ដើម្បីបង្ហាញឱ្យអតិថិជនរបស់យើងកាន់តែច្បាស់ពីចម្ងាយគាំទ្រជាក់ស្តែង និងប្រើប្រាស់ឥទ្ធិពលនៃ 2W PA 30km រូបភាពបញ្ជូន និងទទួលរូបភាពពីចម្ងាយ, យើងបានធ្វើតេស្តជាក់ស្តែងនាពេលថ្មីៗនេះ ហើយបានរកឃើញ Meisha Peak, ពីទីនេះទៅមាត់សមុទ្រណានអៅ, ចម្ងាយគឺ 27 គីឡូម៉ែត្រ. This site passes through Dapeng Bay, the line of sight is visible, and there are no obstructions. It just simulates the use of the transmitter in the air and the receiver on the ground.

How to choose the best long-range video transmitter and receiver?
Please consider the below points before you buy. Here are some tips for you.
1. ចម្ងាយការបញ្ជូន ពីឧបករណ៍បញ្ជូននិងអ្នកទទួល. The further the distance, the larger the power amplifier required; the larger the power amplifier, the higher the battery capacity requirement. ហេតុនេះហើយបានជា, you need to determine the wireless transmission distance according to your own project or drone.
2. LOS or NLOS, Is there any obstacle between the transmitter and receiver? All the transmission distances mentioned on this site are based on the LOS environment. If your use environment is NLOS, you need a larger power amplifier to have stronger diffraction and penetration capabilities. ដូចគ្នានេះផងដែរ, consider placing a relay repeater module in the middle.
3. One-way or two-way transmission type? One-way is like TV or radio, you can get the video or data at the receiver only, and two-way like mobile phones and the internet, you can get living video and send data or joystick control commands to the transmitter’s camera from the receiver side remotely. Two-way has a downlink and an uplink both.
4. ភី, អំភ្លីអំណាច, it is a signal enlarger, ឧទាហរណ៍, 1 វ៉ាត់, 2 វ៉ាត់, 5 វ៉ាត់, 10 វ៉ាត់, 20 វ៉ាត់, big PA support longer range and strong signal to Anti-jamming. When choosing a power amplifier, you also need to consider power consumption, which will also increase the capacity of the battery.
5. អង់តែន, A longer and bigger antenna will offer you better signal sensitivity. Omnidirectional FRP fiberglass antennas or automatic antenna tracking pan/tilts are recommended.
6. UART control, Do you need to send the AT command from the computer or portable tablet receiver via uart?

15. 27 KM long-range wireless video transmitter receiver Weight: 250 ក្រាម
One of our clients bought our 2W PA (អំភ្លីអំណាច) with 30km, up to 150km wireless video transmitter and receiver, but we can not find a 30km Line of sight place to test in our city, there are many high buildings. But luckily we found a place called Meishajian Peak, which is about 27 kilometers from the top of the mountain to the seaside.
About Meishajian, please check the below two links.
https://www.trip.com/travel-guide/attraction/shenzhen/meishajian-45198174/
Although the client chose a 2W-PA 30km transmission distance transceiver system, the test video is only 27km, So it is a 27 KM long-range wireless video transmitter-receiver.
Let us show you the transmitter and receiver first.
To show you clearly, we put the devices on one top and one bottom side for you.
There is two SMA antenna. ANT1 is the main antenna and works in transceiver mode. ANT2 is an auxiliary antenna that works in receive mode.
មាន 2 pieces of RJ45 ethernet input and power input. There is an Audio input and output connector, and the connector is three pieces of RS232 for UART data communication.
Before delivery, we take it out for testing and a live demo. It is hard to find a good place to test in our super large city, which needs 30km without obstacles. In this testing we have two teams, one team takes the IP camera and transmitter to the top of the mountain (Meishajian Peak), and another team takes the receiver and computer to the seaside (Nan’ao).
Where is the Air Unit Transmitter and Camera?
We put the transmitter, កាមេរ៉ា, and rechargeable battery on the rock.
On the map, we can see the distance measurement is 27.85km.(17.30 miles)
At the top of the mountain, the weather is bad and full of fog.
Here I use our last time demo video to show you our position and environment.
It was a sunny day, it was easy to watch the seaside.
Hope you see where are the transmitter and camera now.
That time we were at the top of the mountain to test another composite CVBS video transmitter COFDM-912T.
It also tested and passed 26km from the transmitter and receiver.
Today The set we tested is a long-range video data link system on the base of OFDM, which means the transmitter and receiver are the total same and support RJ45 IP web camera video input via ethernet connector.
If your camera has HDMI output, then it needs an extra HDMI encoder IP RJ45 output board, ដែលអាចអ៊ិនកូដវីដេអូ HDMI និងសញ្ញាអូឌីយ៉ូទៅជាទិន្នន័យឌីជីថលទៅឧបករណ៍បញ្ជូននេះ.
នៅអ្នកទទួល, វាអាចភ្ជាប់កុំព្យូទ័រឬ NVR របស់អ្នកដោយផ្ទាល់, We used a notebook computer monitor as the receiver screen, RTSP player, or VLC player to play the living video streaming from the transmitter and camera.
This model Networking mode support point-to-point and point-to-multipoint star network.
Point to point means one transmitter and one receiver, Point to multipoint means up to 6 cameras from the different transmitters and one receiver at the Security monitoring center.)
They are two-way broadband wireless video data audio links, the receiver can get the audio and video download, and it also can upload the data to the transmitter, ឧទាហរណ៍, some people need to control the PTZ camera via the joystick from the receiver.
Where is the Ground Unit Receiver and Computer (ground control station)?
At the receiver position, which is at the seaside, we use the two fiberglass antennae as the receiver’s antenna. Because the wireless video receiver supports RJ45 output, we can connect it by computer directly, with no need HDMI monitor.
The link and operation are very simple.
Now we will show you the video of the computer, it is from the computer recording screen software.
At the parameter of transmitter and receiver, there are two data in red, which shows the signal strength. Another import parameter shows the distance between the transmitter and the receiver.
This distance is calculated based on the time when the receiver sends some packets to the transmitter and receives their response from the transmitter.
Now we will show you the transmitter and receiver working details. The transmitter IP address is 192.168.1.12 and the receiver IP address is 192.168.1.11.
If you have any questions about our 27 KM long-range wireless video transmitter receiver, សូមទាក់ទងមកយើងខ្ញុំដោយសេរី. I will show you the details in the next video.
