless signals are being transmitted or received simultaneously in a MIMO (Multiple-Input Multiple-Output) environment, the signals being transmitted by the various antennae are multiplexed by using different spaces within the same spectral channel. These spaces are known as spatial streams. Sometimes these spatial streams become identical within the spectral channel simply through mathematical odds - at some point, the random multiplex from two separate sources
will match and crossfeed.
And no, unfortunately, we can't re-create it. Not outside of a lab with specialist equipment, anyway......
A person after my own heart
Don't forget the
block universe theory on that list...........
I do not believe that there are any specific triggers as far as portals go for entities coming in or out. They are pretty much free to come and go as they wish, but I believe that most are drawn by energies - our bodily energies, emotional energies and the energy of interaction with other spiritual entities (what I referred to as becoming a
spiritual beacon). What they are - we do not exactly know. Some believe they are tears within the fabric of space and time and can link our plane with other dimensions, or different planes of existence within our own. A bit like how a wormhole theoretically connects two points in space that we can pass through.
As always with the paranormal, there are more questions than answers
