Transmisor y receptor de vídeo inalámbrico de costa a barco

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 metros, 20.6 kilómetros, o 12.8 millas.
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.
Del transmisor al receptor, it is sea level with no obstacles.
sin embargo, 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, datos, and audio broadband transceiver, supporting up to 20mbps.
Two-way wireless video, datos, 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 metros, you can also use 1.8 metros, 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, y receptores.
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.
Ancho de banda, Distancia de transmisión, Intensidad de señal, transmitter output power, clave, etc..
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 kilómetros.
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.
En el siguiente vídeo, 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.

Transceiver Networking Modes of three units

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

Cliente: ¿Puede proporcionar una cotización para suministrar un sistema de transmisor de video inalámbrico?, Operamos una draga y queremos transmitir video desde la costa a la draga a una distancia máxima de 5 kilómetros. Está en un entorno marino, por lo que tendría que ser robusto y también funcionar con 12 voltios sin conexión a internet.

iVcan: Antes de introducir un modelo específico, our engineer has some questions below.

1. ¿Necesita un sistema de transmisión unidireccional o bidireccional??
   De una sola mano, significa simplemente transferir el video desde la orilla a la draga.
   Bidireccional, means sending and getting the video or data from one side to another side.
2. ¿Está la cámara en la orilla o en la draga?? y el receptor está en la orilla o en la draga.
   Necesitamos considerar el caso especial del transmisor o receptor..
3. A menudo hay olas onduladas en el océano.. ¿A qué altura se pueden instalar la antena transmisora ​​y la antena receptora??

Cliente:

1. Necesitaríamos un unidireccional con la cámara transfiriéndose desde la costa a la draga.
2. La cámara estaría en la orilla al final de la tubería de descarga y el receptor y el monitor estarían en la draga para poder ver lo que sucede en la costa..
3. Adjuntamos un pdf con algunas imágenes que muestran la "configuración". También hay un mástil ubicado en tierra..
4. Tenga en cuenta que no hay conexión a Internet disponible en la draga..

iVcan:

DE ACUERDO, de una sola mano, Cámara HDMI en la orilla, el receptor en la draga, La distancia de transmisión es de 5 km., transmisor, y el receptor se instalará en un caso especial, (impermeable, a prueba de choques, spray anti-sal), con 3 Uds. Antena de fibra de vidrio de 1,8 metros de longitud.. (uno para el transmisor, dos para los receptores)

Recomendamos el siguiente modelo., COFDM-908T-5W

Aquí está el vídeo de prueba de 10W a 20km.

Usamos el COFDM(DVB-T) tecnología, which is similar to digital TV technology, sin necesidad de usar internet. (The camera and transmitter are like a TV company transmitting tower, Y el receptor es como una caja de TV en casa.)
