2. Regarding the video transmitter, what are the frequencies available?

There are three frequencies to choose from 800Mhz, 1.2G, and 2.4G. But there is no 10W Power Amplifier for 150km at 2.4Ghz. So if the buyer wants to support a 150km transmission distance, only 800Mhz and 1.2G can be chosen.

3. Can you take a test video for me to see before shipping?

Of course, we also understand that wireless video transmission transmitters and receivers are very expensive. You are far away from the China factory. and hope that the goods you receive are fit for the best performance. If you pay special attention to a specific parameter or function, we can take some test videos based on the features you want to see, please feel free to contact us. It won't be shipped to you directly without your approval. Just like today, I tested and show the video to my client.

4. Can I use one 3-meter RF cable from the transmitter to the antenna?

Regarding the RF cable, our engineer doesn't recommend that you used so long. There will be a reduced 0.5dB for one meter RF cable. For 3 meter RF cable, the signal strength will be reduced by 1.5dB.

6. What types of video inputs port does your wireless video transmitter have?

Our wireless video transmitters have these types of video input interfaces: HDMI 1080P and 4K HDMI, CVBS composite, SDI, AHD, IP Ethernet, and BNC, or tell us what type you need, and our engineer will modify it to meet your demand.

7. What is the transmission distance supported by your wireless video transmitter?

Our transmission distance can be adjusted by adding power amplifiers. At present, the main ones are 15km, 30km, 50km, 80km, 100km, and 150km, which depend on the needs of customers. Of course, the transmission distances listed above are all within LOS the line-of-sight range. If there are obstacles between the transmitter and the receiver, NLOS (the non-line-of-sight), the transmission distance is greatly reduced, only 1km or 2km, depending on the number of intermediate obstacles and the local wireless environment.

8. What is one-way or two-way? Simples vs half-duplex, full-duplex

One-way means, We can only transmit and download video or data from the wireless video transmitter to the receiver in one direction, and we cannot upload video or data from the receiver to the transmitter. This type is also called simplex. Two-way means that, not only we can download video or data from our wireless transmitter to the receiver, but also we can upload the video or data from the receiver to the transmitter. This is very suitable for operating drones. You can not only see the real-time video transmitted from the drone but also upload the command to control the drone or the command to control the PTZ camera to adjust the angle to the transmitter. This can operate simultaneously. This type is also named half-duplex or full-duplex.

9. Does your HDMI video transmitter support encryption and receiver decryption?

Most Wireless video transmitters now support AES128 or AES256 bit encryption and decryption, depending on which model you choose. Please contact us to verify.

10. Can the frequency of the wireless video transmitter be modified after ordinary users receive the goods?

The frequencies of both the wireless video transmitter and the wireless video receiver can be modified. Users need to purchase additional parameter configuration boards. However, considering that the corresponding power amplifier and antenna are already fixed within a certain range when the goods are sent out. If the user adjusts the frequency of the transmitter, the corresponding power amplifier, transmitter antenna, and receiver antenna should also be modified to the same frequency, and these users need to be prepared. If not, it will cause the frequency of the wireless video transmitter to be different from the frequency of the antenna, making reception difficult. So please be sure to inform the correct frequency you need before placing an order. If it is for security or confidentiality, you can use the encryption and decryption functions of the transmitter and receiver, which can ensure that your video transmission is private.

11. I saw that your model is very similar to my needs, but I need to modify one of the parameters, is that possible?

Yes, all our product parameters can be customized according to customers' needs. If you have a special request, please let us know.

13. Can I buy modules of the transmitters and amplifiers only? I want to assemble them into my equipment.

We can, of course, supply wireless video transmitter modules and power amplifiers. For the first sample test, I recommend that you purchase the entire set of products because our engineers have optimized the parameters to achieve the best performance. After you have completed your test verification, you can remove the case or heat sink, install it on your device, and constantly adjust the parameters to achieve the best performance. In the future, you will be able to purchase only the modules or accessories that you require.

無線視頻數據音頻發射器和接收器, 雙向嘅, Download-Upload

A customer saw our real test video about the 2 瓦特功率放大器27公里遠程無線視頻發射器和接收器. He placed an order for this equipment. He hoped we would also bring the transmitter to the top of the mountain and the receiver to the seaside for testing before shipment. We have done our best to meet the needs of the customers. So we did it and created today’s video. If you want to learn about the actual transmission effect of long-range HD 1080P wireless video transmission, as well as how to operate it. Please keep watching.

