A customer saw our real test video about the 2 watt effektforstærker 27 km lang rækkevidde trådløs videosender og modtager. 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. Ved modtageren, 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

Først, 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

Anden, if you want to support longer distances, we can achieve longer distances by changing different amplifiers. For eksempel, 300mW, 2 Watt, 5 Watt, 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

Tredje, 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, det er, 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 + Power Forstærker

Sixth, Today we used 2 watts power amplifier. 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 Watt, 5 Watt 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. Med hensyn til videosenderen, hvad er de tilgængelige frekvenser?

There are three frequencies to choose from 800Mhz, 1.2G, og 2,4G.
Men der er ingen 10W Power Amplifier til 150 km ved 2,4Ghz. So if the buyer wants to support a 150km transmission distance, kun 800Mhz og 1,2G kan vælges.

3. Kan du tage en testvideo, som jeg kan se inden afsendelse?

Selvfølgelig, vi forstår også, at trådløse videotransmissionssendere og -modtagere er meget dyre. Du er langt væk fra Kina-fabrikken. og håber, at de varer, du modtager, passer til den bedste ydeevne.

Hvis du er særlig opmærksom på en bestemt parameter eller funktion, vi kan tage nogle testvideoer baseret på de funktioner, du ønsker at se, er du velkommen til at kontakte os. Det vil ikke blive sendt til dig direkte uden din godkendelse. Ligesom i dag, I tested and show the video to my client.

4. Kan jeg bruge ét 3 meter RF-kabel fra senderen til antennen?

Angående RF-kablet, our engineer doesn’t recommend that you used so long. Der vil være en reduceret 0,5dB for en meter RF-kabel. Til 3 meter RF kabel, signalstyrken vil blive reduceret med 1,5dB.

5. It seems that your transmitter is supporting an IP camera, but my video source camera is HDMI or SDI video output, Hvordan kan jeg bruge denne sender og modtager?

Ja, standard videoinput er IP RJ45 ethernet pot, if your camera is HDMI or SDI or AHD, blot plus en lille indkoderboks for at løse dette problem, this encoder box will output IP living stream to the transmitter.

6. Hvilke typer videoindgangsport har din trådløse videosender?

Vores trådløse videosendere har disse typer videoinput-interfaces: HDMI 1080P og 4K HDMI, CVBS komposit, SDI, AHD, IP Ethernet, and BNC, or tell us what type you need, and our engineer will modify it to meet your demand.

7. Hvad er transmissionsafstanden, der understøttes af din trådløse videosender?

Vores transmissionsafstand kan justeres ved at tilføje effektforstærkere. på nuværende, the main ones are 15km, 30km, 50km, 80km, 100km, og 150 km, som afhænger af kundernes behov.
Selvfølgelig, the transmission distances listed above are all within LOS the line-of-sight range. Hvis der er forhindringer mellem sender og modtager, nationale kontaktpersoner (den ikke-sigtelinje), transmissionsafstanden er stærkt reduceret, kun 1 km eller 2 km, afhængigt af antallet af mellemliggende forhindringer og det lokale trådløse miljø.

8. Hvad er envejs eller tovejs? Simple vs halv-duplex, Fuld duplex

One-way means, Vi kan kun overføre og downloade video eller data fra den trådløse videosender til modtageren i én retning, og vi kan ikke uploade video eller data fra modtageren til senderen. Denne type kaldes også simplex.
Two-way means that, ikke kun kan vi downloade video eller data fra vores trådløse sender til modtageren, men vi kan også uploade videoen eller dataene fra modtageren til senderen. Dette er meget velegnet til drift af droner. 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. Dette kan fungere samtidigt. This type is also named half-duplex or full-duplex.

9. Understøtter din HDMI-videosender kryptering og modtagerdekryptering?

Most Wireless video transmitters now support AES128 or AES256 bit encryption and decryption, alt efter hvilken model du vælger. Kontakt os venligst for at bekræfte.

10. Kan frekvensen af ​​den trådløse videosender ændres, efter at almindelige brugere har modtaget varerne?

The frequencies of both the wireless video transmitter and the wireless video receiver can be modified. Brugere skal købe yderligere parameterkonfigurationstavler.
Imidlertid, taget i betragtning, at den tilsvarende effektforstærker og antenne allerede ligger fast inden for et vist område, når varerne sendes ud. Hvis brugeren justerer frekvensen på senderen, the corresponding power amplifier, senderantennen, and receiver antenna should also be modified to the same frequency, og disse brugere skal være forberedte. Hvis ikke, det vil medføre, at frekvensen af ​​den trådløse videosender er forskellig fra frekvensen på antennen, gør modtagelsen vanskelig. Så sørg for at oplyse den korrekte frekvens, du har brug for, før du afgiver en ordre.
Hvis det er for sikkerhed eller fortrolighed, you can use the encryption and decryption functions of the transmitter and receiver, som kan sikre, at din videotransmission er privat.

11. Jeg så, at din model er meget lig mine behov, men jeg skal ændre en af ​​parametrene, er det muligt?

Ja, all our product parameters can be customized according to customersneeds. Hvis du har et særligt ønske, Vær venlig at informere os.

12. Hvad skal jeg gøre, hvis min trådløse videomodtager viser et svagt signal?

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 jeg kun købe moduler af sendere og forstærkere? Jeg vil samle dem i mit udstyr.

Vi kan, selvfølgelig, supply wireless video transmitter modules and power amplifiers.
Til den første prøveprøve, Jeg anbefaler, at du køber hele sættet af produkter, fordi vores ingeniører har optimeret parametrene for at opnå den bedste ydeevne.
