This problem is caused by the shortage and packet loss of Gbps. Our solution is to make the Gbps large enough. For example, the Gbps for traditional 4 port POE switch is just 800Mbps, while the Gbps for ONV HD used 4 port POE switch is 1.6Gbps. Besides, to solve the packet loss problem in data transmission, ONV imports the Industrial Ethernet HSR Zero-packet loss technology, which perfectly works out a solution for this puzzle.