Let’s begin by looking at the test location and distance on Google Earth. Search Meishajian, which is located on Shenzhen’s third highest peak, for no obstructions and simulate the situation of an aircraft with a transmitter in the air, ensuring that the test is within the line of sight. There are many high-rise buildings in a coastal city like Shenzhen. Finding a test environment with a line of sight and a distance of 30 kilometers is difficult. A T-shape is formed from here to the seaside of Nan’ao. Our receiving station is on the beach, and we can see the top of the transmitter from a distance of 27 公里.

We used the good distance tool to determine that the distance between the transmitter and the receiver is nearly 27km. In the following video, we can see from the receiver’s web UI page that the current transmitter to receiver distance is 27390 米.

Now let’s take a look at the situation of the transmitter on the mountain. The transmitter, IP network camera, and battery are placed on the rock. The trekking pole and red bubble belt make a red flag, which is fluttering in the wind so that the picture on the receiver screen is not static, it can be observed whether the wireless transmission video is smooth. The receiver is on the other side of the sea. The black transmitter is connected to two 30cm height transmitting antennas, the left part is the IP network camera, which is connected to the transmitter with a network cable, and the right part is a 12V battery, which powers the transmitter and the IP network camera.

Please try to position the transmitter and receiver vertically while transmitting. The signal strength will then be strong. Allow me to turn the transmitter and receiver in my hand, and the receiver monitor video will begin to move. The receiver will determine whether or not the video is smooth.

Now let’s take a look at the picture of the receiver.

The receiver is connected to the computer through the network cable. We can use the RTSP player on the computer and see the smooth picture directly.

We can also enter 192.168.8.11 in the browser to open the setting page of the receiver. On this parameter setting page, we can see various parameters of the current transmitter and receiver. An important parameter in this table is the distance and the signal strength. Now we can see that from the current transmitter to the receiver distance is 27390 米.

In the computer’s RTSP player, we can see that the wireless video transmission picture from the mountain transmitter has been kept very smooth, and the little red flag and the grass are fluttering in the wind without any lag, frozen, 馬賽克.

We are using an IP network camera to test, if your camera has HDMI 1080P, 4K HD, Sdi。, 阿赫德, or CVBS output, we also can add an encoder to the transmitter, connect your video output, and send out the IP living streaming to the transmitter. 在接收器, output the video to a computer through a network cable, or to a network video recorder.

It can be seen that the picture is very smooth,

Here we continue to play the videos recorded by the transmitter and receiver on the computer, and we can also answer some questions that some clients care about and always asked.

Two-Way full duplex Wireless Video Data Audio Transmission

第一, this set of wireless video data transmission transmitters and receivers is a two-way full duplex transmission system, it is like setting up an invisible wireless network in the air, two computers can be connected, and ping can be used in the computer’s cmd command state. In addition to transmitting video, data and audio can also be transmitted.

Power Amplifier options 2W, 5W, and 10W to support longer distance

第二, if you want to support longer distances, we can achieve longer distances by changing different amplifiers. 例如, 300MW, 2 瓦, 5 瓦, 10 Watts power amplifier, the corresponding transmission distance is 7 公里, 15 公里, 30 公里, 80 公里, 100 公里, the farthest can be transmitted to 150 公里, we also have a 110 km The actual test video. If you are interested, I can also edit it and upload it for everyone to watch.

Up to 150Km, 4 times of English Channel Width

第三, what is the concept of supporting up to 150 公里? It is equivalent to 93 英里. The UK is separated from Europe by the English Channel, and its width is only 35 公里, 噉係, 150 kilometers is equivalent to the width of 4 times English Channels. It can also transmit high-definition videos with good signals.

常見問題

1. 我應該為這款10W功率放大器收發器準備乜嘢電池?

該發射器和電池嘅電源都係 3A@28V. 在正常時間, 我哋用于測試嘅電池係7AH, 它可以工作2〜4小时. 如果您購買15AH可充電電池, 可連續工作約4~8小時.

