Line up


VPLC-CORE100/C is a communication module with the function to superimpose signals on the coaxial cable and existing communication line. The system building is possible without new setting up communication wiring construction in case of replacing an IP security camera from an analogue security camera by this product.


VPLC-CORE100/M is a communication module that has a various signal LC-CORE100/C.
With this product, building a system without setting up new communication wiring construction is possible for controlling of lighting, air condition, measuring of power consumption and various sensors.
Up to 10 steps of hopping are possible, expanding the coverage of network area in a building.
It contributes to the creation of new service in the field of IoT by enabling various EMS and equipment monitoring of controlling BA and FA.
