VDS
– Video Modem System
Poster
In
the CCTV industry, almost all the
cameras used coaxial cable to transmit
the video and the other signals. Generally,
when transmitting the video and the
other signals over a long distance,
there will be some interference appeared
and the video quality will become
weak. These are the degradation for
the current coaxial cable application.
In
order to solve such problems, we provide
a most innovative product VDS to improve
the video quality. Not only with video
signals transmission, the VDS also
can send the audio, alarm signals
and RS485 data and camera DC power
(12V or 24V) simultaneously, those
are all through one single coaxial
cable.
The
application of VDS is used on the
exist coaxial cable for CCTV camera
system, the transmission distance
can be easily reached to 500 meters
~ 1,000 meters, transmitting the video,
audio, alarm signals, RS485 date and
camera DC Power(12V or 24V). All the
signal quality can be still remained
in the best condition over a long
distance transmission, which the method
we used is by Multi-Carrier.
Currently,
we have a wide range of VDS products

Wireless Transmission
Set for CCTV
The
“Wireless Transmission Set”,
a high-end wireless transmission enhanced
version for point to point used. Same as
the transmission effect of Video Modem System
by using single coaxial cable, the Wireless
Transmission Set is able to transmit one-way
video, two-way audio signals and duplex
digital RS485 data in best quality.
When facing with the following situations,
the Wireless Transmission Set can completely
work out for you.
a)
Long distance transmission to 1 KM or 5
KM, even for 10 KM above.
b) Due to the environmental circumstance,
it’s difficult to install the cabling
or fiber optic transmission
link.
c) CCTV camera movable in the remote side
is required.
d) Due to the property reason, you can’t
install the cabling and the CCTV camera
in the indicated
place.
We
provide the Wireless Transmission Set with
low power and high power for short and long
distance transmission, the frequency we
used is 2.4GHz(ISM Band). Using low power(license
free) for short distance transmission, and
using high power(license required) for long
distance transmission. Would like to achieve
impossible mission? Just try the Wireless
Transmission Set.

FM
Adaptor – Cartone |
TM |
|
|
Overview the car radio sold in the
market, except the functions of car
radio currently has, any source outside
can’t be connected with the
car radio to play the sound. So far
as known in the market existed two
methods “Cassette Adaptor”
and “Phono Input” can
achieve this end.
However, in order to have better solution
to meet this requirement, we recently
develop a new product – FM Adaptor
called Cartone, which is just the
best method to bring all sources outside
into the car radio. As below are shown
the comparison of Cassette Adaptor,
Phono Input and FM Adaptor:
Cassette Adaptor:
Less and less car radio suppliers
provide the cassette in the car radio.
The cassette adaptor brings a cord
itself is inconvenient to use, the
audio quality not precise and the
audio volume difficulty to control
are insufficient to play the sound
through the car radio in the best
condition.
Phono
Input: Need to equip additional
high-power stereo equipment, generally,
the people who wish to equip it will
find the phono already be connected
with the car radio, only the professional
can handle it.
FM
Adaptor: The new product
FM Adaptor (Cartone) is designed to
use wireless solution. Can bring sources
outside to the car radio, playing
the sound in best quality at any time;
any stereo audio volume (100mV~5,000mV)
can be automatically controlled to
keep the level and video quality in
the best condition.
Reliability
and durability, small and compact
size, easy to carry anywhere. Simple
usage to connect the “Power
In” port of the Cartone to the
Cigarette-Lighter and connect the
“Audio In” port of the
Cartone to any of the sources outside,
such as Compact Disc (CD), Mini Disc(MD),
digital Compact Cassette(DCC), MP3
player and any audio source, even
it’s available with mobile phone,
if you have suitable connector to
connect with the FM Adaptor, your
voice can be also broadcast through
the car radio.
More than the use in car radio, the
Cartone also can be used in the desktop,
notebook, at home use or anywhere.
Only having a FM radio in you nearby,
connecting the Audio In of the desktop
or notebook ……etc to the
Carton, you can hear the sound from
the FM radio easily and conveniently.
Owning
the Cartone in hand, you don’t
need to care if the car radio has
been equipped the CD, DCC, MP3 or
any audio selection, you can enjoy
the great audio quality from any portable
device, playing the sound in the car
as like your car radio has been equipped
all of them, even for any of the future
products as related can be connected
perfectly as well. The unique product
brings convenience and quality life
to you, you mustn’t miss it.
