1. SFGT-FD020VM-Product Introduction
 
  
 
The 3rd generation FDD two-way network video transmission system has achieved a more high speed data transfer since its upgraded high linearity mainboard, also the spectrum utilization and system capacity has been improved greatly.
 
Integrated with Ethernet port, the SFGT-FD020VM is suitable to connect any IP-based devices, like IP camera, computer, etc..to achieve microwave wireless IP video or other data transmission and communication. There is also with serial ports, two RJ45 network ports and PTT bidirectional voice intercom ports for remote wireless radio link,meanwhile a data port and a voice control port has been added on.
