Test Video for shore-to-boat wireless video transmitter and receiver

Do you know how far two-way wireless video and data transceivers transfer at sea level?
Let us take a look at the test location first, Shenzhen Dapeng Bay.
At Google Maps, we can measure the distance from the transmitter to the receiver.
It is 20650 मीटर की दूरी पर, 20.6 किलोमीटर की दूरी पर, या 12.8 मील.
The transmitter and camera are located on the Dameisha sea viewing platform
and the receiver and computer are next to the seaside road on Dapeng island.
From the transmitter to the receiver, it is sea level with no obstacles.
तथापि, both are close to sea level, and the ground will absorb signals
Our tests simulate transmission scenarios between ships at sea or to shore.
Let’s first see the transmitter and camera.
What you see currently is the IP ethernet camera and the battery that powers it.
We are located on a sea viewing platform.
Because it is a two-way transmission, there are two transmitting and receiving antennas, to ensure a good transmission signal.
Two antennas are connected to the transmitter
The blue one next to the transmitter is the battery, and a network cable connects the transmitter and the ethernet camera.
Two-way wireless video, डेटा, and audio broadband transceiver, supporting up to 20mbps.
Two-way wireless video, डेटा, and audio broadband transceiver, supporting up to 20mbps.
It can provide video surveillance, voice talking, or internet services from shore to ships on the ocean.
The weather is very good today and there are many tourists on the beach. If you have the opportunity to come to China, we can come here to test together.
The length of the antenna we use is 0.8 मीटर की दूरी पर, you can also use 1.8 मीटर की दूरी पर, and install the antenna as high as possible.
Through the feeder cable, we connect the antenna to the transceiver placed on the ground.
We used two batteries, one to power the transceiver and one to power the camera.
The transceiver has two networking modes: point-to-point one transmitter and one receiver, or IP mesh star networking for multi-transmitter and multi-receiver.
Now let’s look at the receiver and computer side.
Located on the Dapeng Peninsula, across the sea from the transmitter.
On the seaside road, you can see two receive antennas, computers, and receivers.
Next time we should bring a tripod to install the receiving antenna;
You also can use an auto-tracking antenna that supports directional antennas.
Let’s take a look at the computer monitor and see the video sent by the transmitter.
The computer is connected to the receiver via a network cable.
What we see now on video is a screen recording on a computer monitor connected to a receiver.
On the computer desktop, we have two windows, one is the real-time video screen, and the other is where various parameters can be adjusted.
बैंडविड्थ, संचरण दूरी, सिग्नल की शक्ति, transmitter output power, password, आदि.
This bidirectional video data transceiver can have two network ports, a data serial port and a control serial port.
It has two built-in 5-watt amplifiers, so it is 2X5W.
If it is from a drone in the air to a receiver on the ground, it can support 80-100 किलोमीटर की दूरी पर.
It includes real-time video downloading and is connected to the flight control, so you can control the drone and download real-time data of the drone.
We also have customers using this two-way video data transceiver for drones, ground mini robot vehicles, and ocean unmanned ships.
If you have special purposes, we can also customize functions according to your needs.
The test was a complete success.
In the following video, I will show the progress at 10x speed.
Let’s take a look at the test environment at the receiver side.
Let’s take a look at the test environment at the transmitter side.
Thanks for your watching, please contact us if you have any questions about the bidirectional video data transmitter and receiver for the camera.

Transceiver Networking Modes of three units

I want to have a wireless video transmitter and receiver from the shore to the boats.

ग्राहक: क्या आप वायरलेस वीडियो ट्रांसमीटर प्रणाली की आपूर्ति के लिए कोई उद्धरण प्रदान करने में सक्षम हैं?, हम एक ड्रेज संचालित करते हैं और किनारे से ड्रेज तक अधिकतम दूरी तक वीडियो प्रसारित करना चाहते हैं 5 किलोमीटर की दूरी पर. यह समुद्री वातावरण में है इसलिए इसे मजबूत बनाने और चलाने की भी आवश्यकता होगी 12 बिना इंटरनेट कनेक्शन के वोल्ट.

आईवीकैन: Before introducing a specific model, our engineer has some questions below.

1. Do you need a one-way or two-way transmission system?
   एक तरफ़ा रास्ता, means just transferring the video from the shore to the dredge.
   दो-तरफा, means sending and getting the video or data from one side to another side.
2. Is the camera on the shore or dredge? and the receiver is on the shore or the dredge.
   We need to consider the special case of the transmitter or receiver.
3. There are often undulating waves in the ocean. How high can the transmitting antenna and receiving antenna be installed?

ग्राहक:

1. We would need a one-way with the camera transferring from shore to the dredge
2. The camera would be on the shore at the end of the discharge pipe and the receiver and monitor would be on the dredge so can see what is happening on shore.
3. We have attached a pdf with some pictures which show the ‘set up’. There is a mast located onshore as well.
4. Please be aware that there is no internet connection available on the dredge.

आईवीकैन:

ठीक, एक तरफ़ा रास्ता, HDMI camera on the shore, the receiver on the dredge, transmission distance is 5km, ट्रांसमीटर, and receiver will be installed a special case, (जलरोधक, shockproof, anti-salt spray), साथ में 3 pcs 1.8-meter length fiberglass antenna. (one for the transmitter, two for the receivers)

We recommended the below model, COFDM-908T-5W

Here is the test video for 10W at 20km.

We used the COFDM(टी) प्रौद्योगिकी, which is similar to digital TV technology, with no need to use the internet. (The camera and transmitter are like a TV company transmitting tower, and the receiver is like a tv box at home)
