1. Must your price be 2X for TX and RX, correct?

Yes, for the two-way bidirectional wireless video data RC link, the quotation is on the base of one unit. If you need one transmitter and one receiver, then the unit price should be 2X. There are also customers who buy three or more sets; the middle one is the relay to extend the distance further. There are also customers with multiple transmitters and a receiver or one transmitter and multiple receivers. The quantity is according to your needs, so the cost is unit price X quantity.

2. What is the altitude estimates to achieve 50 km and 80 km?

The flying altitude of this drone depends on its actual application. The transmission distance we mentioned here is based on the visible range. LOS (line-of-sight). We have some clients who use weather balloons in the atmosphere (24-37km ) to monitor the operation and performance of the device. There are also more customers who use UAVs, just keeping the UAV higher than the obstacle on the grounds. In our test video on the ground, in order to test the transmission distance from 30 to 150 kilometers, it is often necessary to climb a high mountain of about 1,000 meters, so that the field of vision is wide.

3. What power amplifier should I choose? 2 watts or 5 watts?

The power amplifier is a signal enlarger for longer transmission distances. We can offer you 0.3W, 1W, 2W, 5W and 10W. Considering the 30km-50km transmission distance, it is better to choose 2 watts for 30~40km and 5 watts for 50~80km. 10 watts PA support 100~150km.

4. So each unit has a two-way communication function, correct? That means each unit can function as a repeater or relay function, correct?

Yes, every unit of the two-way bidirectional model is a transceiver. You can put any unit to act as the relay or repeater between the transmitter and receiver.

5. Each unit can transmit both video and telemetry data, correct?

Yes, each unit of TX900 has two RJ45 Ethernet ports for the IP camera. (also support extending more cameras by net switch), three data ports, and one bidirectional audio input-output.

6. Why does a 5-watt unit have several distance ranges? I mean there are 5 watts with 30 km, 55 km, and 80 km. Is it because of the software settings or what?

TX900 and Vcan1681 have software authorization on the transmission distance. Vcan1818 does not have this setting; the transmission distance depends on the power amplifier.

7. What are the weights of 5 watts and 10 watts ?

TX900: 5 Watts: 142grams and 10 Watts 242 grams

8. What is the delay (latency) of 5 watts at 55 km and 80km?

200-300ms video (including a camera to monitor) 30-60ms data

10. How about video quality between using 800 MHz and 1.4 GHz? Which is better, 55 km or 80 km?

The video quality is the same at 55km and 80km. The working frequency should be chosen in accordance with your local frequency authorization policy. If your local has DVB-T / DVB-T2 digital tv, the frequency range is from 170~860MHz, then 1.4GHz is recommended. Try to avoid the frequencies already in use in the local area as much as possible to reduce interference and avoid image quality freeze or mosaic.

11. Can the frequency be set correctly by the software?

Yes, you can set the frequency at the software Web UI or via the parameter configuration board tool. The antenna and PA power amplifier are working in some frequency range. Their frequency range is fixed when customized. So you should also change the antenna and PA when you change the frequency is out of their frequency range. For example, when you tell us you agree the working frequency is 1.4G, then the antenna and PA will work well at the 1.4G, even if you can change the transmitter and receiver working frequency to 800Mhz, you also need to change 800Mhz antenna and PA.

12. Do you have 1.2 GHz? This is better considering GPS frequency.

TX900 has three frequency ranges that can be optional: 800MHz, 1.4GHz, and 2.4GHz. The Vcan1818 working frequency range can be preset according to your project needs.

13. If I buy the 5-watt 30km, can I upgrade in the future to a 55km or 80 km license?

When you buy it, the power amplifier and max transmission range are fixed, and can not be expanded by software upgrades, except that you change the hardware of the transceiver module and PA. The assembly is complex, so you'd better buy a totally new one.

14. It would be nice to double-check if we can change the following parameters without rebooting the UAV radio: frequency; Bandwidth, and power amplifier.

