I am wanting to setup a 4 camera system that can be expanded to at least 10 cameras.  If possible I would like to keep it under $1500.  If needed I could start with only 2 cameras to help keep the price down.  Image quality needs to be good enough to be used to identify unknown people.   
  
2 cameras will be outside under a patio.  1 camera will be inside and the last will be outside exposed to the weather.  
  
I would prefer PoE cameras as power is not near some of the camera locations. 
  
I can have the patio lights on a dusk to dawn sensor or a motion sensor depends on what would work better.  The inside camera I would like to work in the dark but I could also put the lights on a motion sensor if it would help.   
  
The NVR can be either standalone or computer based but I will need to buy/build a computer for it.   
  
Any recommendations on cameras and NVR?  Thank you
