1500-MINI - 5.8GHz Wireless Audio-Video transmission system
AV-LiNK 1500-MINI series is set devices designed to Video and Audio transmission
in the 5.8GHz frequency. It’s used in CCTV systems to transmit Video from CCTV
cameras to DVR’s, matrix and monitors. Wireless devices facilitates expansion
of existing installations in places where technical conditions are difficult.
There also reduces installation costs. It has built-in directional antennas
with radio transmission distance up to 1500 m.
It’s used to mount inside or outside buildings walls. Small size and
convenient to regulation bracket provide unobtrusive and it doesn’t
require much space for installation. It’s perfect to transmit Audio-Video
signal between buildings situated near to each other and
inside sport or production halls.
It can be used to
transmit Video in industrial automation and control
systems, multimedia Audio-Video installations. Another implementation
are mobile video surveillance systems, used in construction of buildings
and duration of mass events, where it isn’t possible to use cables and
location is variable. AV-150-MINI is economical device, easy to install,
connect and
tuning. It doesn’t need specialized knowledge and
expensive measuring
devices.
Wireless transmission system has 7 independent
radio channels
designed to transmit Video from 7 independent sources. Due to digital
frequency supervision you can easily change radio
channels via Dip-switch.
Each set of MINI series transmits one Video
and Audio channels.
Video line in transmitter and receiver
have universal connector able
to connect coaxial or UTP cable which
facilitates installation. Input/output
for coaxial cable have special
clamps, you don’t need to use BNC connectors,
it’s protected from corrosion or mechanical damage. Input/output for UTP
twisted pair have
Video transformer with filter designed to get high
Video quality when
long cables are used.
Radio transmission systems are installed on outside of buildings very
often, as a result there are exposed to lightning and vandalism.
AV-150-MINI
has surge protection for Audio-Video line and power supply
designed to
protect from lightning, electrostatic overvoltage and
vandalism.
Set consist of transmitter, receiver, IP65 hermetic case, bracket, clamps to masts.