2. 關於視頻發射器, 可用嘅頻率係幾多? 我哋可以選擇嗎？ 2.4 GHz作為選項，還是必須是1.4GHz或800MHz?

有三種頻率可供選擇，從800Mhz, 1.4g, 同2.4G.

但係冇10W功率放大器喺2.4Ghz下行駛150km. 所以如果買家想支持150km嘅傳輸距離, 只能選擇800Mhz和1.2G.

不僅可以輕鬆切換Web UI參數嘅頻率, 更改頻率後, 它還需要更換內部嘅功率放大器同同頻發射器和接收器天線. 因此，買方應在交貨前確認您需要的頻率. 天線根據此頻率定製.

3. 我可以使用一根3米長嘅RF電纜由發射器到天線呀？?

關於射頻電纜, our engineer doesn't recommend that you used it so long. 一米射頻電纜將減少0.5dB. 對於 3 儀表射頻電纜, 信號強度將降低1.5dB.
為咗支持長途, 最好少使用射頻電纜 1 米?
講真, 發射器非常細, 最好由發射器到發射器天線保持較短嘅距離. 發射器嘅電源電纜同由攝錄機到發射器嘅以太網電纜可以更長，因為冇好似RF電纜噉嘅損耗.

4. 它似乎支持IP攝錄機, 但我嘅視頻源或攝錄機係HDMI或SDI視頻輸出, 如何使用此發射器和接收器？

系嘅, 默認視頻輸入為IP RJ45以太網端口, 如果您的 相機係HDMI或SDI或AHD, 只需加上一個小編碼器盒即可解決此問題. 請檢查以下型號.

HDMI SDI AV input encoder IP RJ45 Ethernet output — HDMI SDI AV輸入編碼器IP RJ45以太網輸出

5. 我應該選擇嗎 800 Mhz或1.4G以獲得更好嘅接收效果? 有1.4G干擾GPS天線?

如果您所在嘅地區有DVB-T或DVB-T2數字電視信號, 這 電視頻率範圍為170-860Mhz, 它包括800Mhz, 所以選擇1.4G更好嘅.
因為GPS天線接收到GPS信號，冇人機上嘅GPS方向係向上嘅, 我哋嘅發射器天線指向下方，把信號發送到地面. 結果, 1.4G頻率對GPS嘅影響可以忽略不計.

6. 一套嘅包裝點? 毛重和尺寸?

包裝尺寸為 125 X 23 x 11厘米. 毛重：3.72公斤，體積重量：7.5公斤

7. 我是否應該喺參數設置中將跳頻設置為係?

關於跳頻, 工程師畀你一些建議.

由於系統頻率範圍為20Mb, 如果您的帶寬選擇為20Mb, 咁佢就唔可以跳咗 (只有一分). 如果選擇帶寬10Mb, 咁你有兩點可以跳, 如果選擇帶寬5Mb, 咁你就有了 4 要跳嘅啲.
如果1410Mhz卡住了, 然後1420Mhz都卡住埋, 由於頻率太近.
跳頻時, 數據或視頻傳輸將斷開, 您的視頻將被凍結.
在正常時間, 最好選擇跳躍唔係.
如果您的傳輸距離小於15~22km, 咁我哋仲有另一個選擇可供選擇, 頻率有110Mb, 即使你揀20Mb帶寬, 它有 5 跳頻可供選擇嘅啲.

8. 此型號是否支持將多發射器攝錄機連接到單個接收器? 例如, 使用 3 IP攝錄機 1 視頻發射機.

系嘅, 它支持.

對於發射機攝錄機多到一個信號接收器，有兩種解決方案.

9. 您的雙向無線視頻數據音頻鏈路糢塊是否撐inav嘅sbus?

如果您需要支持S.bus, 咁請喺發貨前話畀我哋, 我哋將將我哋嘅RS232修改為TTL.

我哋嘅TX900有三個RS232端口. 如果你需要它嚟撐S.bus, 只需要加上一個由S.BUS到RS232嘅小型轉換器就得了. ( Mini SBUS轉換糢塊Uart轉Sbus, Sbus到Unt ).

10. 我哋點樣先可以獲得RSSI, 快速信噪比, 轉到調試會話, 無需登錄網絡; 你是否有AT命令嚟獲取此信息?

