pre alarm buffer size for respective camera can be done within this assigned memory. 
Note that Pre Alarm buffer for even Alarm buffering service can be done within this 
memory size. 
Thus, you need to be careful to assign memory for this service. The rest of memory after

Alarm Buffering Service size :  
To assign memory for Alarm buffering service to save pre/post alarm image in the

be done within the Pre-alarm Buffer size. Thus, you need to count in required pre 
alarm buffer for alarm buffering service and reserve enough space for this service in the  
Pre-alarm Buffer size.  
 

Pre alarm buffer size (Image Buffer Pool) means the number of images to be stored

Maximum Pre alarm buffer should be the half size of Memory capacity, since Pre
