SCP-XXXX stay in an inactive state

"stay" should be "stays", however I would suggest changing it to "remains"

Although, the amount of light needed lessens if someone or a viewed live recording with the ability to enhance vision in the dark look directly at SCP-XXXX.

This sentence has multiple issues:

Starting a sentence with a conjunction ("although") is bad grammar.

everything after and including the word "someone" reads weirdly. I would recommend rewording it to something like "…if SCP-XXXX is either viewed directly or viewed through a recording device capable of light enhancement."

it will flip to an upright position of 90 degrees

"it will flip to an upright position" is clear enough.

SCP-XXXX will stay like this

Again, I would suggest "SCP-XXXX will remain in this state"

SCP-XXXX will proceed to follow the viewer directly from their line of sight at a rate of 1 meter every 3 seconds.

Another weird sentence. If I'm interpreting this correctly, you mean "SCP-XXXX will follow the viewers line of sight, travelling at 0.33ms-1"

When it is approaching a camera, it will typically be distorted through visual blurs and colour distortions.

This sentence is not necessary and could be shown by editing the image. I know a few strange tricks to make the effect you have described if you would like me to.

The collapsible needs some formatting.
