Hey, I have a GV-650B and I am trying to get text overlay via TCP/IP. 
  
According to Wireshark, AlohaSPY is enabled and is seemingly transmitting to the NVR. How do I read the Aloha spy data? 
  
Right now the terminals are configured with unique ports (4001,4002,4003...) and the IP points to the NVR. 
  
Does anyone have insight into this? Thanks.