Please note that our wireless transmitter module supports a frequency band. Such as 1427.9~1447.9MHz (1.4G) or 806~826MHz (800MHz), or optional 2401.5~2481.5MHz (2.4G). You must choose 1.4G, 800MHz, or 2.4G when buying it. (the antenna and PA will be customized according to the frequency band). In the frequency band, there are many frequency points. For example, the 1.4G range is from 1427.90 to 1447.0MHz. Like Wi-Fi, the module will auto-select the frequency point with the best current signal as the transmission frequency point, so you don't need to manually modify the frequency point unless you want to change to a frequency point with the worse signal. So our engineer doesn't suggest that you change the frequency manually. If you still need to do it, it should change the transmitter frequency first, then change the receiver frequency to the same as the transmitter. It is better for you to reboot the transmitter and receiver. If you don't reboot, it also might be working.

15. Our engineers would like to understand how to control the settings of the modem. Do you have an API description? What they are trying to understand is how this data link can be integrated with our system so that the data link settings are controlled from our ground control station. Thank you.

Please check the PC AT commands at the link below . https://ivcan.com/uart-at-command-for-wireless-video-transmitter-and-receiver/

16. Does your transceiver data transmission rate depend on transmission frequency? If yes, then what is the data transmission rate at the lowest frequency? And what is the data transmission rate at the highest frequency?

1. In the same frequency band (such as 1.4G), the transmission rate we generally refer to (also called the air interface rate) mainly depends on the wireless bandwidth (such as 10MHz, 20MHz) and wireless modulation parameters (such as QPSK, QAM16, QAM64). 2. Among them, the wireless bandwidth is set by the user (such as the wireless page under the web page), but the wireless adjustment parameters are automatically and dynamically set by the system. For example, QAM64 is used for short distances, and QAM16/QPSK is used for long distances. This is different from one-way COFDM image transmission. 3. For example, with the same configuration of 20MHz bandwidth, the air interface rate is as high as 30Mbps at short distances, but only 3~4Mbps at extreme distances. As for what wireless adjustment parameters to use under what conditions, or the currently used wireless adjustment parameters, customers need to explore and operate by themselves. 4. What frequency band the customer chooses should not be based on the transmission rate of the high-frequency band, but also based on the legitimacy of the frequency band and whether the frequency band is "clean". Theoretically, the radio wave in the high-frequency band corresponds to a short cycle, so the transmission time is short and the transmission rate is fast, but the specific theoretical value, I can't answer you, the actual value, the customer can test it through the speed measurement software (the "measure" page of the TX900 webpage is integrated with IPERF speed measurement)

17. In the communication transmission kit, I need a joystick that works with your equipment.

Support. Our system is a transparent transmission system. That means that video or data you input, we will transfer. How to control the robot is up to you. We have clients who use a PTZ camera; the receiver also has a joystick to control the PTZ camera, zoom, move or rotate.

18. The maximum distances that can be achieved in LOS (line of sight) and NLOS (non-line of sight) transmission?

1. In the visible range, how far our wireless transmission system can support depends on the transmission distance we mentioned and the matching power amplifier you choose when purchasing. Can be selected from 7km, 15km, 30km, 50km, 80km, 100km, and 150km. 2. If the transmission module you choose can support up to 100 kilometers, but you do not choose our default 5-watt power amplifier, then this distance cannot be reached. 3. It is difficult to answer how many kilometers our transmission system can transmit with non-line-of-sight. Because non-line-of-sight transmission distance depends on what is the obstacle between the transmitter and receiver? If it is a metal-enclosed box indoors or on a mountain, the transmission distance cannot be determined. Wireless video transmission signals are just like radio or GPS signals; they must be able to obtain signals in the presence of diffraction. Preferably in an open area.

19. Can these transceivers be used for land-based applications such as remote surveillance of an area?

This is perfectly fine. We also have customers who use it for long-term video surveillance in harsh situations such as borders, grasslands, mines, and reservoirs.

