With the continuous development of science and technology, the security industry is also constantly developing, and various security products are pouring into the market like spring bamboo shoots. The same is true for the wireless surveillance industry. Due to the continuous development of high-definition signals, analog cameras have been eliminated. Therefore, analog wireless monitoring devices have basically withdrawn from the market, and wireless bridges have become the main force in the wireless market. At present, the market for wireless bridges is very chaotic, and products of various price points are available. However, the price of a piece of goods, from the parameters and product appearance is no way to see the quality of the product, the same parameters of the wireless bridge, we must judge the wireless from the hardware, software, receiving sensitivity and the wireless bridge's net bandwidth The quality and stability of the bridge, Shenzhen Lai'an Technology Xiaobian to briefly introduce:
1, the difference between wireless bridge hardware:
The difference between the cheap wireless bridges on the market and the hardware of the high-end wireless bridges is very large. For some poor power amplifiers used in some low-end wireless bridges on the market, the transmission power is large, but the transmission distance is close. The high-end wireless bridges produced by Shenzhen Lai'an Technology use imported power amplifiers, processors, memory, flash memory, power amplifiers and other components. The performance is very stable, the transmission power is small, the transmission distance is long, and the net bandwidth is very high. The whole circuit board Low power consumption will result in low line losses.
2, the difference between wireless bridge software:
The hardware of the wireless bridge is an important factor in determining the stability of the wireless bridge. However, the software design of the wireless bridge cannot be ignored. The software of Shenzhen Laian Technology Wireless Bridge is very mature. The wireless bridge built by our company has more than ten years of experience. It has thousands of projects of large projects. We have continuously updated and improved our products for more than ten years. Products, continuous optimization of software and functions, currently our wireless bridge built-in watchdog function, device hardware timing restart function, with search tools to easily find and set up devices, software upgrades and backups can be done through the web window, the system has automatic link detection Function, put an end to the crash, and ensure the stable operation of the equipment.
3. Wireless bridge receiving sensitivity:
A stable wireless bridge not only uses good components for hardware, but software design is also very important. Another important factor in determining a wireless bridge is reception sensitivity. The receiving sensitivity refers to the minimum signal receiving power of the antenna port required for the wireless monitoring device to work normally. Inter-system interference can cause the sensitivity of the wireless monitoring device to decrease, affecting the normal reception of the signal. Therefore, the wireless bridge sensitivity criterion is usually used as the protection criterion of the interfered system. The receiving sensitivity of a wireless bridge is similar to that of human hearing. In everyday environments, the better the ability of a person with better hearing to capture sound is. Similarly, the higher the wireless bridge receiving sensitivity, the stronger the ability to capture weak signals. If the received signal energy is less than its receiving sensitivity, the wireless bridge will not receive any data. Some wireless transmission equipment manufacturers do not have high sensitivity for equipment design expenditure signals. In order to make up for this defect, a better effect is obtained by increasing the transmission power. But we know that the higher the power of the device, the larger the circuit current. The heat is high, and if the equipment is in a high heat state for a long time, the stability will be correspondingly low.
4, the bandwidth of the wireless bridge
Since the hardware and software design and sensitivity of each wireless bridge are different, the net bandwidth of the wireless bridge is also different. The net bandwidth of the low-end wireless bridge in the market is very low. It is also a wireless bridge with a bandwidth of 5.8G and 300M. The net bandwidth of the low-end wireless bridge is generally only about 20M. For the Shenzhen Lai'an technology industrial-grade wireless bridge, for example, the LA-5839S with 5.8G frequency and 300M bandwidth is a wireless bridge. It adopts the new AR9342 processor, which is stable in operation and high in reliability, ensuring stable operation in high temperature or low temperature environment. . The dual-channel RF output is 26dbm (400MW), and the LA-5839S system integrates 5.8G and 18dbi dual-polarized antennas. The point-to-point design has a transmission distance of 5 kilometers, a point-to-multipoint transmission distance of 3 kilometers, and a bidirectional rate of up to 100M.
It can be seen that the wireless bandwidth of Shenzhen Laian Technology is very large, so our company's wireless bridge will not be affected by the bandwidth in the harsh environment, and will not delay, image instability, etc. like the low-end wireless bridge. phenomenon. The wireless bridge of our company is not like the one-to-one transmission mode of the low-end wireless bridge. We can use the transmission mode of multiple transmissions and one transmission. It can also use the point-to-point transmission mode after multiple camera signals are concentrated, although many The camera signal is transmitted through a wireless bridge, and the stability and smoothness of the image will not be affected.
Shenzhen Lai'an Technology has a wealth of experience in wireless monitoring projects. Our company has thousands of wireless monitoring projects in the country. In the initial stage of building a wireless monitoring system, we can design a wireless monitoring solution for you free of charge. We have professional technicians to help you complete the construction of the wireless monitoring system.
Transparent Gauge Glass
Transparent gauge glass, also called transparent Sight Glass, transparent level glass and transparent Level Gauge, is usually made of borosilicate glass and aluminosilicate glass. The glass is manufactured into the strip shape and used in boiler or some instruments for observing the liquid level.
It can be used with all media at service conditions up to 6MPa and temperatures up to 430 degrees centigrade.
