随着安防数字化、网络化、智能化发展,从2003年开始,一种被称作网络视频服务器即DVS的产品就一发不可收拾,在城市网络视频监控领域广泛应用,显现出巨大市场潜力。虽然DVS产品在安防监控系统中占有比例不大,但却是一款不可小视的产品。DVS随着网络监控的发展而兴起,主要实现模拟视音频信号的IP化传输。虽然DVS的技术含量不是太高,但却是一款划时代的产品。因为它迎合了网络监控的市场需求,致使所有生产DVR的企业趋之若鹜。在国内,百分百的DVR企业都生产DVS,因为两者核心技术都是图像压缩,DVR偏重于长时间的本地存储,而DVS则偏重于网络实时传输效果。实时传输查看视频监控图像是中国市场消费者的个性化需求,因而具有中国特色的DVS既有巨大的市场空间,又不得不受制于DVR囚徒的困境。有业内专家指出,虽然两者的功能各有侧重点,但技术上、功能上的互补性很强,如果在技术上有较大突破的话,DVS和DVR可以合到一起,使得网络监控系统更加简单化,传输、存储、报警于一体也许是DVS今后重点发展的方向。
With the development of digital security, networked and intelligent development, since 2003, a product called DVS, an online video server, is out of control and has been widely applied in the field of urban network video surveillance. It shows great market potential. Although DVS products occupy a small proportion of security monitoring system, but it is a product not to be overlooked. DVS with the development of network monitoring and the rise of the main realization of analog video and audio signal transmission IP. Although the technical content of DVS is not too high, it is an epoch-making product. Because it caters to the market demand for network monitoring, resulting in all the business of producing DVR rush. Domestically, 100% of DVR companies produce DVS because the core technologies of both are image compression. DVRs favor long-term local storage, while DVSs emphasize network real-time transmission. Real-time transmission View video surveillance image is the individual needs of consumers in the Chinese market, so DVS with Chinese characteristics have huge market space, but also have to be subject to the dilemma of DVR prisoners. Some industry experts pointed out that although the two functions have their own focus, but the technical, functional complementarity is strong, if there is a major technical breakthrough, DVS and DVR can be together to make the network monitoring system more Simplification, transmission, storage, alarm in one may be DVS future focus on the development direction.
