Migrate from existing analog cameras to IP using virtually any cable at almost any distance. The TBus IP and PoE transmission system from NVT allows installers to take advantage of the extended distance of PoE power and data distance benefits while using already installed analog camera network legacy cable. TBus, short for transmission bus, technology allows installers to approach their customer's IP migration with a different set of rules about distance, cable usage, topology, project timing and cost.