20. How many cameras can be connected to a single transmitter for smooth transfer of video to the receiving station?

1. Connecting more cameras also ensures smooth video, depending on the pixels you choose for video and the transmission distance. 2. Our default transmission bandwidth is 20Mbps. If you connect four or five cameras, the pixels of each camera reach 1080p, and the transmission distance is more than 30 kilometers, the video will occasionally freeze. When this happens, you can adjust the video format to a lower video pixel, or reduce the number of cameras connected to the transmitter.

21. Maximum number of transmitters that can be connected to a single receiver?

1. The answer to this question is basically the same as the previous one because the bandwidth rate of our single set of links is 20Mbps. Connecting more transmitters, each transmitter will occupy the corresponding bandwidth. 2. The smoothness of the video depends on the pixel and transmission distance of each camera you choose. Below is a video of us testing three transmitters and one receiver in our office. The picture is quite smooth. https://youtu.be/XI0fdp_LctU

22. If multiple receivers are placed in a particular location (single site).Then how will the transmitter distinguish which received it needs to be connected to?

1. Every transmitter and every receiver has its unique IP address. Which transmitter and camera you access from the receiver depends on whether you know the IP address you set beforehand. This ensures that even if many sets of transmitters or receivers are in the same location, you can only access devices whose IP addresses you know. 2. At the same time our transmission and reception also support AES encryption and decryption. Even if other unauthorized users know your IP address, they cannot access or view the video of the transmitter and camera to ensure the privacy of wireless transmission.

23. NVR integration procedure if live transmission and video recording are done simultaneously.

1. Most of our customers use the RTS player on their computers to watch or record the video content of the IP camera. 2. If you need to set up an NVR, our engineers can provide setup help according to your NVR-specific equipment.

24. Provision of circuit diagram and the architectural details of the transceiver?

1. My engineers and I will provide detailed help and remote configuration according to your project needs. 2. For specific technical information, according to your needs, we will judge whether it can be opened for free. But we will definitely ensure that you can use the device normally.

25. Is it possible for 100 kms or more long distance above sea?

If used 10W power amplifier is used , it can reach 150~200km. (NLOS) Because of the curvature of the earth, which creates obstructions between the transmitter and receiver, and requires longer distances, it is necessary to ensure that the aircraft flies high enough or use an intermediate mission aircraft as a relay.

26. We are conducting a long-range automatic flight today. The drone lost connection with the first time at 11Km and it did not auto-reconnect for the whole flight. When the drone landed automatically, we restarted both modules manually then they connected again. Data port D1 is not used. D2 is SBUS, D3 is a TCP server.

According to our understanding, the hottest part should be the air unit(the access node), because the environment inside the aircraft is very narrow and closed. 1. The next time you find this kind of problem, you need to use the elimination method, because in general, the probability of unilateral problems is higher. For example, if we suspect that there is a problem with the access node at the aircraft unit. Then we only restart the access node at the aircraft unit. Do not restart the central node on the ground side to see if you can connect after restarting the access node on the aircraft side; there is a high probability that there is a problem with the access node on the aircraft side. 2. If there are conditions, for example, if the wired network port of the access node on the aircraft is exposed, then you can connect it to the computer, and log in to the wireless link web page (default 192.168. 1.12). On the debug page, send any AT command , and check whether the wireless transmission system can respond to AT commands normally. 3. There is a link core module in our transmitter and receiver. It has a log function. Before the flight, it will always record the operation status of the wireless link. When there is a problem, return to the ground, export the log information, and send the log file to MorningCore Help to analyze the reason there. How to get Log files to analyze and resolve TX900 link interruption faults.

27. If we use the transceivers, how about security? It is safe because we do not want to hack our data from hackers else

Our wireless video data transmission system supports AES 128 encryption. Banks also use this encryption algorithm. For more information, you can google search AES128.

