Advanced Service configuration 
Advanced service configuration is intended to provide more sophisticated functions which 
are required by sophisticated users. Thus, if you are not familiar with or not good at 
advanced features, we recommend you to read this guide carefully and consult with your 
local vendor to get more close information about these features. 
 
Advanced service can be categorized into Buffering service and None buffering 
service
 depending on whether server stores pre/post alarm video in the system memory. 
 
Buffering service means that the server can store pre/post alarm image in the system 
memory and send stored image through FTP or e-mail or allow user to view stored image 
inside of memory.  With this feature user can get pre/post alarm image through e-mail or 
FTP without missing any video before and after the event or playback stored Alarm 
buffered image by connecting the server.
 
 
None buffering service means that Advance service will be done without image 
buffering inside of the memory. FTP(Periodic), Sensor notification service and Alarm 
output device control can be provided as a none buffering service option. 
 
Buffering Service 
Following services can be done by image buffering services. 
e-mail : 
Up to 10 frame of Pre/post alarm image can be sent when there is event is 
occurred. 
FTP (Rising or Falling edge) : Up to 256 frames of pre/post alarm image per video 
channel can be sent to ftp server when the event is occurred
Alarm buffering service :

user can playback stored image through web browser.
