Do they think that somehow helps surveillance? Like do all the security people have better vision in that spectrum??

Well yeah one reason for red lighting is that it doesn't trigger your eyes switching from night vision to day vision, you can go into a red-lit room and walk out into the dark without any period of being blinded

The psychological reason for red light creeping you out is probably linked to that to an extent, it's the blue portion of white light that triggers your eyes to detect sunlight and tell you it's actually daytime now

That's why computers do the thing now where they filter out blue light at night to stop the screen giving you insomnia
