I want to connect 300 webcams into a single cohesive network.
How do I ask the right questions in order to know what other questions I need to ask in order to know what I will actually need to do ?
My first attempt at searching for this (Google, Bing, Yahoo, DuckDuckGo) produced the sadly predictable results: everybody and their brother has this ready to go for a zillion bucks.
That obviously isn't going to work, so, what questions do I need to ask next ?
By the way, if there's a discussion group or message board here on CodeProject where this post better belongs, point me to it.

Is this for a new adult site startup?  Must be expecting a lot of business.
Have you ever just looked at someone and knew the wheel was turning but the hamster was dead?
Trying to understand the behavior of some people is like trying to smell the color 9.
I'm not crazy, my reality is just different than yours!

hehe... first thing I thought of, too!! Perhaps this says more about us than the OP!!

Are you saying I'm warped?
I like that!

You're starting to know me! Ok what do you want to keep quiet?

Surely he would be better using wireless webcams?

I have no idea - but I guess it depends what you want to do with them and how widely located they will be.
I'd go down the Raspberry Pi (or similar) route - so you can network the PIs and capture the video - or stream it, or whatever.
Bandwidth and storage would be your only problems then.

Okay, the facility in question has 8 buildings, and I think those 8 buildings have 32 hallways, when you add them all up.
Along with the hallways, there are stairwells.
Along with the general hallways and stairwells, we want to watch about 150 to 200 doors; but we want to watch them in a limited fashion; i.e., when the door is closed, we want to stay uninformed.
Outside the buildings, we have, I'm guessing, 200 to 400 parking spaces.
About half of them are covered parking.
From looking at pictures from outer space, I guesstimate between 2 and 5 acres of sidewalks and lawns between the buildings. That's a total guess with no science behind it at all.
The first goal is to be able to document the cars that come onto the facility, and where the people go; e.g., to have a video record that the person in car X went into building Y and entered door Z.
There are other goals as well; e.g., the place had physical property damage recently, and it was clearly malicious. Nobody had a clue until the next morning. The perpetrator is walking around free and clear today; completely unidentified.

Have you tried googling DIY[?]
Otherwise Popular Mechanics might have the solution or C|Net seems legit

Does each of them have an individual static ip?

At this stage, that question remains.
At the moment, I see no need for them to have a static IP address.

Why don't you just email one of the companies e.g. y3k.com
Depending on what cameras you want, e.g. D1, 720-HD or 1080-FullHD, you could use a number of IP CCTV NVRs and split into clusters of 25 cameras. This would give you higher resilience to single point failure.
Have a look at the IP offerings on the site I listed. I am sure if you went back for an official quote from them for a large system there would be a huge discount.
Suppose depends on your budget, and how effective you want the system to be.

Side by side comparison of 2 identical hardware with Android and Windows Phone
http://www.engadget.com/2014/08/27/htc-one-m8-windows-review/[^]
They say the Windows Phone does perform marginally slower in some cases. Isn't Windows Phone allegedly in C++ and Android in Java? How come? Listening to MSDN one will believe Microsoft is obsessed with performance? How come it does so bad!
Maybe C++ isn't that good? C# isn't that fast? Java isn't that bad?!
(though I kind of try to forget my long past life as a Java developer, so maybe .. I should leave it at that...)

Interesting read and piece of the puzzle! Thanks!
Hey, more pressure to improve .NET Native!

I also wanted to add this, but took me time to find: http://www.infoq.com/news/2014/07/ahead-of-time-compiler-os[^]...
This method will remove the JVM and will tun your code on pure *nix...
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

I think I found in the article the thing you're referring to:
engadget.com wrote: Games run smoothly with few to no frame skips, but the same titles on Android were consistently more fluid.
Or you know, it could be due to the implementation of the actual games. The other things does not make sense, like this one:
engadget.com wrote: Android version is a little faster when loading apps and multitasking, primarily due to the time-wasting animations scattered throughout the Windows Phone OS

Yes you found them! Now what?! 
Ok, it does say it's kind of minimal. But they make a list of little things which adds up!
While they might be biased against Windows Phone, I would have expected these particular little things to be good and in favor of Windows Phone! Turns out I was wrong!

You may have missed one important fact - well written code executes faster irrespective of the language.
Some good tight Java will outperform floppy C++. Also remember that Java uses compile ahead, so once the class and method is loaded it is compiled, so the real performance hit is skewed towards start-up and goes down during run-time.
