Through the Eye, thriller sequence, tension analysis

Throughout the first sequence of 'Through the Eye', they use non-diagetic eerie music to create a creepy atmosphere to the audience and to create tension which will build up to shock the audience at the end. They also used diagetic noise to set the scene of the everyday life. It also makes you feel like you are there with the character, seeing from his point of view, which later on builds tension because the audience feel like they can almost do something about what the man is missing, but they cant which will frustrate, because you are seeing what you can see he's not.
This occurs when the man has a quick scan of a few of the screens but then he picks up his newspaper and isn't actually paying attention to his job and we as the audience know he is going to miss something when not paying attention.

We also see one of the screens behind him has something going on, both of the main characters, in one of these screens, have some red on them self, which firstly, makes the character easily identifiable and also comes with the connotations that he is potentially dangerous or a threat to the near future. The fact that the screen is behind him is reinforcing the fact that the man, who is meant to be paying attention to these screens, is unaware of what is going on and is going to miss out on something that we can see.

When they are doing a close up of four of the surveillance cameras, it makes the audience look for something, like they are trying to pre-empt the ending because they know something bad is going to happen because we are trying to look again for what the man is missing. Then the camera begins to zoom into a particular screen out of the four which makes us think that as we cant already see something in the screen that we are going to get a shock for what we are about to see, which builds tension. In fact this is just the camera tricking you into thinking that your going to get a shock so your guard is down, so you get more of a shock when the girl is taken/killed.
