Installation Guide
Model NV-EC1701 EoC Ethernet over Coax Transceiver
with PoE, PoE+, or High Power PoE
The NV-EC1701 transceivers provide transparent end-to-end 10-
baseT or 100-BaseT connectivity with auto detection and auto-
crossover. This means that IP cameras or other devices may be
installed at one end, and their data is transparently delivered to
the other end. Before installing, transceivers must be configured
per the instructions on page 3.
Long coax distances are supported, although local power may be
required for extended distances. See pages 7 - 9.
The NV-EC1701 supports TCP/IP, UDP, HTTP, Multi-cast, and other
standard protocols. This allows for the transmission of other
network traffic besides streaming video.
The NV-EC1701 is network transparent, and operates in virtually
every network environment, including support for Hybrid DVRs.
These DVRs have some BNC ports for analog cameras, and some
RJ45 ports for IP cameras. The RJ45 “video in” port is the con-
nection point for the NV-EC1701. See figure 2.
By deploying a Hybrid DVR, with its dedicated IP camera port(s),
the network is robust and secure, with none of the traffic, hack-
ing, or virus vulnerabilities associated with PC-like hardware on
an open LAN.
Depending on the Hybrid DVR, more than one camera may be
connected to its IP camera port. Check the Hybrid DVR manual for
details.
