Transmissor i receptor d'àudio de dades de vídeo sense fil, De doble sentit, Download-Upload

A customer saw our real test video about the 2 watts Amplificador de potència Transmissor i receptor de vídeo sense fil de llarg abast de 27 km. 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 quilòmetres.

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 metres.

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 metres.

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, IDE, 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. Al receptor, 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

Primer, 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

Second, if you want to support longer distances, we can achieve longer distances by changing different amplifiers. Per exemple, 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

Tercer, what is the concept of supporting up to 150 quilòmetres? It is equivalent to 93 milles. The UK is separated from Europe by the English Channel, and its width is only 35 quilòmetres, això és, 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 + Amplificador de potència

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 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. Pel que fa al transmissor de vídeo, quines són les freqüències disponibles?

There are three frequencies to choose from 800Mhz, 1.2G, i 2.4G.
Però no hi ha un amplificador de potència de 10 W per a 150 km a 2,4 Ghz. So if the buyer wants to support a 150km transmission distance, només es poden triar 800Mhz i 1,2G.

3. Pots fer un vídeo de prova perquè el vegi abans de l'enviament?

És clar, també entenem que els transmissors i receptors de transmissió de vídeo sense fil són molt cars. Esteu lluny de la fàbrica de la Xina. i esperem que els productes que rebeu siguin aptes per al millor rendiment.

Si es presta especial atenció a un paràmetre o funció específic, podem fer alguns vídeos de prova basats en les funcions que vulgueu veure, si us plau, no dubteu a contactar amb nosaltres. It won’t be shipped to you directly without your approval. Just like today, I tested and show the video to my client.

4. Puc utilitzar un cable de RF de 3 metres des del transmissor a l'antena??

Pel que fa al cable de RF, our engineer doesn’t recommend that you used so long. Hi haurà una reducció de 0,5 dB per a un cable de RF d'un metre. Per 3 cable de RF del mesurador, la força del senyal es reduirà en 1,5 dB.

5. It seems that your transmitter is supporting an IP camera, but my video source camera is HDMI or SDI video output, Com puc utilitzar aquest transmissor i receptor?

si, l'entrada de vídeo predeterminada és IP RJ45 ethernet pot, if your camera is HDMI or SDI or AHD, només més una petita caixa codificadora per resoldre aquest problema, this encoder box will output IP living stream to the transmitter.

6. Quins tipus de port d'entrada de vídeo té el vostre transmissor de vídeo sense fil?

Els nostres transmissors de vídeo sense fil tenen aquest tipus d'interfícies d'entrada de vídeo: HDMI 1080P i 4K HDMI, CVBS compost, IDE, AHD, Ethernet IP, and BNC, or tell us what type you need, and our engineer will modify it to meet your demand.

7. Quina és la distància de transmissió compatible amb el vostre transmissor de vídeo sense fil??

La nostra distància de transmissió es pot ajustar afegint amplificadors de potència. Al present, the main ones are 15km, 30km, 50km, 80km, 100km, i 150 km, que depenen de les necessitats dels clients.
És clar, the transmission distances listed above are all within LOS the line-of-sight range. Si hi ha obstacles entre l'emissor i el receptor, NLOS (la no línia de visió), la distància de transmissió es redueix molt, només 1 km o 2 km, depenent del nombre d'obstacles intermedis i de l'entorn sense fil local.

8. Què és unidireccional o bidireccional? Simples vs semidúplex, full-duplex

One-way means, Només podem transmetre i descarregar vídeo o dades des del transmissor de vídeo sense fil al receptor en una direcció, i no podem pujar vídeo o dades del receptor al transmissor. Aquest tipus també s'anomena simplex.
Two-way means that, no només podem descarregar vídeo o dades del nostre transmissor sense fil al receptor, però també podem pujar el vídeo o les dades del receptor al transmissor. Això és molt adequat per operar drons. 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. Això pot funcionar simultàniament. This type is also named half-duplex or full-duplex.

9. El vostre transmissor de vídeo HDMI admet el xifratge i el desxifrat del receptor?

Most Wireless video transmitters now support AES128 or AES256 bit encryption and decryption, depenent del model que trieu. Si us plau, poseu-vos en contacte amb nosaltres per verificar.

10. Es pot modificar la freqüència del transmissor de vídeo sense fil després que els usuaris habituals rebin la mercaderia?

The frequencies of both the wireless video transmitter and the wireless video receiver can be modified. Els usuaris han de comprar plaques de configuració de paràmetres addicionals.
malgrat això, tenint en compte que l'amplificador de potència i l'antena corresponents ja estan fixats dins d'un cert rang quan s'envien les mercaderies. Si l'usuari ajusta la freqüència del transmissor, the corresponding power amplifier, transmissor de l'antena, and receiver antenna should also be modified to the same frequency, i aquests usuaris han d'estar preparats. Sinó, farà que la freqüència del transmissor de vídeo sense fil sigui diferent de la freqüència de l'antena, dificultant la recepció. Per tant, assegureu-vos d'informar la freqüència correcta que necessiteu abans de fer una comanda.
Si és per seguretat o confidencialitat, you can use the encryption and decryption functions of the transmitter and receiver, que pot garantir que la transmissió de vídeo sigui privada.

11. He vist que el teu model s'assembla molt a les meves necessitats, però he de modificar un dels paràmetres, és això possible?

si, all our product parameters can be customized according to customersneeds. Si tens una petició especial, si us plau fes-nos-ho saber.

12. Què he de fer si el meu receptor de vídeo sense fil mostra un senyal feble?

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. Només puc comprar mòduls dels transmissors i amplificadors?? Vull muntar-los al meu equip.

Podem, és clar, supply wireless video transmitter modules and power amplifiers.
Per a la primera prova de mostra, Us recomano que compreu tot el conjunt de productes perquè els nostres enginyers han optimitzat els paràmetres per aconseguir el millor rendiment.
