安全防范系统前端的图像传感器和防盗、防火探测器主要是光电成像器件和光电探测器件,其终端和不可见光源等又是其电光转换器件与发光器件。还有传输图像信息的光纤、红外光传输、夜视以及光电图像的处理、识别与跟踪系统等光电技术,均是安防技术的核心。因此,安防技术,实际是光电技术在安全技术防范系统中的一门应用科学技术。但是,过去与现在从事安防技术的大多是一些电子技术与计算机技术等专业的工作人员,他们缺乏光电技术的基本理论知识,因而在说话、写文章,甚至未经严格审查的产品说明与书籍中,都出现这样那样的基本概念混淆与错误。本文就安防从业人员经常碰到的30个问题一一展开说明,希望与大家共同分享。
Security system front-end image sensor and anti-theft, fire detectors are mainly photoelectric imaging devices and photodetection devices, and its terminal and invisible light source is its electro-optical conversion devices and light-emitting devices. There are optical fiber transmission of image information, infrared light transmission, night vision and photoelectric image processing, identification and tracking systems and other optoelectronic technology, security technology are the core. Therefore, the security technology, is actually a photoelectric technology in the security technology to prevent a system of applied science and technology. However, most of the security technologies in the past and present are professional staff members such as electronic technology and computer technology who lack basic theoretical knowledge of optoelectronic technology. Therefore, in product descriptions and books that are spoken or written, or even not scrutinized, , There have been such a basic concept of confusion and error. This article on the security practitioners often encountered one by one to explain the 30 questions, I hope to share with you.