28. Can you show me the pictures of the UAV radio link antenna, U-shaped mountain clamp and coaxial cables?

1. U-shaped mountain clamp for 120cm Receiver fiberglass FRP antenna 2. 150cm Coaxial cables for 29cm transmitter antenna 3. 150cm Coaxial cables for 120cm receiver antenna

29. Have you tested that your 5w OFDM VTX can reach about 55 km directly without a repeater? If yes, what is the altitude of the drone?? Is it really LOS without any obstacles?

It can go directly to 55km, and the height of the aircraft should be more than 300 meters. It is best to see through without occlusion, or there is basically no occlusion near the antenna.

30. What is the power consumption of the 5 W VTX in voltage and current?

The average power consumption of the video transmitter is less than 1.1A@24V, and the average power consumption of the video receiver is less than 0.8A@24V. Power supply range 24~28V.

31. Can it use lipo batteries? 6S battery?

Support lipo batteries. 6S battery: 3.76 x 6 = 22.2V , 4.26 x 6 = 25.2V, 22.2-25.2V, no problem.

32. Please tell us the HS code for your long-range two-way drone video transmitter and receiver system?

Some clients used the HS code 8517799000.

33. Does it support the MAVLink protocol? I can just attach the air unit to my flight controller, or do I need to set the Mavlink protocol communication in the transceiver? So it doesn't need any configuration for MAVLink?

Yes, our long-range drone wireless transmitter and receiver supports MAVLink protocol and flight control. Please check the operation at the link below . https://www.youtube.com/watch?v=KJ7JMZZNgcI https://www.youtube.com/watch?v=9uI_KZlKeOQ

34. When shipped, your TX900 sample is equipped with three data ports that are TTL.

We can customize them for you according to your demands.

35. Are they in pairs if I buy the device? I mean, for the receiver and transmitter. I'm planning to transmit a video stream wireless with an 18km .

Yes, for the transceiver, it is better to buy at least 2 pcs for one pair. You need to buy two, one for transmission and one for reception.

36. Hello, I am interested in a communication line for UAVs for video and telemetry transmission.

36.1. What was the maximum range you received with a transmitter power of 10 watts and at what altitude? ivcan: TX900-10W-150km, our clients can work well at 150~200km at the 1000-meter altitude. We tested the 110km from the mountaintop to the seaside. https://youtu.be/r1X4AU1togE 36.2. Communication via Ethernet supports all standard protocols, but are there any restrictions on UDP protocols? Or is the modem absolutely transparent from a network point of view? ivcan: Yes, our wireless link is like an invisible network cable; it supports almost all Ethernet protocols, TCP/ IP, etc. TX900 also supports absolutely transparent transmission. 36.3 Encryption is only possible with NPP 128, or is it possible with 256? ivcan: TX900 supports AES128 encryption. 36.4 Is the mesh function available for this modem? ivcan: TX900B has the IP mesh function. There are three versions of the transmission distance: 3km, 10km, and 50km. 36.5 Is it possible to quickly change the operating mode (during the flight) of the repeater between point to point? ivcan: Sorry, it can not change the operating model during the flight. You can change the role of the transceiver to the transmitter, receiver, or repeater on the ground.

37. How to add the IP camera video stream to my mission planner software?

I have an IP camera attached to the airborne transmitter . The video feed is being received on the receiver side. I can see the video feed in the IPCAM application. But now I want the video feed inside my mission planner software. Answer: Right-click on the HUD. There are several options to choose from. Please get help at the below link. https://ardupilot.org/planner/docs/mission-planner-flight-data.html

38. My requirement was only 1 km but with a high bandwidth (for data and video), at least 30Mbps - 50Mbps (24VDC power). also kindly send a datasheet of the unit.

Ok, one of our TX900 sub-models can support 30 to 50Mbps.

39. Is TX900 possible to connect a camera with RTSP protocol to the transmitter?

Yes, the TX900 supports a camera with the RTSP protocol. It also supports an IP Ethernet protocol camera, which you can use to submit camera PTZ (Pan/Tilt/Zoom).

