I posted this in system but it just never showed up. 
  
I would like advise on which dvr and cameras to purchase.  I want to monitor my vacation home for any vandalism or thievery and be able to use the recording to give to law enforcement.  So I figure I need a dvr that can record high frames/minute.  I could be away a month at a time so I would need good motion recording to keep from filling up 30 days of nothing.  I need 24 hour a day so 60-100ft of night vision would be needed. 
  
I am on a budget but only need 2 cameras so I was hoping to get a dvr and 2 cameras for $700 or less.  I have found some likely candidates but not sure of the quality. 
  
Here is what I found for a dvr on amazon:  
4CH CPD560 / AVC760 Real time Pentaplex Network DVR 
  
or  
  
Gadspot GS1800 (4-CH) on gadspot dot com 
  
and for cameras,  
  
Lorex High Resolution Day/Night Camera with 30 LEDs (Color) on amazon 
  
or  
  
GS232B    Day & Night Outdoor CCD Camera (Waterproof) 
on gadspot dot com 
  
I appreciate any help you can provide. 
  
Thanks, 
Rick
