Schools adhering to the "quality education resources sharing practices, promote education equalization process" educational philosophy, give full play to the advantages of the network, sharing of resources. Schools through the "one on one, face to face," the network video synchronization teaching for the city hundreds of thousands of schoolchildren offers advanced real-time interactive online learning platform. 7 8km audio transmitter phone connected WiFi (provided that in the same look and PC), running Android DroidCamX phone. At this time, the software will automatically open a port to send video data, record this port and IP address (as shown in red characters). coincidence is, just with our international sales department to the door, where there are just a Tsinghua boy. He also often stay late into the night in the company, but the difference is that he is always there to see a basketball game, playing the game; while Fan grade boys are out there desperately overtime, to learn. The key difference is that: When a person where people play games when it opened bright fluorescent entire office 200, Fan grade boy was founded 10 years for voluntary overtime has been the only one to stick with the lamp employees.
