Based on long distance data transmission switch system that supplies power with wide pressure of ethernet port

The utility model discloses a based on long distance data transmission switch system that supplies power with wide pressure of ethernet port, including direct current input module, DC DC module, distance control module, host system and network interface in light current construction, network wireless engineering, during the transmission of security protection surveillance video, can adopt this kind of support with the switch of ethernet power supply, reduce power wiring, utilize net twine transmission signal simultaneously, provide electric power for headend equipment, and when distance duringabove 100 meters, distance control 0 opens 250 meters modes, just can solve to be greater than 100 meters distance control 1 that can not communicate. Two switches of ON -OFF control circuit controlthrough the centre are paralleling model, and a distance control module and the 2nd distance control module mechanical control are parallelly connected, during toggle switch, open and close 250 meterstransfer mode simultaneous
