Information about the wireless transmission of video signals and audio
signals by using transmitting units and receiving units of the AV-3000
and AV-5800 series!
The main difference of these two systems is the transmission range
of 2.4 GHz for the AV-3000 system and 5.8 GHz at the AV-5800
system.
The video/audio transmission system of the AV-3000 series is both
suitable for industrial and commercial applications as well as for pri-
vate applications. It operates in the frequency range of
2.400-2.4835GHz with a transmitting power of 10 mW. The fre-
quency range is divided into 5 channels, 3 of which can be used
simultaneously f
or parallel operation (channels 1, 3, and 5).
At a suitable antenna configuration, even all 5 channels can be used
for parallel operation.
Due to the high sensitivity and the selectivity of the channels in-
creased by approx. 20 dB of the receiving units, this system allows to
obtain the same or an even better picture quality and transmission
range at a transmitting power of 10 mW than systems with a trans-
mitting power above that!
The system is suitable for the transmission of standard video sig-
nals in the formats: PAL, NTSC, and SECAM. The components of the
AV-3000 series operate in a harmonized frequency range and can
thus be universally applied throughout Europe.
The wireless system of the AV-5800 system is especially designed for
the requirements of professional applications where a safe transmission
without interference must be ensured. This wireless system was deve-
loped due to the increasing assignment of the 2.4GHz frequency range
and the demand for additional transmission channels.
It operates in the frequency range of 5.725–5.875 GHz with a
transmitting power of 25 mW.
The frequency range is divided into 16 channels, where 6 channels
can be used for parallel operation (channels 1, 4, 7, 10, 13, and 16).
At a suitable antenna configuration, a parallel operation of up to 8
systems is possible.
The system is suitable for the transmission of standard video signals
of the formats: PAL, NTSC, and SECAM. The components of the
AV-5800 series operate in a harmonized frequency range and can
thus be universally applied throughout Europe.
Example of application:
One of the main applications is the transmission of video signals to
locations where it is impossible or only possible with great effort to lay
video cables.
For example, crossing streets, squares, and bodies of water. In these
cases, best results are achieved with transmitters and receivers for the
outer wall.
Frequency Transmitter Receiver
2.4 GHz AV-3030TX AV-3030R
5.8 GHz AV-5820TX AV-5810R
The AV-...RDX receivers are recommended to achieve larger transmis-
sion ranges. An external antenna can be connected to these receivers.
Please remember: antennas with a high gain only have very narrow
horizontal and vertical aperture angles. In order to fully utilize this ad-
vantage, pay attention to an exact alignment of the reception antenna
towards the receiver.

Simultaneously used channels:
In order to ensure an optimum reception, the following
free channel spaces should be kept:
2.4GHz range = 1 free channel space
5.8GHz range = 2 free channel spaces
With this configuration, it is possible to use up to
3 channels simultaneously in the 2.4Ghz range and up
to 6 channels simultaneously in the 5.8GHz range.
