20公里海上HDMI無線視頻發射器和接收器測試，用于船或由岸到船

20km over sea HDMI wireless video transmitter receiver test for boat or from shore to ship

首先, let’s take a look at the location of this test. We zoomed in on Google Earth, and we tested it in Shenzhen’s Dapeng Bay. It is used to simulate the long-range wireless video transmitter and receiver application at sea. Both the transmitter and receiver are at a very low altitude.

The location of our transmitter and camera is marked as the transmitter on Google Earth, which is located on a sea viewing platform in Dameisha Seaside Park, Yantian, 深圳. Please note that this is the beach, you can see it on the receiver’s monitor later.

Although we don’t have a ship to go 20 kilometers away from the shore for testing, we can find a place about 20 kilometers across the sea to receive the wireless video signal from the transmitter. Our receiver is located on the side of the coastal road.

We can see that the two locations’ distance is 20.57 kilometers through the measurement tool of Google Earth. I will also show the test environment of the transmitter and the receiver in the specific video later.

Now let’s go back to the transmitter and see how to assemble the antenna, 相機, and power.

We connect the transmitter antenna first, this is very important as there is a powerful amplifier built in. If the antenna is not connected and the power is turned on directly, the power amplifier is easy to be burned.

Then use the HDMI cable to connect the camera and the transmitter, This model support HDMI input only, we also customize it if you need SDI or IP camera input.

Then connect the transmitter to the power supply and turn it on.

The transmitter can be put on the floor, but try to place the transmitter antenna in the highest position possible, always keep the transmitter antenna in a vertical state to achieve the best transmission effect.

Now we show the video of the transmitter and receiver on the same screen, you can see that even if the distance is 20 公里, their positions are all near the sea, our HDMI wireless video transmitter system can transmit very well, and the video picture is clear and the signal is stable.

This device is HDMI one-way unidirectional wireless video and data transmission system, 我哋仲擁有用于IP攝錄機嘅雙向雙向無線視頻數據控制傳輸和無人駕駛船舶或冇人機嘅控制. 請喺衕一天觀看我哋嘅其他測試視頻.

在接收器上, 我們可以使用一根天線或兩根天線來增強接收效果.

讓我們仔細看看接收器的位置, 它位於發射機和攝錄機對面嘅沿海公路隔离.

如果你有任何需要使用無線視頻嘅項目, 數據和控制發射器和接收器, 叫 聯繫我們, 我哋會儘可能咁模擬您的使用場景，以測試我哋嘅設備是否能滿足您的要求. 感謝你抽出寶貴時間觀看我哋嘅測試視頻.
