This Manual details the product specifications, instructions for use,
precautions, and troubleshooting. Read the Manual carefully before using
the product. If you have any questions or difficulties in using this product,
contact the Company or the seller in time.
Product Features
Thunder is a wireless HD video transmission device with wall-mounted,
non-line-of-sight transmission features,supporting up to 1080P/60Hz video
resolution. This system is based on 1.4Ghz wireless network technology for
transmission. Image processing is performed using H.264 coding-decoding
technology, and thus the images are clearer and the latency is lower.
Brief Introduction
High-quality low-latency video footage
This product supports HD-SDI&3G-SDI input and output as well as HDMI full-HD
input and output, with the highest resolution of 1080P/60Hz. With the use of H.264
coding-decoding technology with high compression ratio and high definition, the
images have high definition, and the latency is as low as 70ms.
Wall-mounted and non-line-of-sight transmission features
This product is designed based on 1.4Ghz wireless network technology. The lower
frequency makes it have better penetrating characteristics and can be transmitted
under non-line-of-sight conditions, and this frequency is not easy to be interfered
by the external environment.
Point-to-point mode and streaming mode
This product supports switching between two operating modes, namely point-to-
point mode and RTSP streaming mode. In point-to-point mode, the video output
interface is HDMI or SDI. In RTSP streaming mode, the video streaming interface
is RJ45 network interface. There are more options for different applications.

Streaming Function
When using the functions in streaming mode, the transmitter needs to
switch to streaming mode. At this time, the word “RTSP” is displayed
on the transmitter’s OLED display, the SDI and HDMI at the receiver have
no video output, and the image is transmitted to the streaming media
software through the LAN port of the receiver for decoding display.
The streaming mode depends on software decoding. Comply with lots
of streaming media software. The following is an example of common VLC
streaming media software:After the transmitter and receiver establish a
network connection, the transmitter network indicator is always on,
the receiver network connection is normal; the transmitter is connected to
the HDMI or SDI video source, and the receiver’s network port is connected
to the streaming device.
Take the VLC of the PC as an example. After running VLC, select to turn on
the network stream.Fill in the address “rtsp://corresponding transmitter
encoding board IP address/media/live/0”. Click “Play” to start streaming.
Note that the transmitter must be connected to the video source, and the
IP address of the terminal streaming device (such as a computer) must be
the same network segment as the IP address of the encoding board.
Otherwise, the streaming will fail.

Each transmitter has one encoder, and its configuration and software
upgrading need to be implemented on its encoder . Since the receiver has
four decoders, the configuration and software upgrading need to be
implemented on its each decoder respectively.
Each transmitter has one wireless transmission module and one encoder.
Receiver has one wireless transmission module and four decoders.
All modules and each encoder/decoder have their respective IP address as
follows, and all configuration and upgrading operation must be
implemented under its own IP address.

Cautions
1. Environmental factors that affect wireless transmission
The following scenarios, which may result in pauses or noises,
can be problematic for the device.
a. Walls, large metal plates can pose a problem for the device. Avoid them if
possible or place the device in an optimal spot.
b. In crowded space, it is highly recommended to place the transmitter in a
higher position, approximately 1.5-2.5 meters and the receiver 2-3 meters
above the ground.
c. Do not place the transmitter or the receiver inside any metal enclosure,
which will severely affect transmission. If such case is inevitable, please
at least extend the antenna out of the enclosure.
2. Cabling
a. Please note that the HDMI ports are not hot pluggable.
b. Preferably, please first try connecting the receiver to the video source,
and receiver to monitor both via HDMI cable.
3. Device installation
a. Please make sure you install the antennas first before you set up the
device to avoid damage.
b. Fan the antennas out to achieve the best gain.
c. Please make sure antennas are properly installed before powering
on the device.

Troubleshooting
1. Mosaic or lagging on the screen
2. Black screen
a. Check to see if connecting to transmitter”or link connected
to transmitter, please check video source”appears on the screen.
If, instead, “link connected to transmitter, please check video source”
appears, please make sure the transmitter is properly connected to
the corresponding SDI/HDMI cable.
“ “
b. If blank or black screen appears after resolution switch, please
disconnect and reconnect the HDMI cable to the transmitter or
the receiver.
strength symbol does not appear. Check by following the instructions
in Section 16.1. If the signal strength symbol does appear but the VIDEO
symbol doesn’t, please check the video source and the corresponding
SDI/HDMI cables; If both symbols appear, but the switch goes black or
blank, please check the SDI/HDMI cable between the receiver and the
switch, change the resolution to 1080i 50 or 720p 50 to see if it is normal.
You can also check by connecting the SDI/HDMI cable to other monitor
to see if it is normal.
4. Green flicker in output
Make sure the HDMI ports of both the transmitter and receiver are
secured or tightly connected. Make sure the HDMI port of the camera
is also properly connected. If it is still not solved, please replace the
HDMI cables.
Please confirm if the following conditions have already occurred:
a. The transmitter is set up on a camera or handle, it should be 1.5-2m
above the ground, and the photographer’s body should not obstruct
the antenna’s cylinder. The receiver should be set up 2m or more
above the ground.
b. The antenna is tightened.
3. No output when the transmitter and the switch are connected
Check the signal strength and video symbol on the OLED screen of both
the transmitter and the receiver. They are not connected if the signal
