A customer saw our real test video about the 2 watts Power Amplifier 27km trasmettitur u riċevitur tal-vidjo mingħajr fili fuq medda twila. 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 kilometri.

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 metru.

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 metru.

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. Fir-riċevitur, 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

L-ewwel, 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

It-tieni, if you want to support longer distances, we can achieve longer distances by changing different amplifiers. Pereżempju, 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

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