Question & Answer
The following are the most frequently asked
questions(Q-01); they are also
the most difficult to answer.
Q-01: As indicated in your brochure, the transmission
range is
specified in an empty space free of barriers. However,
with barriers,
what is the transmission range? How many floors or
how many walls can
be penetrated? What is the transmission range for a
2000mW transmitter
In a city? Why does it only transmit 200 meters while
the labeled
transmission range is 1000 meters?
A: Transmission range varies greatly with
environment. Barriers differ in
height, walls in thickness, woods in density, etc. If a
2000mW transmitter
can transmit 2-5 km, in places where there are many
buildings it is possible
to transmit a few tens to a few hundreds of meters; it
is also possible for
transmission to be completely blocked. In an
environment where barriers
are present, we can place outdoor antennas from two
ends of the
transmission as high as possible and in line-of-sight;
the maximum
transmission distance measured in this manner would
then be our specified
transmission range.
Q-02: How do I test a newly purchased wireless
audio-video transceiver
system?
A: STEPA: Connect the video camera to a power
source, connect it to the
TV monitor, and make sure that the camera and the
monitor are working
properly. STEP B: Make sure that the power sources
used in the transmitter
and the receiver can provide enough current; usually
an off-the-shelf
transformer will specify 1000mA when the output is
only 700mA.
Normally, the receiver requires 12V/600mA or more
while a 700mW or
lower transmitter will require 12V/800mA or more
(1W transmitter
12V/2A or more and 2W transmitter 12V/3A or more).
You can also use
rechargeable or storage batteries. STEP C: Connect
the camera, the
transmitter andthe power source properly; similarly
connect the monitor, the
receiver and the power source. Adjust the dials on the
receiver to
select the proper channel, making sure that it is the
same on the
transmitter. The system should then function
normally.
Q-03: During testing, how come I can only transmit
tens of meters
if you specify the transmission range to be several
thousand meters?
A: Due to the limitation of power sources, people
often place the
transmitter and receiver in different rooms where
transformers are
used to supply power. This inadvertently creates the
largest barrier
between the transmitter and the receiver, as steel-
reinforced
concrete is the strongest barrier for radio wave.
During testing,
please make sure that there are as little barrier as
possible between
the transmitter and the receiver; you can extend the
connection
wires so that there is light-of-sight between the
transmitter and
receiver antennas. This way, the true transmission
range of the
system can be determined.
Q-04: Why do I see rolling black lines on the monitor
while using
the wireless audio-video transceiver system?
A: This is usually caused by insufficient current from
the power
source of the transmitter or the receiver, or by a
low-quality
transformer. Switching to a proper transformer will
usually suffice.
Note that off-the-shelf transformers that are labeled
12V/800mA
usually output only around 300 400mA.
Q-05: What’s the resolution of your wireless audio-
video
transceiver system? Why are my transmitted images
blurry?
A: The system does not alter image resolution.
Resolution is
determined by the video camera. If your received
images are blurry,
please check your video camera.
Q-06: Can interference occur if another transceiver
system is being
used in the vicinity?
A: As far as we know, there are four channels
available in
transceivers manufactured by other companies while
there are
twelve channels available in our system. It is therefore
possible
forOur system to avoid using the same channel as
others. If you
select a channel other than the normal four, then
there will not be
any interference.
Q-07: When using your wireless audio-video
transceiver system,
can other people receive my transmission? Can you
provide
encryption services?
A: If others are using our wireless audio-video
transceiver system
in your area, then it is possible for them to receive
your signals. If
you have special requirements, we can provide
encrypted audiovideo
transceiver service.
Q-08: Your receiver has twelve channels, but your
transmitter has
only either seven or four channels. Can you provide
twelvechannel
transmitters?
A: Due to size limitation, our transmitters come with
only four or
seven channels. If you require the use of all twelve
channels in the
same location, we can provide transmitters with three
different
frequency ranges: 0.9GHz (four-channel), 1.2GHz
(four-channel),
1.3GHz (four-channel), with a total of twelve
channels. Our
receiver can receive all the above frequencies.
Q-09: Using your system, how many units can be
used in the same
area? In other words, how many transceiver points are
allowed?
