There
are many options which together can meet all CCTV requirements.
Brief descriptions are provided below and please click
Specifications
for details.
Automatic
power and frequency control is used to avoid any adjustment
during installation and to provide high video quality
in demanding environments. The links operate between -20C
to +60C, but options are available for -40C to +70C, including
sunlight at 1 kW / sq m. The equipment complies with the
EMC specification EN 300 339 for both emission and susceptibility.
Also, unless otherwise stated they are compliant with
the ETSI specification EN 300 632, or the equivalent UK
specification.
Split
Configuration
A
long range equipment which comprises two units at either
end; the Transceiver and the Modulator or Demodulator
Base Unit. The range in all weathers is 25 km at 31 GHz
and 80 km or more at 5 GHz. One or two video channels
together with a bi-directional data can be transmitted.
Compact
All
the electronics is contained in a single 40 x 20 x 20
cm enclosure at each end. The short range units operate
at 58 GHz and transmit a video and bi-directional data
at ranges of 600 metres to 1.2 km. The long range versions
operate at 31 GHz and can transmit up to to 10 km. Two
video and data options are also available.
SuperCompact
The
SuperCompact is just 30 x 18 x 9 cm. It provides all
the functionality of the Compact as well as in-built
signal strength indicators for initial alignment and
remote fault monitoring.
Unlicenced
Links
The
SL58 is a low cost single video and data equipment that
operates in the unlicenced 5.8 GHz band. It has frequency
and data switches and an in-built signal strength meter
which makes it ideal for transportable applications.
Like all unlicenced equipment, it is prone to interference,
but suppression techniques have been incorporated to
reduce this to a minimum.
Mobile
Links
Our
mobile,
non line of sight, systems use Orthogonal Frequency Division
Multiplex compliant with the international DVB-T standard
for terrestrial digital broadcast. The equipment can be
configured for many applications, including man portable
and vehicle mounted. Different frequency converters are
available for operation from 1 to 24 GHz. Man pack and
vehicle mounted versions are described in Mobile
