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 meters, 20.6 kîlometre, an 12.8 miles.
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.
Ji veguhêz ber bi wergirê, it is sea level with no obstacles.
Lebê, 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, jimare, and audio broadband transceiver, supporting up to 20mbps.
Two-way wireless video, jimare, 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 meters, you can also use 1.8 meters, 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.
Bandwidth, transmission distance, hêza sînyala, transmitter output power, şîfre, hwd..
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 kîlometre.
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.

Kirrîxwaz: Ma hûn dikarin ji bo peydakirina pergalek veguheztina vîdyoyê ya bêtêl bertekek peyda bikin, em xelekek dixebitînin û dixwazin vîdyoyê ji bejê berbi darê veguhezînin ser dûrahiya herî zêde 5 kîlometre. Ew di hawîrdorek deryayî de ye ji ber vê yekê pêdivî ye ku bi hêz be û her weha bi rê ve bibe 12 volt bêyî girêdana înternetê.

iVcan: Berî danasîna modelek taybetî, our engineer has some questions below.

1. Ma ji we re pergala veguheztina yek-alî an du-alî hewce ye?
   Birçî me, tê vê wateyê ku tenê vîdyoyê ji qeraxê berbi darê veguhezîne.
   Du-alî, means sending and getting the video or data from one side to another side.
2. Kamera li ser qeraxê ye an diavêje? û wergirê li qeraxê ye an jî li ser deryayê ye.
   Pêdivî ye ku em rewşa taybetî ya veguhezker an wergir bifikirin.
3. Di okyanûsê de gelek caran pêlên gemarî hene. Antenna ragihandinê û antenna wergirtinê çiqas bilind dikare were saz kirin?

Kirrîxwaz:

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. Ji kerema xwe hay ji xwe hebin ku pêwendiya înternetê li ser dredge tune ye.

iVcan:

OK, birçî me, HDMI camera on the shore, the receiver on the dredge, transmission distance is 5km, stefartî, and receiver will be installed a special case, (bêpergal, shockproof, spreya dijî xwê), bi 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(DVB-T) teknolocî, 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)