RSSI無線鏈路狀態數據需要客戶 (如飛行控制器) 手動發送AT命令以獲取它. 它可以透過兩種方式獲得:

配置UST3 (數據端口3rd) 作為AT命令串口, 然後透過UNT3發送AT命令 (第3天) 以獲得. https://ivcan.com/change-d3-from-transparent-serial-port-to-at-command/
更新固件版本 1.5.1 以上, 這樣裡面就會多一個TCP服務器，供客戶透過TCP訪問，發送AT命令獲取無線狀態.
LED燈用于指示無線連接狀態 (例如, 如果無線鏈路已斷開, 燈會熄滅), 並且冇專用嘅外部引腳嚟通知客戶飛行控制.

抑或查看 UART AT命令列表喺呢度.

11. 呢啲空中糢塊是否向飛行控制器發出故障安全命令空中和地面糢塊之間嘅連接何時賴?

我哋無線視頻傳輸嘅串口係透明嘅, 並且冇主動向飛控發送任何數據. 係由地面站控制嘅.
It won't send the failsafe command, 但係你可以由信號指示燈中看到鏈路狀態指示燈.
係鏈路狀態信號強度指示器嘅手段
1. 㜴: 表示糢塊嘅無線鏈路未連接
2. 紅: 表示糢塊嘅無線鏈路已連接, 但係無線信號強度好弱
3. 橙: 表示糢塊嘅無線鏈路已連接, 無線信號強度中等
4. 綠: 表示糢塊嘅無線鏈路已連接, 並且無線信號強度非常強
我哋理解你希望擁有此功能, 如果飛機在飛行過程中失去信號，它將不會返回家園，因為飛行控制器唔會理解rc鏈路賴.
你需要看到鏈路狀態LED燈, 如果係橙色或紅色, 你應該提前控制飛機.

12. 如何升級無線視頻發射器和接收器嘅最新固件

請檢查升級固件設置, 透過以下連結下載最新嘅升級固件.

13. 您的系統是否能夠使用 3 節點? 由於我哋必須使用第3個節點作為發射器和接收器之間中心嘅中繼器.

在正常使用時, 一個節點作為發送器, 另一個節點作為接收器. 如果您需要支持遠距離或翻越山頂, 如下圖所示, 係, 請購買3rd Nord作為收割者.
你只需要將第三个節點放喺中間，將第三个節點設置為2D3U就可以了.

14. 如何透過軟件和外觀區分糢塊15km同30km?

在“Web UI參數打理”頁同“調試”部分,

AT命令

輸入 AT^DGMR?

如果你得到嘅結果係 6602, 然後是 15公里版本.

如果你得到嘅結果係 6603, 然後是 30公里版本.

15. 您的無線視頻發射器是否支持4K視頻?

4撐K視頻.
4K視頻流通常具有8Mbps以上, 而1080P視頻一般有2M以上, 所以我哋喺傳輸4K視頻時無線視頻傳輸嘅距離會比1080P短.

一言以蔽之, 視頻嘅清晰度越高, 傳輸距離越短.
視頻壓縮更細, 並且傳輸距離支持得更遠.

16. 發送視頻信號時, 如果數據包喺傳輸過程中賴, 接收方是否注意到並要求發送方再次發送賴嘅數據包?

在視頻傳輸過程中, 如果數據賴, 圖片會出現馬賽克或停滯, 凍結等現象.

在無線鏈路級別，將有有限數量嘅重傳 (答案係肯定嘅, 如果情況不好，都會發生數據錯誤). 端嘅上層應用程序唔會意識到它, 它都唔會要求發件人重新傳輸.

如果拉遠距離後某啲無線鏈路信號不好, 並且總是有位錯誤, 不可能將其設計為一直被重新傳輸, 這樣最終用戶體驗就會好差.

無線鏈路層嘅重傳機制有限. 我哋有測試tcp協議喺視頻傳輸層嘅傳輸 (嘗試透過TCP協議喺上層重新傳輸), 但測試發現冇明顯改善, 都將導致無法控制嘅延誤.

17. 變送器好熱點算?

