Hi, 
  I'd tried to search for this but cannot find the exact answer. 
  I'd installed Gv-1240 (8.5.9) and it's will create WebTemp folder automatically. Currently I take the static image in jpg (inside webtemp folder) to ftp server using filezilla. I tried to search for interval setting on the DVR which the jpg were snap but no luck. Currently the jpg will change(overwrite) every 1 minutes I guess and I want to change it to every 5 or 10 sec. 
  
Does anyone have any idea to that. 
  
Thanks in advance.
