Need help designing a home cctv system

[Helen 0]

First off, let me apologise for lack of technical knowledge (I'm a total noob).

 

I wish to create a cctv system for my home, but am totally confused by it all.

 

I want the system to be 4 cameras (IR)which will be wired and I want video to be saved to a DVR.

 

So my question is....what items should be on my shopping list?

 

Thanks in advance

Helen
