  • How wiring under long distance

    • Answer:

      The cable length should not be over 100m between the IPC and the next switch if over 100 meter, here are 3 solutions A: if the actual distance is between 200~300m, you can consider to use multiple switch series way, but in this way interference is a lot , so the use of up to 4 with good quality switch and switch between each other should not exceed 100m, the cost is low but the effect is not good. B: if the distance is more than 300m, it is recommended to use optical fiber and optical transceiver. This method is far from distance, stable transmission and low cost. C: if the distance between the monitoring points is remote and inconvenient to be wired, wireless mode can be considered.
