A customer saw our real test video about the 2 watt Kragversterker 27km langafstand draadlose videosender en ontvanger. 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 kilometer.

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 meter.

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 meter.

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, mosaic.

We are using an IP network camera to test, if your camera has HDMI 1080P, 4K HD, SDI, AHD, 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. By die ontvanger, 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

Eerstens, 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

Tweedens, if you want to support longer distances, we can achieve longer distances by changing different amplifiers. Byvoorbeeld, 300mW, 2 Watts, 5 Watts, 10 Watts power amplifier, the corresponding transmission distance is 7 km, 15 km, 30 km, 80 km, 100 km, the farthest can be transmitted to 150 km, 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

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

Fourth, if you need to control the PTZ camera, the receiver can also send control commands to adjust the direction and movement of the camera. This set of Wireless video data transmission transmitters and receivers also has three RS232 data interfaces, which can transmit various commands and data, and even connect with the drone’s flight control to remotely operate the drone.

AES 128 to protect video data safety

Fifth, this wireless video transmission device also supports aes128 for video encryption and decryption, so you don’t have to worry about your video, not safety, or being intercepted by others.

Two-Way Video Data Link Module + drywingsversterker

Sixth, Today we used 2 watt krag versterker. If your project demand, you can also purchase the two-way Wireless video data audio transmission transmitter and receiver module, and then configure your power amplifier.

1. What battery should I prepare for this 2 Watts, 5 Watts 10 Watts Power Amplifier transceiver?

2 Watts needs a 12V Power Supply, 5 Watts needs a 24V power supply, 10 Watts needs a 28V power supply

2. Met betrekking tot die video-sender, wat is die frekwensies beskikbaar?

There are three frequencies to choose from 800Mhz, 1.2G, en 2.4G.
Maar daar is geen 10W kragversterker vir 150 km teen 2.4Ghz nie. So if the buyer wants to support a 150km transmission distance, slegs 800Mhz en 1.2G kan gekies word.

3. Kan jy vir my 'n toetsvideo neem om te sien voor versending?

Natuurlik, ons verstaan ​​ook dat draadlose video-oordragsenders en -ontvangers baie duur is. Jy is ver weg van die China-fabriek. en hoop dat die goedere wat jy ontvang geskik is vir die beste prestasie.

As jy spesiale aandag gee aan 'n spesifieke parameter of funksie, ons kan 'n paar toetsvideo's neem op grond van die kenmerke wat u wil sien, voel asseblief vry om ons te kontak. It won’t be shipped to you directly without your approval. Just like today, I tested and show the video to my client.

4. Kan ek een 3-meter RF-kabel van die sender na die antenna gebruik?

Met betrekking tot die RF-kabel, our engineer doesn’t recommend that you used so long. Daar sal 'n verminderde 0.5dB vir een meter RF-kabel wees. Vir 3 meter RF kabel, die seinsterkte sal met 1.5dB verminder word.

5. It seems that your transmitter is supporting an IP camera, but my video source camera is HDMI or SDI video output, Hoe kan ek hierdie sender en ontvanger gebruik?

Ja, die verstek video-invoer is IP RJ45 ethernet pot, if your camera is HDMI or SDI or AHD, net plus een klein enkodeerderboks om hierdie probleem op te los, this encoder box will output IP living stream to the transmitter.

6. Watter tipe video-invoerpoort het jou draadlose videosender?

Ons draadlose video-senders het hierdie tipe video-invoerkoppelvlakke: HDMI 1080P en 4K HDMI, CVBS saamgestelde, SDI, AHD, IP Ethernet, and BNC, or tell us what type you need, and our engineer will modify it to meet your demand.

7. Wat is die transmissieafstand wat deur jou draadlose videosender ondersteun word?

Ons transmissieafstand kan aangepas word deur kragversterkers by te voeg. Huidiglik, the main ones are 15km, 30km, 50km, 80km, 100km, en 150 km, wat afhang van die behoeftes van kliënte.
Natuurlik, the transmission distances listed above are all within LOS the line-of-sight range. As daar hindernisse tussen die sender en die ontvanger is, NLOS (die nie-siglyn), die transmissieafstand word aansienlik verminder, slegs 1km of 2km, afhangende van die aantal intermediêre hindernisse en die plaaslike draadlose omgewing.

