Vigitron's OmniiCopper Vi27004 4-port Ethernet and PoE Receiver brings new performance standards to the growing need for high-speed transmission of full bandwidth Ethernet and PoE power over extended distances of Single-Pair Wires. It operates in conjunction with Vi27000 transmitter over virtually any 2 conductor wires reliably. The Vi27004's unique transmission technology eliminates the potential for cross-talk resulting in the perfect solution for bundled cable runs used in many elevators and building communication systems. Its PoE performance conforms to IEEE 802.3af/at standards.PoE power can Pass-Through from a PoE source to eliminate the need for a local power supply at the camera location and increase system reliability.The Vi27004 is a 4-port receiver. Up to four Vi27004s can be placed within Vigitron's Vi5000R rackmount tray to create a 4, 8, 12, or 16-port rack-mount receiver solution. The Vi27004 can pass through up to 36W PoE power on each port compliant to IEEE802.3.at to power the connected IP camera. It is type-tested under NEMA-TS2 environmental standards for extended temperature operation between -30°C to +50°C. The Vi27000 series is the perfect solution for extended-distance data and power transmission for elevators, warehouses, parking lots, campuses, casinos, and many more. OmniiCopper Vi27000 series is MegaPixel Certified (MPC), the type tested to network packet performance standards, and major camera brand compatibility tested to assure you error-free and reliable operations. Installation cost savings, tested and proven design and performance go into making the Vi27000 series the perfect solution for building CCTV wiring.
