I am not sure if its standalone DVR device.  
But I think its a standalone DVR system most probably.  
  
And i think there can (must) be keep a file for keep setup parameters.  
  
Now i want to show an example.  
Some DVR CARD systems are saving setup parameters in a DVR.INI file 
and you can access this file like that http://xxx.xxx.xxx.xxx/dvr.ini 
  
Look the picture.  
  
 
  
  
My purpose is remote access the setup file of standalone dvr device which using web application manager web interface.  (without setup interface) 
  
I hope i told truely (Sorry for my poor english)
