PTZ, or not PTZ? -
It needn't be a tragedy
P
With Clive Mumby, Sales Manager, Shotoku UK.
TZ systems today are a long way
from the early generation systems
which suffered limitations in picture
quality, optical performance, and onair
movement capability. Today, PTZ
cameras from several leading suppliers
produce 4K UHD image quality, have
significant optical zoom capabilities
(mixed with digital zoom) and offer a
wide range of connectivity options.
So, when considering a remote
camera system there is an obvious
question: PTZ or full-broadcast
camera/lens? Shotoku doesn't make
PTZ systems, we design and build
high-end robotic camera systems
of all shapes and sizes for use with
third-party broadcast cameras and
lenses. We do, however, control a wide
range of other vendors' PTZ heads.
Customers are free to adopt a single
PTZ vendor,
or
and
multiple,
often
all under
the control of the advanced Shotoku
systems
in combination
with high-end broadcast systems on
Shotoku PT heads and pedestals. We
therefore have a good insight into the
pros and cons of each approach. We
know when PTZs make perfect sense,
and when they don't.
PTZ solutions will always be cheaper
than full broadcast cameras/lenses
and PT heads. It stands to reason that
a CCD chip, however advanced, in a
plastic enclosure with built-in optics
and
servo
motors
will
always
be
cheaper than a precision engineered,
hand-built PT head supporting a fullfeature
camera with a zoom lens.
Like a portable radio compared to a
separate HiFi receiver, amplifier and
surround sound system. So, if low cost
is the one and only consideration there
is no question that a PTZ solution will
be best.
PTZ solutions also give a very
convenient one-stop-shop and can
simplify the purchase and installation
of
multiple camera systems. These
types of systems have long been used
in live performance events where ease
of rigging and the small 'footprint'
of supporting technology
is a significant advantage.
In a fixed, permanent,
installation like a TV news
studio or large parliament
where these one-off
installation challenges
Shotoku has been installing these systems for decades in high profile national parliaments
including in the USA, Canada, UK, European Union, Korea, Singapore
and countless others around the world
are less significant, the use of best-ofbreed
broadcast solutions will always
give higher performance and control
flexibility in both imaging and robotics
performance.
Possibly even more important than
the CCD imaging capabilities, are the
optical characteristics of the lens. Full
broadcast lenses, even compact ENG
style, contain numerous opticallyperfect
glass elements, carefully
arranged to give perfect images and
smooth transitions across a very wide
range of zoom angle - with no impact
on the image quality and minimal
effect on exposure. These physically
larger elements are essential in
providing this level of performance,
something impossible in the tighter
confines
of
solutions.
Finally, the subject dear
to Shotoku's heart, is
the robotic control and
on-air movement. PTZs
have
improved
Shotoku's TG-27 remote pan and tilt head
a
lot
in
this area too, but when
it comes to ultra-smooth,
repeatable, fully-synchronised
the
integrated
PTZ
PTZF movements that high-end TV
studio and parliamentary systems
require, it is not possible to match the
performance of a solidly-constructed,
perfectly
balanced
matches
the
motor/gearbox
system found in a Shotoku PT head.
The weight and balance of these
systems
camera
load
perfectly at all speeds and acceleration
and deceleration demands, regardless
of payload. The exceptional build
quality also ensures that the high
performance will remain day-afterday,
year-after-year, in many realworld
cases for decades of intensive
use.
So, the final choice depends on
common factors like cost and longterm
performance,
the
good news
is Shotoku allows customers to mixand-match
the best solution for the
application,
without
compromising
cost effectiveness, ease of use, or
operational flexibility.
The best of both worlds!
