A customer saw our real test video about the 2 Watt Amplifier Power 27km Veguhezkar û wergirê vîdyoya bêtêlê ya dûr-dirêj. 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 kîlometre.

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 meters.

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 meters.

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, mozaîk.

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. Li wergir, 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

Yekem, 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

Duyem, if you want to support longer distances, we can achieve longer distances by changing different amplifiers. Bo nimûne, 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

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

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. Di derbarê veguhestina vîdyoyê de, frekansên berdest çi ne?

There are three frequencies to choose from 800Mhz, 1.2G, û 2.4G.
Lê ji bo 150km li 2.4Ghz Amplifikatorê Hêza 10W tune. So if the buyer wants to support a 150km transmission distance, tenê 800Mhz û 1.2G dikare were hilbijartin.

3. Hûn dikarin ji min re vîdyoyek ceribandinê bavêjin ku ez berî şandinê bibînim?

Bê guman, em jî fam dikin ku veguhezter û wergirên veguheztina vîdyoya bêtêl pir biha ne. Hûn ji kargeha Çînê dûr in. û hêvî dikim ku tiştên ku hûn distînin ji bo performansa çêtirîn maqûl in.

Ger hûn bala xwe bidin pîvanek an fonksiyonek taybetî, em dikarin li ser bingeha taybetmendiyên ku hûn dixwazin bibînin, hin vîdyoyên ceribandinê bigirin, ji kerema xwe bi me re têkilî daynin. Ew ê bêyî pejirandina we rasterast ji we re neyê şandin. Mîna îro, I tested and show the video to my client.

4. Ma ez dikarim yek kabloya RF ya 3-metreyî ji veguhezderê berbi antenna bikar bînim?

Di derbarê kabloya RF de, our engineer doesn’t recommend that you used so long. Ji bo yek metre kabloya RF dê 0,5dB kêm bibe. Bo 3 metre kabloya RF, hêza sînyala wê bi 1,5dB kêm bibe.

5. It seems that your transmitter is supporting an IP camera, but my video source camera is HDMI or SDI video output, Ez çawa dikarim vê transmitter û wergir bikar bînim?

Erê, têketina vîdyoya xwerû IP RJ45 ethernet pot e, if your camera is HDMI or SDI or AHD, ji bo çareserkirina vê pirsgirêkê tenê yek qutiyek şîfreker a piçûk, this encoder box will output IP living stream to the transmitter.

6. Çi celeb porta têketina vîdyoyê ya weya vîdyoya weya bêtêl heye?

Veguhezînerên meyên vîdyoyê yên bêtêl van cûreyên têkelên têketina vîdyoyê hene: HDMI 1080P û 4K HDMI, CVBS pêkhatî, SDI, AHD, IP Ethernet, and BNC, or tell us what type you need, and our engineer will modify it to meet your demand.

7. Dûrahiya veguheztinê ya ku ji hêla veguhezera vîdyoya weya bêtêl ve hatî piştgirî kirin çi ye?

Dûrahiya veguhestina me dikare bi lêzêdekirina amplifikatorên hêzê ve were sererast kirin. Naha, the main ones are 15km, 30km, 50km, 80km, 100km, û 150 km, ku bi hewcedariyên xerîdaran ve girêdayî ye.
Bê guman, the transmission distances listed above are all within LOS the line-of-sight range. Ger di navbera veguhezkar û wergir de astengî hebin, NLOS (ne-xêz-dîrîn), dûrahiya veguhestinê pir kêm dibe, tenê 1km an 2km, li gorî hejmara astengên navîn û hawîrdora bêtêlê ya herêmî.

8. Çi yek alî yan du alî ye? Simples vs nîv-duplex, full-duplex

One-way means, Em tenê dikarin vîdyoyê an daneya ji veguhezkara vîdyoya bêtêl ji wergirê bi yek rê ve bişînin û dakêşin, û em nikarin vîdyoyê an daneyê ji wergir li ser veguhêz bar bikin. Ji vê cureyê re simplex jî tê gotin.
Two-way means that, ne tenê em dikarin vîdyoyê an daneyê ji veguhezera xweya bêtêlê berbi wergirê dakêşînin, lê di heman demê de em dikarin vîdyoyê an daneyê ji wergir li ser veguhêz bar bikin. Ev ji bo xebitandina dronên pir maqûl e. 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. Ev dikare bi hevdemî tevbigere. This type is also named half-duplex or full-duplex.

9. Ma veguheztina vîdyoya weya HDMI piştgirî dide şîfrekirin û şîfrekirina wergirê?

Most Wireless video transmitters now support AES128 or AES256 bit encryption and decryption, li gor kîjan modela ku hûn hilbijêrin. Ji kerema xwe ji bo verastkirinê bi me re têkilî daynin.

10. Ma piştî ku bikarhênerên asayî tiştan werdigirin, frekansa veguheztina vîdyoya wireless dikare were guheztin?

The frequencies of both the wireless video transmitter and the wireless video receiver can be modified. Bikarhêner pêdivî ye ku panelên veavakirina parametreyên zêde bikirin.
Lebê, bihesibînin ku dema ku mal têne şandin, amplifikator û antenna têkildar jixwe di nav rêzek diyarkirî de têne sabît kirin. Ger bikarhêner frekansa veguhêz eyar bike, the corresponding power amplifier, stefartî antenna, and receiver antenna should also be modified to the same frequency, û ev bikarhêner hewce ne ku amade bibin. Heke ne, ew ê bibe sedem ku frekansa transmittera vîdyoya bêtêl ji frekansa antenayê cuda be, resepsiyonê dijwar dike. Ji ber vê yekê ji kerema xwe berî ku hûn fermanê bidin frekansa rast a ku hûn hewce ne agahdar bikin.
Ger ew ji bo ewlehiyê an nepenîtiyê ye, you can use the encryption and decryption functions of the transmitter and receiver, ku dikare piştrast bike ku veguheztina vîdyoya we nepenî ye.
