That's the light overloading the camera's charged coupled device sensor. That's what usually happens when you point cameras at the bright light source. Point your cellphone camera at the Sun on a clear day and see what happens.
The only glitch here is in the minds of the people who want to feel special because they believe that they are in on some dark, nefarious secret. Matrix wasn't even a thing until the movie came out.

Yes. I did watch the whole video, and it's still the light overloading the camera's sensor and lens reflections, no matter how you invert it, zoom it, play it backward, stand on your head or jump on one foot while pulling your left ear while watching it.
Response to the Second Comment
Yes, it's called a lens flare. It's caused by the light bouncing around inside the a cheap camera lens, such as the one on a CCTV camera. Take you cell phone camera and point it near the Sun on a clear day. You will see the same thing.
Now, you take a look at this picture:
Notice that all the photographers have a big cylinder at the end of their lenses? Those are light baffles to stop the lens flares, not because these guys think that they make their cameras look cool. These photographers know infinitely more about light flares and overloading cameras' sensors than the joker who posted the video on which you hanging your whole perception of reality.
