(The following are a few questions that customers often ask):
1. The following question is one of the most frequently asked but the most difficult to answer:
Question: How far and how far can you transmit in the open and barrier-free, but how far can it be transmitted in places with obstacles? How many floors can it pass? How many walls can I wear? How far can a 2000mW transmitter travel in the city? Why does it indicate that it can transmit 1000 meters but only 200 meters?
Answer: The transmission distance of different environments is completely different, because obstacles have high bottoms, walls are thick and thin, trees are dense, etc. For example, a 2000mW transmitter can transmit 1-1.5 kilometers in an open and barrier-free environment. In an open and barrier-free environment in the urban area, it can pass 500-800 meters, and in an environment with more buildings, it is possible to pass 200 meters or tens of meters, and it may be impossible to penetrate. But if you can choose to add an outdoor antenna in an environment with obstructions, try to put the outdoor antennas at both ends to the highest point, so that the antenna and the antenna can be open and can see each other, then the transmission distance at this time is ours The transmission distance indicated on the data.
2. How to test the wireless audio-visual transmission system that I just purchased?
Answer: A. First connect the camera (camera) to the power supply, connect the monitor (TV), and confirm that the camera (camera) and monitor (TV) can work normally;
B. Connect the transmitter, camera and power supply, connect the receiver, monitor and power supply, and then adjust the button on the receiver to select the channel. Make sure that the channel on the receiver is exactly the same as the channel on the transmitter; this way you can use the device normally. Equipment.
3. During the test, why do you say that you can pass several kilometers but you can’t pass several tens of meters during the test?
Answer: During the test, some people can only use a transformer on one side of a room to provide power to the transmitter due to power limitations, and to provide power to the receiver in another room not far away. In this way, It just happens to cause a great obstacle to transmission and reception, because the reinforced concrete structure of the building is a great obstacle to radio waves. When testing, please try to make the transmitter and receiver completely barrier-free. You can extend the connection line between the receiver and the monitor and add the connection line between the antenna and the transmitter, so that the antenna of the transmitter and the receiver If the antennas can see each other, the transmission distance of the device can be tested.
4. Why are there scrolling black bars on the monitor screen when using the wireless audio-visual transmission system?
Answer: This situation is usually caused by insufficient current provided by the transformer connected to the transmitter or receiver or the use of inferior transformers, just replace the transformer. It should be noted that the 12V/800mA transformers marked on the market are usually only about 300-400mA.
5. What is the clarity of your wireless audio-visual transmission system or why the transmitted image is blurred?
Answer: This system does not involve the sharpness of the image. The sharpness of the camera is what the sharpness is received. If the received image is blurry, please check the camera first to see if the camera focal length is wrong.
6. Will there be people around who use the same product to interfere with each other?
Answer: The number of channels of the wireless audio-visual transceiver system we provide is four, which can be selected according to the specific situation. Generally speaking, it will not be possible to stagger the same frequency point. If there are signals of the same frequency point around, they will interfere with each other.
7. When using your wireless audio-visual transceiver system, will others receive my signal?
Answer: If others use our company''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s wireless audio-visual transceiver system in the area near you, they may receive your transmission signal. If there are special needs, we can provide image/sound encrypted transmission services.
8. How many sets of your equipment can be used in the same area? In other words, how many points can be used?
Answer: Our wireless audio-visual transceiver system can provide 4 channels, which means that currently, 4 points can be used in the same area.
9. How many types of antennas are there? What is the role of each?
Answer: There are generally two types of antennas in wireless audio-visual transceiver systems, namely directional antennas and omnidirectional antennas. As the name implies, a directional antenna refers to transmitting a signal in a specific direction, while an omnidirectional antenna transmits a signal to the surroundings. In general, if it is a point-to-point transmission, a directional antenna is used; if it is a point-to-multipoint transmission, an omnidirectional antenna is used.
10. Is the external antenna used on the transmitter or the receiver?
Answer: Both are okay. It is usually used on the transmitter. Of course, the effect will be better if the transmitter and receiver are equipped with external antennas.
11. What model of machine needs an external antenna? How effective is the external antenna? Why after adding an external antenna, the transmission distance is closer or worse than using the original small antenna?
Answer: Under normal circumstances, wireless audio-visual transmitters with a transmitting power greater than 1000mW can be equipped with an external antenna;
Using an external antenna, in an open and barrier-free environment, the transmitter''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s transmission distance can be increased by 30%-70%;
If an external antenna is connected, the effect is not as good as the original small antenna. It may be that the external antenna is not connected properly. These connections include the connection between the connectors on the antenna, the connection between the antenna and the transmitter, especially with the transmitter. For the antenna connector connected to the machine, the wire core in the middle must be accurately inserted into the small hole in the transmitter antenna connector, otherwise, the external antenna will not work at all.
