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 mita, 20.6 kiromita, ranei 12.8 maero.
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.
Mai i te kaituku ki te kaikawe, it is sea level with no obstacles.
Heoi, 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, raraunga, and audio broadband transceiver, supporting up to 20mbps.
Two-way wireless video, raraunga, 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 mita, you can also use 1.8 mita, 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, me nga kaiwhiwhi.
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.
Aratuku, tawhiti tuku, kaha tohu, transmitter output power, kupuhipa, 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 kiromita.
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.
I roto i te ataata e whai ake nei, 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.
Nga mihi mo to maataki, 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.

Kiritaki: Ka taea e koe te tuku korero ki te tuku i te punaha whakawhiti ataata ahokore, Ka whakahaerehia e matou he dredge me te hiahia ki te tuku ataata mai i uta ki te dredge mo te tawhiti rawa atu 5 kiromita. Kei roto i te taiao moana no reira me pakari me te rere tonu 12 volts me te kore hononga ipurangi.

iVcan: I mua i te whakauru i tetahi tauira motuhake, our engineer has some questions below.

1. Kei te hiahia koe ki te punaha whakawhiti kotahi-ara, rua-ara ranei?
   Kotahi-ara, Ko te tikanga ko te whakawhiti noa i te ataata mai i uta ki te dredge.
   Takirua-huarahi, means sending and getting the video or data from one side to another side.
2. Ko te kamera kei te takutai, kei te tarai ranei? ko te kaikawe kei te takutai, kei te dredge ranei.
   Me whai whakaaro tatou ki te keehi motuhake o te kaiwhakawhiti, kaikawe ranei.
3. I te nuinga o nga wa ka rere nga ngaru o te moana. Kia pehea te teitei o te antenna tuku me te antenna whiwhi ki te whakauru?

Kiritaki:

1. Ka hiahia matou ki tetahi huarahi me te kamera e whakawhiti ana mai i uta ki te dredge
2. Ka noho te kaamera ki uta i te mutunga o te putorino tuku, ko te kaikawe me te kaitutei kei runga i te dredge kia kite ai he aha kei te takutai.
3. Kua apitihia e matou he pdf me etahi pikitia e whakaatu ana i te 'whakaturia'. He rewa kei uta ano.
4. Kia mahara karekau he hononga ipurangi kei runga i te dredge.

iVcan:

OK, ara-tahi, He kamera HDMI kei uta, te kaiwhiwhi i runga i te dredge, Ko te tawhiti tuku he 5km, tuku, me te kaikawe ka whakauruhia he keehi motuhake, (parewai, whakaruruhau, rehu anti-tote), ki 3 pcs 1.8-mita te roa antenna muka karaihe. (kotahi mo te kaiwhakawhiti, e rua mo nga kaiwhiwhi)

I taunakihia e matou te tauira i raro nei, COFDM-908T-5W

Anei te ataata whakamatautau mo te 10W i te 20km.

I whakamahia e matou te COFDM(DVB-T) hangarau, which is similar to digital TV technology, me te kore hiahia ki te whakamahi i te ipurangi. (The camera and transmitter are like a TV company transmitting tower, a ko te kaiwhiwhi he rite ki te pouaka pouaka whakaata i te kainga)
