Two-way wireless video audio data transmitter-receiver used on the ground for 1-2 ڪلو ميٽر
Two-way wireless video audio data transmitter-receiver used on the ground for 1-2 km is more popular, and we get a new inquiry. Recently, a client wanted us to customize a two-way wireless video and audio data transmission system for him, which is used on the construction site. The typical ground usage scenario is that both the transmitter and the receiver are on the ground. The transmission range required by the customer is 1-2 ڪلوميٽر. If there are obstacles in the middle, a repeater can be added between the transmitter or receiver for video data and audio transfer. ساڳئي وقت ۾, in case of problems with wireless transmission, you can switch to wired transmission at any time. And there are 4-6 cameras at the transmitter position. So he chose the following one, Vcan1752, according to his requirement details, TX900-2W-15KM is recommended.
Two-way wireless video audio data transmitter-receiver used on the ground for 1-2 ڪلوميٽر.
The following are the specific requirements of the customer. I will answer and explain one by one according to his specific requirements, why another style is more suitable or recommended.

1. Here is my first requirement, is it bidirectional two-way on the audio and data, unidirectional one-way transmission is ok.
وڊيو: Vehicle -> ڪنٽرولر (unidirectional, هڪ رستو)
آڊيو: Vehicle -> ڪنٽرولر ; ڪنٽرولر -> Vehicle, (bidirectional, two-ways)
انگن اکرن: Vehicle -> ڪنٽرولر (UART interface needed); ڪنٽرولر -> گاڏي (UART interface needed)

2. Video Interfacing: 4 SDI video inputs at a vehicle. One HDMI output at the controller. With all 4 videos displayed on the screen from HDMI output. Please mention the video quality of each individual stream of the 4 videos.
The model Vcan1752: چار وڊيوز روٽ ويڊيوز ۾ ٺھيل آھن, ۽ مجموعي وڊيو معيار 1080P60 آهي. جيڪڏھن توھان کي ڏسڻ جي ضرورت آھي ھڪڙي ھڪڙي اعلي تعريف واري وڊيو, توھان مٽائي سگھوٿا سنگل وڊيو موڊ ۾.
تجويز ڪيل ماڊل TX900 پڻ سپورٽ ڪري ٿو 4-6 1080P تي وڊيو ان پٽز IP ethernet ڪئميرا ذريعي. چئن وڊيوز مان هر هڪ 1080P آهي.

4. Is this a card reader with an SD card in it? Or something else?
Is it for video storage purposes? I own a 1 Terabyte USB hard disk drive. Can I plug it in instead of the card reader with an SD card in it? (It is because I would prefer a 1TB storage for the incoming video)
The model Vcan1752 توهان ذڪر ڪيو آهي: USB انٽرفيس وڊيو محفوظ ڪري سگھي ٿو, ۽ توهان هڪ TF ڪارڊ يا يو ڊسڪ استعمال ڪري سگهو ٿا. I haven’t tried the 1TB one. It should not be a big problem. The commonly used one is 32GB.64GB.
تجويز ڪيل ماڊل TX900 does not support recording directly, but you need an extra NVR to record. We always use VLC or RTSP player as the monitor and recording in the computer.
5. Please show me the audio in/Out ports in both vehicle and controller module
The model Vcan1752: The audio is a separate pickup, which is input through the video port of the transmitter, and there is sound when the HDMI is decoded at the receiver, without a separate audio output port.
تجويز ڪيل ماڊل TX900 supports an ethernet camera with a mic and speaker, just plugin in the RJ45 on the transmitter and receiver is ok.
6. Does the recorded video contain audio? I would prefer incoming audio embedded in the recorded video.

8. The wireless video transmission range: NLOS minimum 1 ڪلوميٽر
Depending on your local using environment, you can refer to our test video. https://youtu.be/X-nu-QZYc5Y
10. Range extender:
I require a module to extend the range (Similar to a repeater station). It will increase the range by at least 500m and allow me to work in more complex NLOS situations. It takes the signal from the controller and relays it back to the vehicle and takes the signal from the vehicle and relays it back to the controller
The situation is a bit like this. It will help overcome extreme curvature. (Extender is not fixed to the ground! The image is symbolic)
If I place the repeater in between the controller and the vehicle, it will allow me to cross a more complex NLOS environment, and give me a greater range. (I am not looking for a very high powerful transmitter to eliminate the repeater station.)

