After some ridiculous quotes from local companies I thought I would see what I could find on the net.  I am looking for a DVR unit and 3 cameras. 
  
I would like a stand alone unit since they're supposed to be more stable.  I need to be able to go back and review footage for 3 days at the longest.  I think a CDR would be sufficient since I won't have a need to backup to a CD very often.  Reliability and function are very important to me.  I want to be able to remotely access real time and playback too. 
  
I need three cameras.  One camera I'm hoping to position above a platform that is 6ft x 6ft.  The platform is two feet off the ground and the ceilings are 12ft high.  I also need audio for this camera. 
  
Other camera will cover a hallway that is approx. 6' x 40' long. 
  
Last camera will cover the main area.  The area is approx 150' x 150'.  I just need general coverage for this area.  I don't need it to zoom in.  The camera over the platform is the most important to me. 
  
I don't really know much at this time.  I've started to read on this forum to get a general idea of what's out there. 
  
I need to purchase everything within the next two weeks so any help would be appreciated. 
  
Thanks!
