EL1551U
Overview
Extend high-speed IP connectivity over your existing two‑wire infrastructure to modernize security and surveillance networks without disruptive re‑cabling. The Nitek EL1551U IP Transmitter-Receiver System converts any ordinary pair of wires into a 100Mbps Ethernet link, delivering reliable connectivity up to 460 meters (1500 feet). Its transparent, plug-and-play operation requires no setup, IP changes or special drivers—simply connect your switch and IP camera or monitoring device and begin communicating.
Designed for security integrators and network operators, the EL1551U supports 10/100 Ethernet and megapixel camera traffic while minimizing installation time and cost. Power is supplied from the receiver to the transmitter, and an optional PoE injector can feed non-PoE switches, simplifying power distribution to remote devices. LED indicators provide clear link, speed and power status for rapid troubleshooting in the field.
Ideal for upgrading analog UTP video baluns to IP cameras or extending networked sensors in transportation and industrial environments, the Nitek EL1551U is a practical network extender for surveillance, monitoring and access control projects. Deploy it to accelerate IP migrations and keep your security infrastructure connected.