40. What is included in the package of your TX900 whole set?

The TX900 default set includes one transmitter and one receiver, two 29cm transmitters, and two 120cm receiver antennae.

41. Why do you recommend using D2 / D3 as the data port?

D1 is the transparent serial port of the core wireless link modem. It is designed to ensure real-time performance but not the serial port data frame structure. Customers who use the SBus interface basically connect to drones; besides using the SBus interface, this type of demand also requires connecting to the flight control's telemetry interface TTL. At present, customers prefer to connect to the telemetry interface through a serial to network connection. D1 cannot be used for sbus or serial-to-network connections, so only the D3 serial port can be connected to the flight control's telemetry port. Therefore, for customers who need an Sbus interface, it is recommended that D2 be used for Sbus, D3 use TTL level, and D1 is up to the customer.

42. Why should I re-power the air unit when the air unit and ground reconnection?

We have a situation when the air and ground units are disconnected, they won't be connected automatically. If I power the air unit off and on, it reconnects. Please show us more details, and our engineer will offer you a specific solution.

43. Does your model TX900 support 4K 60fps?

Now it supports 4K 30fps, 3840*2160@30fps

45. Can you give me the answers to the question list below ?

1. Recovery after link loss in milliseconds 30ms 2. Receiver sensitivity 2.4G: 20MHz-99 10MHz-103 5MHz-104 3MHz -106 1.4G 10Mhz -103 5Mhz -104 3MHz -106 800M 10MHz-103 5MHz-104 3MHz-106 3. Operating current 2W: <1.1A@12V 5W: <1A@24V 4. Video channels 1-2 IP camera is better. Just like 2-5 computers share one net cable to transfer data, the more data the net speed will be slow. 5. Body type Heat dissipation aluminum 6. Compatible with Pixhawk? The serial port is in transparent transmission mode, so it can transparently transmit Pixhawk data. 7. TX ON-OFF capability? AT command mode, AT+CFUN=0 turns off Tx AT+CFUN=1 turns on Tx 8. Working temperature -40 degrees Celsius to 55 degrees Celsius

46. Can TX900 support one-way video, two-way audio, and dual-channel data?

I want to connect one DVR or NVR with 4 fixed HD cameras, one CVBS camera, and one PTZ camera, then send the video out signal from the DVR over the wireless signal and control the view layout and the PTZ camera using the serial signal sent over the wireless signal. Yes.

47. TTL port on the air and ground TX900 radios. The tracking antenna needs GPS telemetry to function. My questions are:

1) Does the TTL on the TX900 ground radio receive the telemetry from the air TTL connected to the autopilot? Answer: Yes 2) Does the Air TX900 support serial to Ethernet TCP/UDP functionality for direct connection by GCS software like Mission Planner? Answer: Yes Please check more settings at the video link below . https://youtu.be/_CNjksp7KaM https://youtu.be/9uI_KZlKeOQ https://youtu.be/KJ7JMZZNgcI

无人机远距离视频发射器终极常见问题解答指南

无人机远距离视频发射器

无人机远程视频发射器是指用于无人机和无人机的5-150公里远程无线视频发射器和接收器. 很难选择和购买合适的型号.

你也有很多选择, 而且买错的成本非常高. 或许你也有很多疑问和疑惑. 这里, 我列出了一些问题和答案供您参考. 请联系我们要么 WhatsApp我们如需任何进一步的帮助, 我会尽力尽快准确地答复您的问题.

1. TX 和 RX 的价格必须是 2X, 正确的?

是, 对于双向双向无线视频数据RC链接, 报价以一个单位为基础. 如果您需要一台发射器和一台接收器, 那么单价应该是2X.
也有顾客购买三套或三套以上; 中间的是中继，可以进一步延长距离.
也有客户拥有多个发射器和一个接收器或一个发射器和多个接收器. 数量根据您的需要, 所以成本就是单价X数量.