8. Wat is eenrigting of tweerigting? Eenvoudige vs half-dupleks, voldupleks

One-way means, Ons kan slegs video of data van die draadlose videosender na die ontvanger in een rigting stuur en aflaai, en ons kan nie video of data van die ontvanger na die sender oplaai nie. Hierdie tipe word ook simpleks genoem.
Two-way means that, nie net kan ons video of data van ons draadlose sender na die ontvanger aflaai nie, maar ons kan ook die video of data van die ontvanger na die sender oplaai. Dit is baie geskik vir die bedryf van hommeltuie. 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. Dit kan gelyktydig werk. This type is also named half-duplex or full-duplex.

9. Ondersteun jou HDMI-videosender enkripsie en ontvanger-dekripsie?

Most Wireless video transmitters now support AES128 or AES256 bit encryption and decryption, afhangende van watter model jy kies. Kontak ons ​​asseblief om te verifieer.

10. Kan die frekwensie van die draadlose video-sender gewysig word nadat gewone gebruikers die goedere ontvang het?

The frequencies of both the wireless video transmitter and the wireless video receiver can be modified. Gebruikers moet addisionele parameterkonfigurasieborde koop.
Maar, in ag genome dat die ooreenstemmende kragversterker en antenna reeds binne 'n sekere reeks vasgestel is wanneer die goedere uitgestuur word. As die gebruiker die frekwensie van die sender aanpas, the corresponding power amplifier, sender antenna, and receiver antenna should also be modified to the same frequency, en hierdie gebruikers moet voorbereid wees. Indien nie, dit sal veroorsaak dat die frekwensie van die draadlose videosender verskil van die frekwensie van die antenna, ontvangs moeilik maak. Maak dus seker dat u die korrekte frekwensie wat u benodig, inlig voordat u 'n bestelling plaas.
As dit vir sekuriteit of vertroulikheid is, you can use the encryption and decryption functions of the transmitter and receiver, wat kan verseker dat jou video-oordrag privaat is.

11. Ek het gesien dat jou model baie ooreenstem met my behoeftes, maar ek moet een van die parameters verander, is dit moontlik?

Ja, all our product parameters can be customized according to customersneeds. As jy 'n spesiale versoek het, laat ons asseblief weet.

12. Wat moet ek doen as my draadlose video-ontvanger 'n swak sein toon?

1. Change the place of the receiver to avoid potential local interference from magnetic solid environments.
2. Ensure that the antennas on both the transmitter and receiver are vertical.
3. Please raise the antennas of the transmitter and receiver to maintain a particular height difference.
4. Please look around to ensure that there are no obstacles between the transmitter and receiver.
5. Change the orientation of the receiver antenna.
6. If it doesn’t work, try moving the receiver to be near the transmitter’s position to see if it exceeds the effective wireless transmission distance.
7. Or consider adding a relay of the transmitting between the transmitter and receiver.

13. Kan ek slegs modules van die senders en versterkers koop? Ek wil hulle in my toerusting aanmekaarsit.

Ons kan, natuurlik, supply wireless video transmitter modules and power amplifiers.
Vir die eerste monstertoets, Ek beveel aan dat jy die hele stel produkte koop, want ons ingenieurs het die parameters geoptimaliseer om die beste prestasie te behaal.
Nadat jy jou toetsverifikasie voltooi het, jy kan die omhulsel of hitte-afvoer verwyder, install it on your device, en pas die parameters voortdurend aan om die beste prestasie te behaal. In die toekoms, jy sal slegs die modules of bykomstighede kan koop wat jy benodig.

14. To support longer distances, can I use a 10 Watt of 20 Watts PA (kragversterker)?

Ja, as jy nodig het, we can change 10 Watt of 20 Watts PA to support a more extended range.
