Wireless image transmission is short for wireless image transmission system. And wireless image transmission equipment is often used for real-time transmission of video signals on drones, robots, cameras and other equipment. It has important applications in the modern wireless field.
For a long time, the short transmission distance has always been an important factor in the development of wireless image transmission equipment. However, with the continuous improvement of wireless technology, the transmission distance of wireless image transmission equipment is getting farther and farther. Today we will understand how wireless image transmission equipment can transmit farther.
1. Interface
Transmitter: Use a standard cable camera or other video equipment SDI/HDMI output port to connect with the transmitter SDI/HDMI port, confirm that the input signal format is within the format range supported by the image transmission device;
Receiver: Connect the SDI/HDMI output port of the receiver to the input port of the monitor.
Special attention is paid to the fact that if the cable quality is not good, it will directly affect the stability of the signal, so it is very important to choose a good quality transmission cable.
2. Power supply
Generally speaking, wireless image transmission equipment has two power supply modes: battery power supply and DC interface power supply. The power supply voltage range is generally 6.5V-36V, which can be used with movie machines.
3. Antenna
Different antennas are opened at different angles during use to avoid coupling and interference between the antennas, so that the wireless image transmission distance can reach an ideal state.
4. Frequency band selection
Wireless image transmission transmitter and receiver to ensure the process of working on the same frequency. The selection knob can be adjusted by the frequency of the communication channel. If the sending and receiving are not at the same frequency point, the video signal cannot be sent normally.
5. Use multiple groups at the same time
In the same environment, transmit multiple groups of videos at the same time (recommended up to 4 groups). The frequency points of the wireless transceivers in each group need to be separated as much as possible.
If the above points are well grasped, the transmission distance of wireless image transmission equipment will be longer. Tengyuan Zhituo wireless image transmission equipment has the advantages of long transmission distance, strong anti-interference ability, and stable transmission signal. It has been applied in many large and medium-sized wireless transmission projects and has been well received.
