With the development of monitoring in the direction of high-definition, and the integration of IT technology, the monitoring technology has been transformed from the original single analog monitoring to the analog and digital surveillance coexistence, and the HD high-speed dome is slowly becoming known to everyone.
The first 'high-definition' integration makes HD high-speed dome products high in price, and can only be limited to high-risk and high-security industrial markets in applications, such as safe cities, airports, ports and other high-end areas, in civil security The market has not been correspondingly developed. However, with the rapid development of monitoring and industrialization, high-definition monitoring technology continues to be introduced, which further accelerates the promotion of HD high-speed ball market applications. Tianhui Tianye Weiye Digital Technology Co., Ltd. Product Manager Guo Hui said: 'The reason why the high-speed high-speed ball gradually shine in the market, precisely because the market put forward the demand for high-definition monitoring, compared to analog high-speed ball, high-speed high-speed ball with High-definition picture, wider coverage, easy-to-expand performance, intelligent analysis and other functions can meet the needs of market users. '
Compared with similar imported products imported from abroad, domestic HD high-speed domes have certain advantages in terms of price, and the overall market has evolved from the original foreign manufacturers 'dominated' to the current 'sharing' situation. For a time, the high-speed high-speed ball continued to decline in price, which further provided powerful conditions for the development of the civilian security market. 'At present, the high-definition speed dome market is dominated by domestic manufacturers. In terms of price, domestic manufacturers have certain advantages over foreign manufacturers. The rise of domestic manufacturers has led to a substantial reduction in product prices and promote the further development of China's security industry. 'Feng Yuyu, Business Director of Liling Enterprise Guangzhou Mingyou Electronics Co., Ltd. added.
