Precautions
Installation height and separation distance
1. This product has a transmission distance of 250 meters under the same viewing
distance, unobstructed, best installation method, and the same antenna polarity, and
different code streams correspond to different distances; In the case of different
polarities, the distance will be shortened
2. To avoid human obstruction, the transmitter is 1.5-2 meters above the
ground and the receiver is 2 meters above the ground
3. When multiple sets of products work at the same time, please ensure that the
distance between the transmitters is at least 1 meter, and the working frequency
points between the products are staggered
4. When the receiver and other wireless products are placed and working, please
separate the receiver from other wireless products by more than 2 meters.
Frequency setting
1. When using a single set of products, it is recommended to set the frequency
point to CH5-CH9, because in many Wi-Fi coverage scenarios, the signal is
concentrated at low and high frequencies, and the spectrum occupancy rate
of the intermediate frequency is low
2. When two sets of the same product are used at the same time, the interval
between each set of products is more than 1 meter, and the frequency point is
set at more than 2 frequency points. For example, the first set of products is set
at CH5, and the other set of products is set at CH7 or CH8 or CH9. , Which is set
more than 2 frequency points apart
3. When multiple sets of the same product are used at the same time, each set of
products is separated by more than 1 meter, and the frequency point is set at 2
frequency points, that is, the first set of products is set at CH5, the second set is set
at CH7, and the third set is set On CH9, set up more than 2 frequency points
Environmental factors affecting wireless transmission
The following environment will affect the quality of wireless transmission, resulting in
confusing image sound
(Picture pause, noise, noise, etc.)：
a) Walls, large metal plates, and appliances will affect the wireless transmission, try
to avoid use in these environments；
b) When used under crowded conditions, the transmitter can be raised
as high as possible to more than 1.5--2 meters; the receiver should
be raised as high as possible to more than 2-3 meters
c) If there is a wireless product using 5GHZ nearby, it may also cause
interference to wireless transmission, which can be solved by switching the
frequency point. It is recommended to switch the product frequency point to
CH5-CH9 in case of interference。
d) Do not install the transmitter and receiver in a metal shelf, which will affect the
wireless transmission. If it is unavoidable, you need to consider leading the
antenna out
Cable connection
a) Try to avoid plugging and unplugging the HDMI / SDI cable of the transmitter and
receiver during normal use
b) Please try to connect the transmitter and the video source through HDMI / SDI,
and connect the receiver and the monitor before starting the transmitter and
the receiver
Product and antenna installation
a) When installing with the double-head screw that comes with this product,
please use the tightening screw to lock the product, do not hold the
product to rotate and tighten, to prevent the screw from being removed
from the product
b) When installing the transmitter and receiver, be sure to install
the antenna first, and then turn on the power, otherwise it may
cause damage to the product
