With the development of the Internet, the wireless communication industry is presenting a diversified new pattern, simultaneously opening up broader horizons for applications in the security industry. Wireless, high-definition, and integration have become important trends in the development of video surveillance. Wireless video surveillance has developed from the basic fixed-point transmission to the mobile and wireless automatic networking transmission mode.
For the hardware market, wireless technology is more and more mature, and the wireless video surveillance industry has entered a period of rapid development. Domestic wireless video surveillance products manufacturers are constantly developing and growing. Wireless monitoring equipment has become a hot spot in the field of technology consumption, and has a mature business model in technology application and market operation. With the popularity of high-definition surveillance cameras and the maturity of facility deployment capabilities, users have an increasing demand for intelligent mobile video surveillance solutions. At the same time, the demand for cloud monitoring solutions and the popularity of IP cameras also boosts the growth of the mobile wireless monitoring market.
Classification of wireless monitoring products
One, Mobile monitoring equipment is fixed or used to monitor non-fixed places through wireless transmission, such as collecting real-time images in law enforcement fields on the roof where a law enforcement vehicle monitoring camera is installed or through hand-held video monitoring cameras carried by law enforcement personnel, and then transmitting images to monitoring terminals through wireless networks.
Second, obtain images and places taken at fixed positions on fixed surveillance cameras through mobile devices, such as 4G mobile phone monitoring. At present, the main forms of mobile monitoring products are: mobile phone (or mobile terminal) monitoring, bus mobile monitoring, vehicle movement monitoring, law enforcement records, and mobile individual equipment.
A wireless monitoring system usually consists of four parts: wireless monitoring camera parts, transmission parts, control and recording parts and display parts. At present, products on the market often face the following problems:
First, the transmission signal interference
Signal interference has long been a significant factor troubling wireless surveillance data transmission. Wireless transmission relies on microwaves as a carrier, and video data signals are transmitted through attachment to wireless microwaves. During the transmission process, it is challenging to pre-detect interference from other sources.
Second, the transmission distance
At present, the distance of the most wireless transmission devices seen in the market is less than 50 kilometers, so relay mode should be used for long-distance transmission, and relay will weaken the transmission signal, which is not conducive to the high-definition video transmission of big data.
Third, equipment performance
With the booming development of the wireless transmission industry, various manufacturers seize the business opportunities and actively participate in the production of wireless surveillance products. This has resulted in a mixed market for wireless surveillance products, with varying product quality, making it challenging for users to choose products that meet their specific needs.
Wireless monitoring technology will be the key development direction in the future monitoring technology field by virtue of its own characteristics such as long transmission distance, convenient construction process and low input cost. Wireless monitoring enterprises must start from themselves, overcome technical difficulties and improve research and development ability, so as to get long-term development.
Smart security technology is maturing day by day, and the wireless monitoring market has broad prospects-China-exportsemi.com