2. 预计要达到的海拔高度是多少 50 公里和 80 千米?

该无人机的飞行高度取决于其实际应用. 我们这里所说的传输距离是根据可见光范围来计算的. THE (视线).

我们有一些客户在气氛中使用气候气球 (24-37千米 ) 监视设备的操作和性能.
使用无人机的客户也越来越多, 只需保持无人机高于地面障碍物即可.

在我们的地面测试视频中, 为了测试传输距离 30 至 150 公里, 通常有必要攀登大约的高山 1,000 米, 使视野开阔.

3. 我该选择什么功放? 2 瓦特或 5 瓦?

功率放大器是一个信号扩展，用于更长的传输距离. 我们可以为您提供0.3W, 1W¯¯, 2W¯¯, 5瓦和10瓦.
考虑30km-50km传输距离, 最好选择 2 30~40公里瓦数 5 瓦数50~80公里. 10 瓦PA支持100~150km.

4. 所以每个单元都具有双向通讯功能, 正确的? 这意味着每个单元都可以充当中继器或中继功能, 正确的?

是, 双向双向模型的每个单元都是收发器. 您可以将任何单元充当发射机和接收器之间的继电器或中继器.
wireless relay transmitter receiver system
two-way link transmitter receive repeater

5. 每个单元都可以传输视频和遥测数据, 正确的?

是, 每台 TX900 都有两个用于 IP 摄像机的 RJ45 以太网端口. (还支持通过网络交换机扩展更多摄像头), 三个数据端口, 和 1 个双向音频输入输出.

6. 为什么 5 瓦装置有多个距离范围? 我的意思是有 5 瓦特与 30 千米, 55 千米, 和 80 千米. 是软件设置的原因还是什么?

TX900和Vcan1681对传输距离有软件授权. Vcan1818没有这个设置; 传输距离取决于功率放大器.

7. 的重量是多少 5 瓦特和 10 瓦 ?

TX900: 5 瓦特: 142克和 10 瓦特 242 克

8. 什么是延迟 (潜伏) 的 5 瓦特 55 公里和80公里?

200-300女士视频 (包括用于监控的摄像头)
30-60毫秒数据

9. 关于遥测数据, 是否兼容MavLink协议, 因为我将使用 Pixhawk Ardupilot?

是, 支持

10. 使用之间的视频质量怎么样 800 MHz和 1.4 千兆赫? 哪个更好, 55 公里或 80 千米?

55公里和80公里时视频质量相同.
工作频率应根据您当地的频率授权政策选择.
如果您当地有 DVB-T / DVB-T2数字电视, 频率范围170~860MHz, 那么推荐1.4GHz.
尽量避开本地已使用的频率，减少干扰，避免画质卡顿或马赛克.

11. 软件能否正确设置频率?

是, 您可以在软件Web UI或通过参数配置板工具设置频率.
天线和PA功放工作在一定频率范围. 定制时它们的频率范围是固定的.
因此，当您改变频率超出其频率范围时，您还应该更换天线和 PA.
例如, 当您告诉我们您同意工作频率为1.4G时, 那么天线和PA就可以在1.4G下正常工作, 即使您可以将发射器和接收器工作频率更改为800Mhz, 您还需要更换800Mhz天线和PA.

12. 你有 1.2 千兆赫? 最好考虑 GPS 频率.

TX900具有三个频率范围可供选择: 800兆赫, 1.4千兆赫, 和2.4GHz.
Vcan1818工作频率范围可根据您的项目需求预设.

13. 如果我买5瓦30公里, 我可以在未来升级到 55 公里或 80 公里执照?

当你买的时候, 功率放大器和最大传输范围是固定的, 且无法通过软件升级进行扩展, 除非你改变了收发模块和PA的硬件. 组装复杂, 所以你最好买一件全新的.

14. 如果我们可以在不重新启动无人机无线电的情况下更改以下参数，那就太好了: 频率; 带宽, 和功率放大器.