The model Vcan1752: NOT support a range extender
تجويز ڪيل ماڊل TX900 supports a range extender. Customers need to purchase three sets of transceivers, one as a transmitter, the other as a receiver, and the third one can be placed as a relay in places with poor signal.
The relay is like the above picture. The drone in the sky is the extender. The transmitter and receiver are on either side of the mountain. UAVs in the sky can connect the transmitter and receiver.
سوال: The transceiver at the vehicle and controller are not identical. I assume You said buying 3 units meaning they are all identical.
جواب: The transceivers are actually the same as them. The transmitter, the receiver, and the extender are all the same product. They’re transceivers and can both receive and transmit data and audio.
11. Wired Transmission:
Let’s say the wireless transmission is not possible in a certain environment. And I have to go for wired transmission. مان ڪنٽرولر ۽ گاڏي جي وچ ۾ سڀني ڊيٽا کي وائرڊ ٽرانسميشن ذريعي منتقل ڪرڻ چاهيان ٿو (آپٽيڪل فائيبر). ڪنٽرولر تي هڪ سوئچ هجڻ گهرجي, جيڪو ڪندو سوئچ سسٽم جي وچ ۾ وائرليس COFDM ۽ وائرڊ آپٽيڪل فائبر مواصلات. (آپٽيڪل فائبر ڪميونيڪيشن ۾ ريپيٽر اسٽيشن جي ضرورت يا قابل اطلاق نه آهي, جيئن ڪنٽرولر ۽ گاڏي سڌو سنئون ڳنڍيل آهن).
- اچو ته چئون, سوئچ تي -> ڪنٽرولر ۽ گاڏي آپٽيڪل فائبر ڪيبل ذريعي ڳنڍيل آهن. (جيڪڏهن آپٽيڪل فائبر ڪيبل منقطع آهي, مواصلات واضح طور تي ناڪام ٿي)
- اچو ته چئون, سوئچ بند -> ڪنٽرولر ۽ گاڏي وائرليس COFDM سسٽم ذريعي ڳنڍيل آهن. (جيڪڏهن آپٽيڪل فائبر ڪيبل ڳنڍيل يا منقطع آهي, ڪو مسئلو ناهي, ڇاڪاڻ ته, اهو استعمال نه ڪيو وڃي, ۽ بنيادي طور تي هڪ مئل وزن آهي)

ماڊل Vcan1752 توهان جو ذڪر ڪيو آهي: سپورٽ نه
تجويز ڪيل ماڊل TX900 سپورٽ شامل ٿيل نيٽ ڪيبل لاءِ.
عام نيٽ ورڪ ڪيبل جي حمايت 100 ميٽر وڌ ۾ وڌ. جيڪڏهن توهان آپٽيڪل فائبر استعمال ڪندا آهيو, توهان کي هڪ آپٽيڪل ٽرانسيور ماڊل شامل ڪرڻ جي ضرورت آهي.
سوال: آڊيو ۽ ڪنٽرول ڪندو + موٽ ڊيٽا آپٽڪ فائبر جي ذريعي وڃو?
جواب: آپٽڪ فائبر هڪ نيٽ ڪيبل وانگر آهي, جيڪو ڪيبل ذريعي ٽرانسميٽر ۽ وصول ڪندڙ کي ڳنڍي سگھي ٿو. آڊيو ۽ وڊيو هڪ ئي وقت ۾ گڏ ٿين ٿيون.
سوال: جيڪڏهن ٻه ٽرانسورس ڪنٽرول منتقل ڪري سگھن ٿا + راءِ وائرليس, انهن کي ڪنٽرول منتقل ڪرڻ جي قابل هوندو + آپٽيڪل فائبر ذريعي موٽ. ڇو ته مون کي پنهنجي گاڏي جي حالت کي سنڀالڻ ۽ ڏسڻ جي ضرورت آهي جڏهن آپٽڪ فائبر استعمال ڪندي.
جواب: مهرباني ڪري RS232 RS485 ڊيٽا ٽرانسميشن سان فائبر آپٽڪ ٽرانسيور چونڊيو.
We are currently in the process of making a long-range Unmanned surface vehicle and we are searching for long-range antennas and transmitters for such a project. We need a range of at least 300km. Do You have something like that in your inventory?
زميني استعمال لاءِ, اهو 300 ڪلوميٽر منتقل ڪرڻ ڏکيو آهي, جيئن زمين گول آهي, ٽرانسميٽر کان وصول ڪندڙ تائين, ڪيتريون ئي رڪاوٽون آهن.
توهان کي غور ڪرڻ گهرجي 300 ڪلوميٽر هڪ ريپٽر ذريعي (ڊرون هوا ۾)
