A true plug-and-play solution
for connecting and powering
IP cameras over legacy
coaxial cabling

The HIGHWIRE Powerstar product family offers reliable power delivery
and long-range extension even over low-grade coaxial cable and now
enables direct replacement of existing analogue video encoders to
allow cost-effective upgrade to IP cameras

Existing Video Encoders

Many CCTV installations made the first
step to IP video by using analogue
video encoders to digitise their existing
analogue cameras and stream IP video
onto their network. This allowed the
analogue cameras running over
existing coaxial cables to be used
with modern network video recorders
(NVRs) and to be streamed anywhere
on the network (to a video wall,
operator screen or display monitor
for example). Video encoders were
frequently used to get the video onto a
network at the most convenient point
thus avoiding having to run coax cable
very long distances all the way to the

equipment room end. Digitising and
networking the video also added some
flexibility to the system in terms of how
the video data was routed and used,
and indeed this is part of the power
of IP Video systems.

Legacy Video Encoders

Existing video encoders come in many
forms, but by far the most common is
the stand-alone four-channel encoder,
as manufactured by hundreds of
different companies around the world.
All have very similar characteristics:
Four BNC connections for the coax
cables, a network connection and a
power connection.

PTZ Control/Audio
Some video encoders also had
RS232 or RS485 ports for controlling
analogue PTZ cameras. Of course,
such serial connections are not
required for IP PTZ cameras, as all
control signals go through the Ethernet
network connection along with the
digital video. Likewise, some analogue
encoders had audio I/O, but again,
separate audio connections are not
required for IP cameras, as the signals
are incorporated into the network data
and recorded by the NVR.

HIGHWIRE Powerstar Base 4 directly
replaces the analogue encoder unit.

Direct Encoder Replacement

HIGHWIRE Powerstar Base 4 builds
on the market-leading HIGHWIRE
range of Ethernet-over-coax (EOC)
adaptors from Veracity, and is
designed as a direct replacement for
legacy analogue video encoders.

EOC Base and Camera Units

In Diagram 2 above, the legacy
analogue encoder is replaced by a
HIGHWIRE Base 4 unit and the coax
cables are connected to four separate
single-channel HIGHWIRE Powerstar
Camera adaptors. Note that Duo and
Quad Camera adaptors are also
available. The low-resolution, locally

powered analogue cameras are
replaced by high-resolution POE
powered IP cameras. A Gigabit
Ethernet uplink connection on the
HIGHWIRE Base 4 ensures there is no
network bandwidth limit on available
image quality and resolution.

Automatic connection

As soon as the power is supplied to
the Base 4 unit, a connection is
established automatically with the
Camera units, the IP cameras are
powered up and the camera IP
addresses will be available on the
network. The HIGHWIRE units require
no configuration, do not require IP

Recommended Power Supplies

There are two PSU options available
for HIGHWIRE Powerstar Base 4
units. They are 57V DC to provide the
maximum power and distance
possible within the POE standard.
(IEEE 802.8af and 802.3at)

The options provide 40W or 80W.
The 40W unit provides 10W per
channel over the coax on the Base 4
unit, which is sufficient for most static
IP cameras. The 80W unit provides
up to 20W per channel on Base 4.

POE-over-Coax™ Range

HIGHWIRE Powerstar delivers reliable
power at long range, even over low
grade CCS cable. No set-up is
required and the coax connection is
automatically established on power-up.

The table shows the range achievable
by cable type and camera wattage.
