& ftp and Alarm buffering service 
B. Pre alarm buffer size : Once memory allocation is done, assign Pre alarm buffer 
size (Pre alarm image buffer pool)
 to be used for e-mail, FTP and Alarm buffering 
services. Any pre alarm buffer for respective e-mail, ftp and Alarm buffering services can 
be done within Pre alarm buffer size. 
C. Pre/Post alarm for respective service : Once Pre Alarm Buffer Size is decided, go 
to respective e-mail, ftp and alarm buffering service menu and configure the options.

1.1.1 
System Memory allocation  
The number of Pre/Post alarm image for advanced services should be pre-defined to 
effectively use the limited memory capacity. 
 
 
Total Buffer size : 
This shows the maxim system memory for alarm buffering services. 
The number of maximum total buffer frame for respective services can be decided by 
following formula 
Total buffer size / file size = number of total buffer frame 
e.g) 500 KB / 10KB = 500 frames which is possible total buffer size. 
 
Total Pre-alarm Buffer size : 
This is to assign memory space for the services that Pre Alarm video buffer is required 
such as e-mail and FTP (Edge service) and Alarm buffering service. Once it is configured,
