BINARY DOMAIN

The videos above are excellent, a couple of things to add though. The SECURITY-COM doesn't have to be collected all in one play through. Once it's been found you will no longer be able to see it in the game if you revisit the location, so if you can't see it you probably already have it.
Once you have completed the game once and unlocked chapter select you can see where you are missing SECURITY-COM and select not only the chapter, but the specific part of the chapter you are missing it from.

I managed to find a guy whose posted some walkthroughs on Youtube, remember to give the vids a thumbs up :D (Watch your ears, they're a little loud).

Each one you find is done for all play-throughs, and if you're missing some and don't know which ones, when you unlock chapter select mode it will display on each segment how many you have.