请注意我们的无线发射模块支持的频段. 如1427.9~1447.9MHz (1.4G) 或 806~826MHz (800兆赫), 或可选2401.5~2481.5MHz (2.4G).
必须选择1.4G, 800兆赫, 购买时还是2.4G. (天线和PA将根据频段定制).
在频段内, 有很多频点. 例如, 1.4G范围是从 1427.90 至 1447.0MHz. 就像无线网络一样, 该模块将以最佳电流信号作为传输频率自动选择频率点, 所以不需要手动修改频点，除非你想换到信号较差的频点.
所以我们工程师不建议您手动更改频率. 如果你还需要这样做, 它应该首先改变发射器频率, 然后将接收器频率更改为与发射器相同.
最好重新启动发射器和接收器. 如果不重新启动, 它也可能起作用.

15. 我们的工程师想了解如何控制调制解调器的设置. 有API说明吗? 他们试图理解的是如何与我们的系统集成此数据链接，以便从我们的地面控制站控制数据链接设置. 谢谢.

请在下面的链接上检查PC .
https://ivcan.com/uart-at-command-for-wireless-video-transmitter-and-receiver/

16. 您的收发器数据传输速率是否取决于传输频率? 如是, 那么最低频率的数据传输速率是多少? 最高频率的数据传输速率是多少?

1. 在同一频段 (比如1.4G), 我们一般所说的传输速率 (也称为空中接口速率) 主要取决于无线带宽 (比如10MHz, 20兆赫) 和无线调制参数 (例如QPSK, QAM16, QAM64).
2. 他们之中, 无线带宽由用户设置 (比如网页下的无线页面), 但无线调节参数由系统自动动态设置. 例如, QAM64 用于短距离, QAM16/QPSK 用于长距离. 这与单向COFDM图像传输不同.
3. 例如, 相同配置20MHz带宽, 短距离空口速率高达30Mbps, 但在极远距离只有3~4Mbps.
至于什么条件下使用什么无线调节参数, 或当前使用的无线调节参数, 需要客户自行探索和操作.
4. 客户选择什么频段不应该以高频段的传输速率为标准, 还要根据该频段的合法性以及该频段是否属于 “干净的”. 理论上, 高频段的无线电波对应短周期, 所以传输时间短，传输速率快, 但具体理论值, 我无法回答你, 实际值, 客户可以通过测速软件进行测试 (该 “措施” TX900网页页面集成了IPERF测速功能)

17. 通讯传输套件中, 我需要一个与您的设备一起使用的操纵杆.

支持.
我们的系统是透明传输系统. 这意味着您输入的视频或数据, 我们将转移. 如何控制机器人取决于您.
我们有使用 PTZ 摄像机的客户; 接收器还有一个操纵杆来控制 PTZ 摄像头, 飞涨, 移动或旋转.

18. LOS可以实现的最大距离 (视线) 和非视距 (的非视距) 传送?

1. 在可见光范围内, 我们的无线传输系统能支持多远取决于我们提到的传输距离以及您购买时选择的配套功率放大器. 可以从7km选择, 15千米, 30千米, 50千米, 80千米, 100千米, 和 150 公里.

2. 如果您选择的传输模块最多可以支持 100 公里, 但您没有选择我们默认的5瓦功放, 那么这个距离就无法到达.

3. 很难回答我们的传输系统可以通过非线视线传输多少公里.
因为非视距传输距离取决于发射器和接收器之间的障碍物是什么?
如果是室内或山上的金属封闭盒, 无法确定传输距离.
无线视频传输信号就像无线电或GPS信号一样; 他们必须能够在存在衍射的情况下获取信号. 最好是在空旷的地方.

19. 这些收发器可以用于陆基应用，例如对区域的远程监视?

这很好.
我们也有客户在边境等恶劣环境下使用它进行长期视频监控, 草原, 地雷, 和水库.

20. 单个发射器可以连接多少个摄像机，以便将视频顺利传输到接收站?