A: Our civilian-class wireless audio-video transceiver
system can
provide twelve channels, thus twelve units can be
used. Our
military-class system can provide thirty channels, in
other words,
in the same area 30 points are allowed. However,
these need to be
custom-ordered.
Q-10: How many types of antennas are there? What
are their
different uses?
A: There are generally two types of antennas in
wireless audiovideo
transceiver systems: directional and omni-directional.
As
the names suggest, directional antennas transmit
radio signals in
some specified direction, and omni-directional
antennas transmit
radio signals in all directions. Usually, directional
antennas are
used in point-to-point transmission while omni-
directional
antennas are used in point-to-many transmission.
Q-11: Are external antennas used on the transmitter
or the receiver?
A: Both, although usually it is used on the transmitter.
Of course,
the system functions even better if antennas are used
on both the
transmitter and the receiver.
Q-12: Which system models require an external
antenna? What is
the actual effect of using an external antenna? Why
do I get a
shorter transmission range after I connected an
external antenna
compared to using the small built-in antenna?
A: In normal situations, wireless audio-video
transceiver systems
with transmission power larger than 300mW can use
an external
antenna; this can increase transmission range by 30%
– 70% in an
open environment without barriers. When using the
external
antenna, if the system does not function as well as
using the small
built-in antenna, then the only possibility is that the
external
antenna has not been connected properly. This
includes the
connections among the connectors on the antenna,
as well as the
connection between the antenna and the transmitter.
Especially,
the center-pin of the external antenna connector
must be precisely
inserted into the small hole in the transmitter’s
connector,
otherwise the external antenna will not function at all.
Q-13: What is the function of the wireless camera
platform/lens
transceiver system? How many camera platform/lens
can it
control? What protocols does it support? Does it have
built-in
decoders? Can it control the on-off switch, the wiper,
or the heater
switch?
A: The wireless camera platform/lens transceiver
system is used
in areas where it may not be convenient to place
wires. It remotely
and wirelessly controls the up, down, left, right, left-
up, leftdown,
right-up, and right-down motion of the camera
platform, as
well as
the aperture, focal length, and focus of the electric
zoom lens. It
can control 100 units of platform/lens. It supports a
built-in
proprietary protocol and no other protocols. The
system’s receiver
itself is a decoder, with a built-in keyboard. It can
control the onoff
switch, the wiper, and the heater switch.
Q-14: What is the function of the hard-disk video
recorder/matrix
wireless transceiver system (Wireless 485/232
command
transceiver system)? How many camera platform/lens
can it
control? What protocols does it support? Does it have
built-in
decoders? What transmission speed does it support?
Can it control
the on-off switch, the wiper, or the heater switch?
A: Simply, the wireless hard-disk video recorder
transceiver
system removes the wire connection between the
hard-disk video
recorder and the video camera. Its function is
identical to the
wireless camera platform/lens transceiver system,
with the added
functionality of video recording. Other functions are
determined
and supported by the decoder. There is no limitation
to the number
of platform/lens units it can control. It supports
protocols from
major manufacturers such as PELCO, PHILIPS,
Panasonic,
VICON, etc. It does not have a built-in decoder.
Supported speeds
are 1200, 2400, 4800 and 9600 baud.

Q-15: What is the difference between the wireless
camera
platform/lens transceiver system and the hard-disk
video
recorder/matrix wireless transceiver system (Wireless
485/232
Command transceiver system)?
A: These two systems function nearly identically. The
differences
are that the wireless camera platform/lens transceiver
system
operates independently, and can not be connected to
a hard-disk
video recorder; it also has a built-in proprietary
protocol, a
decoder, and a keyboard. On the other hand, the
hard-disk video
recorder/matrix wireless transceiver system (Wireless
485/232
command transceiver system) operates in
combination with the
hard-disk video recorder, the matrix, and other
computer
equipment; it does not have a built-in keyboard or
decoder.
Q-16: Why does the hard-disk video recorder/matrix
wireless
transceiver system (Wireless 485/232 command
transceiver
system) is completely dysfunctional?
A: It is almost certain that the connections are not set
up properly.
When using the system, please first directly connect
the hard-disk
video recorder with the camera platform/lens. Once
you are sure
both are function normally, remove the direct
connection and
connect the wireless system. The system should then
function
normally
