Five Nights at Freddy's 3 Map and Cameras

I wanted to go more in detail about Five Nights at Freddy's 3's map and cameras. Lets start with the map.  If you don't know what it looks like this.

It doesn't look like much right now but I will show more about it in this blog. There are 10 cameras in this one as it seems from the trailer and on Steam Greenlight. But in the elements of Scott's website it says "CAM15". Where are the other 5 cameras? I think I know where.

If you brighten the picture it looks like this.

These blue and grey lines appear. What are these lines? I have two theories that they might be. One thing they could be is vents that the animatronic (aka "Golden Bonnie") could go though. What backs this up is that on Steam Greenlight there is a image with the words "ventilation" and we don't know what we would use the vents for.

 Another thing it could be is serest tunnels since this is a horror attraction. the tunnels would be use by the people who work there to scare the customers but in this case the animatronic would use them to get around without being seen. There isn't much in the trailer or in Steam Greenlight that supports this idea. Lets go to the cameras. There is one thing that I noticed with one of the images on Steam Greenlight. 

Its kinda hard to see but there is a blue button on the top right corner that says "Click". What might this button do? That might bring you to another camera in the vents or tunnels or whatever the blue and grey lines are. Another thing it might do is turn on/off the light in the back of the room. What supports that idea about being a light switch is in another image on Steam Greenlight there is another light with the same button but it's a different camera.

While we are on the topic of this image I have one thing to point out. There are () around that part of the map in this image. I think this might be thing to tell you about the "audio devices' that was shown in one of the images I showed before.

There is one thing I also noticed while looking at these images. There are dots in the bottom left corner on the cameras. I don't know what these dots could mean and I haven't found any theories about what these dots could be. In one of the images of the cameras there are 3 dots and in another one there is only 2 dots.

I said this in a my last blog so I'm not going to put the images again but if you flip the map image upside down it looks like Scott's profile picture (Which its a character in a game he made called "There is no pause button"). This blog is getting long so I have a question that I want you guys to answer in the comments. What is the arrow on the top of the map?

Its like this in every image with the map.