飛機側產生嘅熱量比地面側大得多. 如果風扇正在運行, 檢查下風機嘅入風口同出風口是否 (散熱器兩端嘅位置) 被阻止
嘗試把空氣單元發射器嘅電源由24V更改為12~18V (發射功率將降低到35~36DB咁上下)
透過以下AT命令略微降低飛行器嘅發射功率: AT^DSSMTP="23" 設置後重新啟動

问题。: 呢啲設置係糢塊嘅最大功率啊? (24 Dbm)

答: 24dBm係鏈路糢塊嘅最大輸出功率, 以及PA嘅增益 (約14dBm) 需要添加. 24V電源PA輸出後的實際發射功率約為38dBm.

18. 你能否填寫以下表格以向我哋展示更多信息?

19. 是否可以把地面單位用于空中單位，反之亦然，只需更改設置即可?

空氣單元嘅區別 (器) 同地面單位 (接收機) 係兩點:

係設備類型: 空氣單元 (器) 係接入節點同地下單位 (接收機) 係中心節點.

二係下行鏈路同上行鏈路嘅速率比. 超過30公里, 最優惠嘅費率比率係 4:1 或者 3:2.

20. 插入接收器時會發生乜嘢 192.168.1.12 到現有路由器嘅LAN端口 10.220.20.1?

If you don't want to connect the receiver ethernet cable directly to the computer. 咁喺本地網絡上訪問接收器就唔易咗.

呢度有兩個解決方案畀你.

1. 在PC端添加192.168.1.x網段的IP地址 (PC可配置多個網段IP地址)

2. 修改無線視頻數據接收器嘅IP 192.168.1.12 到10.220.20.x網段嘅地址，以滿足您的本地網絡.

有關更多問題和解決方案, 請與您的局域網同事或工程師交談, 我哋嘅接收器就好似部有IP地址嘅電腦, 它應該令網段IP地址保持相同, 例如, 192.168.1.xxx.

21. 接收天線嘅底座係一個大型磁吸盤底座. 你可唔可以用U形夾具支架代替它啊?

系嘅, 我們可以用U形夾具支架更換接收器天線，以取代磁吸盤底座.

它好易固定喺桿子上. 磁性物品喺運輸過程中需要額外收費.

22. 如果我使用兩架冇人機, 一個係發射器, 另一個係中繼器, 它們由一個接收器控制. TX900是否支持控制任務飛機和中繼冇人機?

系嘅, 有三種解決方案可以做到這一點.
TX900有三個數據端口. 透過不同嘅透明串口進行區分, 如D2控制中繼飛機，D3控制任務飛機. 缺點是TX900接收器需要連接兩個串口，才能分別發送指令.
使用相同嘅透明串口批量發送數據, ，然後添加層協議 (如標頭信息) 對數據進行區分，以區分哪些飛機應該接收和處理數據. 缺點係發送同接收數據嘅處理複雜.
或者使用兩個接收器: 一個接收器用于任務飛機 (器), 另一個接收器用于中繼冇人機. 連接同操作更簡單.

還有問題?

可選TX900B 對於某些需要跳頻功能嘅客戶.

TX900B-2W支持頻率範圍為1420~1530MHz, 並且有110Mb帶寬可供使用. (800Mhz frequency range does not support this 110Mb bandwidth)
客戶可將工作帶寬設置為1.4M/3M/5M/10M/20MHz (但是，1.4M/3MHz可能唔適合視頻傳輸). 咁TX900B-2W就可以係 FHSS模式 (跳頻擴頻) 中心工作頻率將由系統自動選擇，並可進行跳頻 (1420~1530MHz之間) 在其工作期間.
客戶仲可以計劃使用成個1420~1530MHz嘅頻率信道，並將設備設置為喺固定頻率信道中工作.
TX900B-2W支持最遠距離22km.
除了支持嘅頻率範圍同最長距離, 外貌, 接口, 用戶界面, 操作。, 等陣, TX900B-2W與現有嘅TX900B-15km-2W相同.
TX900B-2W僅支持1420~1530MHz的頻率範圍, 它唔撐800MHz同2.4GHz頻率範圍.
有兩個版本, TX900B-2W-15公里, 同TX900B-2W-22km.
由於TX900B-2W頻率範圍為110Mb, 因此，如果您將工作帶寬配置為10Mb, 然後你會得到 11 指向跳躍.
TX900B撐110Mb跳頻帶寬，只有三個傳輸範圍可選, 22公里, 55公里, 同150公里.