1. 连接更多摄像头也保证视频流畅, 取决于您选择的视频像素和传输距离.

2. 我们默认的传输带宽是20Mbps. 如果连接四个或五个摄像头, 每个摄像头像素达到1080p, 且传输距离大于 30 公里, 视频偶尔会冻结. 当这个情况发生时, 您可以将视频格式调整为较低的视频像素, 或减少连接到发射器的摄像机数量.

21. 单个接收器可连接的最大发射器数量?

1. 这个问题的答案和上一个基本一样，因为我们单组链路的带宽速率是20Mbps. 连接更多发射器, 每个发射机都会占用相应的带宽.

2. 视频的平滑度取决于您选择的每个相机的像素和传输距离. 以下是我们在办公室测试三个发射器和一个接收器的视频. 画面相当流畅.

22. 如果多个接收器放置在特定位置 (单一站点).那么，发射器将如何区分需要连接的收到的收到的?

1. 每个发射器和每个接收器都有其唯一的 IP 地址. 从接收器访问哪个发射器和摄像头取决于您是否知道事先设置的IP地址. 这样可以确保即使许多组合发射机或接收器都位于同一位置, 您只能访问您知道 IP 地址的设备.

2. 同时我们的发送和接收也支持AES加密和解密. 即使其他未经授权的用户知道您的 IP 地址, 他们无法访问或查看发射器和摄像头的视频，以确保无线传输的私密性.

23. 实时传输和录像同时进行的NVR集成流程.

1. 我们的大多数客户使用计算机上的RTS播放器来观看或录制网络摄像机的视频内容.

2. 如果您需要设置 NVR, 我们的工程师可以根据您的 NVR 特定设备提供设置帮助.

24. 电路图的提供和收发器的架构细节?

1. 我和我的工程师将根据您的项目需求提供详细的帮助和远程配置.

2. 如需具体技术信息, 根据您的需求, 我们会判断是否可以免费开通. 但我们一定会保证您可以正常使用设备.

25. 是否有可能 100 公里或更长远的海面?

如果使用10W功率放大器 , 可达150~200公里. (NLOS)

由于地球的曲率, 这会在发射器和接收器之间产生障碍, 并且需要更长的距离, 需要保证飞机飞得足够高或者使用中间任务飞机作为中继.

26. 我们今天正在进行远程自动飞行. 无人机在11公里处首次失去连接，并且没有自动连接整个飞行. 当无人机自动降落时, 我们手动重新启动两个模块然后它们再次连接. 数据端口D1不使用. D2 是 SBUS, D3是TCP服务器.

据我们了解, 最热的部分应该是空气单元(接入节点), 因为飞机内部的环境非常狭窄和封闭.

1. 下次再发现此类问题时, 你需要使用排除法, 因为一般来说, 单方面出现问题的概率较高. 例如, 如果我们怀疑飞机单元的接入节点有问题. 然后我们只重启飞行器单元的接入节点. 地面侧中心节点不要重启，飞机侧接入节点重启后看能否连接; 大概率是飞机侧接入节点有问题.

2. 如果有条件的话, 例如, 如果飞机上接入节点的有线网口暴露, 然后就可以连接到电脑了, 并登录无线链接网页 (默认 192.168. 1.12). 在调试页面, 发送任何指令, 检查无线传输系统是否能正常响应AT指令.

3. 我们的发射器和接收器中有一个链路核心模块. 它有日志功能. 航班起飞前, 会时刻记录无线链路的运行状态. 当出现问题时, 返回地面, 导出日志信息, 并将日志文件发送到MorningCore Help来分析原因. 如何获取Log文件来分析和解决TX900链路中断故障.

27. 如果我们使用收发器, 安全性如何? 这是安全的，因为我们不想从黑客攻击我们的数据

我们的无线视频数据传输系统支持AES 128 加密. 银行也使用这种加密算法. 欲了解更多信息, 你可以谷歌搜索 AES128.
