最好 27 KM遠程無線圖傳接收器

為了更好的向客戶展示2W PA 30km遠距離圖傳發射器和接收器的實際支援距離和使用效果, 我們最近進行了實際測試，發現了一個梅沙峰, 從這裡到南澳海邊, 距離是 27 公里. This site passes through Dapeng Bay, the line of sight is visible, and there are no obstructions. It just simulates the use of the transmitter in the air and the receiver on the ground.

How to choose the best long-range video transmitter and receiver?

Please consider the below points before you buy. Here are some tips for you.
1. 傳輸距離 從發射器和接收器. The further the distance, the larger the power amplifier required; the larger the power amplifier, the higher the battery capacity requirement. 因此, you need to determine the wireless transmission distance according to your own project or drone.

2. LOS or NLOS, Is there any obstacle between the transmitter and receiver? All the transmission distances mentioned on this site are based on the LOS environment. If your use environment is NLOS, you need a larger power amplifier to have stronger diffraction and penetration capabilities. 也, consider placing a relay repeater module in the middle.

3. One-way or two-way transmission type? One-way is like TV or radio, you can get the video or data at the receiver only, and two-way like mobile phones and the internet, you can get living video and send data or joystick control commands to the transmitter’s camera from the receiver side remotely. Two-way has a downlink and an uplink both.

4. 公共廣播, 功率放大器, it is a signal enlarger, 例如, 1 瓦, 2 瓦, 5 瓦, 10 瓦, 20 瓦, big PA support longer range and strong signal to Anti-jamming. When choosing a power amplifier, you also need to consider power consumption, which will also increase the capacity of the battery.

5. 天線, A longer and bigger antenna will offer you better signal sensitivity. Omnidirectional FRP fiberglass antennas or automatic antenna tracking pan/tilts are recommended.

6. UART control, Do you need to send the AT command from the computer or portable tablet receiver via uart?

15. 27 KM long-range wireless video transmitter receiver Weight: 250 克

One of our clients bought our 2W PA (功率放大器) with 30km, up to 150km wireless video transmitter and receiver, but we can not find a 30km Line of sight place to test in our city, there are many high buildings. But luckily we found a place called Meishajian Peak, which is about 27 kilometers from the top of the mountain to the seaside.

Although the client chose a 2W-PA 30km transmission distance transceiver system, the test video is only 27km, So it is a 27 KM long-range wireless video transmitter-receiver.

Let us show you the transmitter and receiver first.

15-150km long-range wireless video transmitter and receiver for drone camera — 15-150km 遠距離無線視頻發射器和接收器，用於無人機相機

給你看清楚, we put the devices on one top and one bottom side for you.

送達前, we take it out for testing and a live demo. 在我們的超大城市很難找到一個測試的好地方, 需要30公里無障礙. 在這個測試中，我們有兩個團隊, 一個團隊將網絡攝像機和發射器帶到山頂 (Meishajian Peak), and another team takes the receiver and computer to the seaside (Nan’ao).

Where is the Air Unit Transmitter and Camera?

我們把發射器, 相機, 和岩石上的可充電電池.

How-to-connect-the-wireless-video-transmitter-ip-camera-battery-antenna

在地圖上, we can see the distance measurement is 27.85km.(17.30 英哩)

在山頂, 天氣不好，到處都是霧.

這裡我用我們上次的demo視頻給大家展示一下我們的位置和環境.

It was a sunny day, it was easy to watch the seaside.

希望你現在看到發射器和攝像頭在哪裡.

That time we were at the top of the mountain to test another composite CVBS video transmitter COFDM-912T.

它還測試並通過了距離發射器和接收器 26 公里.

Today The set we tested is a long-range video data link system on the base of OFDM, 這意味著發射器和接收器完全一樣，並且通過以太網連接器支持 RJ45 IP 網絡攝像頭視頻輸入.

If your camera has HDMI output, then it needs an extra HDMI encoder IP RJ45 output board, 它可以將 HDMI 視頻和音頻信號編碼為數字數據到此發射器.

在接收器, 它可以直接連接您的計算機或 NVR, We used a notebook computer monitor as the receiver screen, RTSP player, or VLC player to play the living video streaming from the transmitter and camera.

該機型組網方式支持點對點和點對多點星型網絡.
