Cameras for video assistant referee
systems (VAR) - What should they be like? cont'd...
The most convenient way to control
the cameras is to do it from the server
software. No additional equipment
is required, the operator can quickly
configure
the
camera
and
unlike
external consoles, settings cannot be
lost.
The same Ethernet cable can also be
used to power the camera using Power
over Ethernet technology (PoE). This
not only avoids additional cabling, but
is also useful for mobile VAR systems
because there may not be a standard
power source near the camera.
The availability of a
Power Bank is also an
advantage.
If cameras can operate in
sync mode, they are ideal
for the video-refereeing
applications.
The sport specifics
For some sports there
are additional camera
requirements. So, when
working with water sports
cameras should allow
the installation of a polarizing filter.
Otherwise, the light glares from the
water surface will complicate the
process. The same applies to ice
hockey.
PTZ cameras
PTZ cameras have a controllable lens
and are often waterproof. Pan, tilt and
zoom adjustments of these cameras
can be accidentally changed (let's not
exclude the human factor).
Despite being more expensive
than cameras without PT capability,
PTZ cameras are suitable for videorefereeing
(e.g. Panasonic AW-HE42).
Super Slow Motion
cameras usage
Everything mentioned earlier applies
to the standard speed cameras.
However, SSM cameras, which provide
more frames per second, require
a more powerful server with more
recording channels, better processor
and larger storage capacity.
The 2x cameras use 2 SDI recording
channels or require specialized
interfaces such as HDMI
2.0, which does not
transmit the signal over
long distances.
A sensible idea is to use
SSM cameras in certain
areas, for example, on
the " blue lines " in hockey
to analyze the " offside "
position. But it should
be understood that for
situations in which the
position of objects at a
particular point in time
plays a key role, only synchronous with
each other SSM cameras should be
used without considering the standard
cameras.
Let's review an offside
situation
in soccer. While a normal camera
generates one frame, the SSM camera
generates two frames.
On the normal camera we will see
the kick, and the first frame from the
SSM camera will show no offside but
the second frame will show the player
in offside position. Which frame should
we believe? The referee should not
make this choice, everything must be
accurate.
For such situations you need an
elaborate
set
cameras.
As an example of cameras specially
designed to work in VAR systems,
you might consider the slomo.tv
mini-II-VR-CAM.
It provides Cloud Genlock, built-in
10x/3x Zoom lens, PoE or micro-USB;
control via Ethernet of Zoom, Focus,
IRIS, Exposition & Color Correction.
