Hello Gentlemen, 
  
I am switching from the Analog world of surveillance to the exciting field of IP. I am very impressed with the knowledge that the members possess here, so I joined the forum to help me get started. 
  
What are some of the top brands/manufacturers around? I heard about Dahua, Axis, Mobotix etc.. What do you recommend and what do you use? 
  
I am a little bit confused about the pricing on some NVR systems, some NVR charges license per channel, while others charges per unit? Why is that?  
What brands/models tend to charge per channel? What are the advantages of doing so? 
  
I have questions regarding cameras too, but I would like to do it one step at a time. 
  
Thank you very much in advance, 
J.
