HYBRID DVR CONSIDERATIONS
TRANSCEIVER-TO-TRANSCEIVER
HYBRID DVR ARCHITECTURE
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 up to 2,500 ft (750m) are supported, although local
power may be required for extended distances. See “High Power
Extended Distance Considerations” on page 7.
The NV-EC1701 supports all standard protocols, such as TCP/IP, UDP,
HTTP, etc. 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 connection 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, hacking, 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.
