基础案例 | 安装监控，你最行！
安防监控系统是应用光纤、同轴电缆或微波在其闭合的环路内传输视频信号，并从摄像到图像显示和记录构成独立完整的系统。它能实时、形象、真实地反映被监控对象，不但极大地延长了人眼的观察距离，而且扩大了人眼的机能，它可以在恶劣的环境下代替人工进行长时间监视，让人能够看到被监视现场的实际发生的一切情况，并通过录像机记录下来。同时报警系统设备对非法入侵进行报警，产生的报警信号输入报警主机，报警主机触发监控系统录像并记录。安防监控系统是一门被人们日益重视的新兴专业，就发展看，应用普及越来越广，科技含量越来越高。
The security monitoring system is a video transmission system which uses optical fiber, coaxial cable or microwave to transmit video signals in its closed loop, and form an independent and complete system from video to image display and record. It can real-time image, and truly reflect the object being monitored, not only greatly extends the human eye observation distance, and expand the function of the human eye, it can be in the bad environment instead of artificial long time monitoring, people can see all monitored the actual scene, and through video recording. At the same time, the alarm system equipment alarm the illegal invasion, the alarm signal produced by the alarm host, the alarm host triggers the monitoring system to record and record. Security monitoring system is a new profession which is being paid more and more attention by people. As far as the development is concerned, the application and popularization are becoming more and more widely, and the content of science and technology is getting higher and higher.
我国人口数量大，随着我国经济发展与人民生活水平日益提高，居民消费水平的提高将带动安防监控行业的发展，因此我国安防监控市场是一个极具潜力的市场，国内安防监控产品存在较大的发展机会。小编在某销售网站上抓取了1624条安防监控产品数据，试图分析影响评价的因素。
The number of China's population, with China's economic development and the improvement of people's living level, raise the level of consumer spending will drive the development of the security monitoring industry, so the security monitoring market in China is a very potential market, domestic security monitoring products have great development opportunities. The small editor grabbed 1624 security monitoring products data on a sales website and tried to analyze the factors affecting the evaluation.
