With the development of the high-definition era, people are constantly pursuing clearer and more enjoyable visual experiences. In order for the wireless bridge to meet the requirements of high-definition and stable transmission, we need to consider the wireless bridge's receiving sensitivity, hardware, software, and bandwidth. The following describes how these factors affect the wireless bridge's transmission effect.
1. Wireless bridge receiving sensitivity:
The receiving sensitivity refers to the minimum signal receiving power of the antenna port required for the normal operation of the wireless monitoring equipment. Inter-system interference will lead to a decrease in the sensitivity of wireless monitoring equipment and affect the normal reception of signals. Therefore, the sensitivity criterion of wireless bridges is usually used as the protection criterion of the interfered system. Some wireless transmission equipment manufacturers have low signal sensitivity for equipment design. In order to make up for this shortcoming, they can obtain better results by increasing the transmission power. But the greater the device power, the greater the circuit current. If the device is in a high heating state for a long time, the stability will be lowered accordingly.
2. Wireless bridge hardware:
The hardware difference between cheap wireless bridges on the market and mid-to-high-end wireless bridges is very large. For some low-end wireless bridges on the market, the poor power amplifier uses large transmit power, but the transmission distance is short. The mid-to-high-end wireless bridges produced by Shenzhen Tengyuan Zhituo use imported power amplifiers, processors, memory, flash memories, power amplifiers and other components, which have very stable performance, small transmit power, long transmission distance, and very high net bandwidth. The entire circuit The board consumes low power and the line loss will be small.
3. Wireless bridge software:
The hardware of the wireless bridge is an important factor that determines the stability of the wireless bridge, but the software design of the wireless bridge cannot be ignored. The current wireless bridge has a built-in watchdog function, and the device hardware has a scheduled restart function. It has a search tool to facilitate finding and setting the device. Software upgrades and backups can be performed through the web window. The system has an automatic link detection function to prevent crashes and ensure the stable operation of the device. .
4. Bandwidth of wireless bridge:
Because the hardware, software design and sensitivity of each wireless bridge are different, the net bandwidth of the wireless bridge is also different. The net bandwidth of low-end wireless bridges on the market is very low. It is also a wireless bridge with a 5.8G frequency and 300M bandwidth. The net bandwidth of a low-end wireless bridge is generally only about 20M. Tengyuan Zhituo's wireless bridge can use multiple transmissions and one transmission mode. It can also use point-to-point transmission after multiple camera signals are concentrated. Although multiple camera signals are transmitted through a wireless bridge, whether it is image Neither stability nor fluency is affected.
Tengyuan Zhituo has rich experience in wireless bridge monitoring projects, and there are thousands of wireless bridge application cases across the country. If you have this need, our professional technicians will assist you in setting up the wireless monitoring system.
