Video surveillance system development history

In 1951, some companies, mainly American Radio Corporation, began to develop video recorders and video tapes. In December 1953, the Pentax Roussby Institute took the lead in launching the color multi-track video tape and its playback system by using the multi-track method, but the broadcast picture was relatively blurry and could not be put into use immediately. In April 1956, the American Ampere Company took the lead in developing the world’s first practical commercial video tape recorder and named it “Ampere VRX-1000”.

In 1957, Panasonic developed the first electronic picture tube camera, and then introduced the 1-inch camera WV-010 in 1962, the three-color tube camera in 1970, the CCD color camera in 1985, and the WJ-FS50 video recorder in 1992. In 2001, the WJ-HD500 16-channel hard disk video recorder was launched. For nearly 40 years, Panasonic has been at the forefront of the security monitoring technology revolution, with super dynamic technology, automatic dark zone compensation technology, automatic rear focus adjustment technology, and lock tracking technology. , Intelligent analysis technology has led the development of the industry all the way. When it comes to video surveillance, there is another company that cannot be avoided that is Sony, and Sony’s core influence in the field of video surveillance comes from CCD.

In 1969, the Bell Telephone Research Institute in the United States invented the CCD. It is a magician who converts “light” information into “electric” information. In the Sony development team at that time, a young man named Yue Zhi Chengzhi was very interested in CCD and began his research on CCD. However, because this research is still far from commercialization, the more intelligent it becomes, the more it can only do research silently alone. In 1973, Iwama, the then-Vice President of Sony Corporation, a uniquely discerning operator discovered Ochi’s research and said with excitement: “This should be the subject of Sony’s semiconductor department! Okay, let’s do it. Cultivate this seedling!” At that time, Ochi only realized a rough “S” drawn with 64 pixels. However, Iwama put a puzzling sentence on Yue Zhi: “Use CCD to make a camera.” After that, the booming surveillance industry was born.

In November 1973, CCD finally set up a project in Sony, and established a development team centered on Yuezhi. In March 1978, Sony manufactured an integrated block that was considered “impossible” with 110,000 components on a circuit board, creating the world’s first CCD color camera. In 1985, the first 8mm camera “CCD-V8” was born. Afterwards, the development and launch of CCD were on track. Sony introduced HAD sensors in the early 1980s, ON-CHIP MICRO LENS in the late 1980s, SUPER HAD CCDs in the mid-1990s, NEW STRUCTURE CCDs in 1998, and EXVIEW HAD CCDs in 1999. CCD has also been widely used in the field of video surveillance.

CMOS image sensors and CCD image sensors appeared almost simultaneously in the 1960s. After 1990, the passive pixel CMOS image sensor entered the market as the first-generation CMOS image sensor, and then gradually became the mainstream sensor solution for cameras. This is something later.

In 1996, Axis launched the world’s first network camera. In 2008, Axis, together with Bosch and Sony, announced the establishment of ONVIF (Open Network Video Interface Forum), and jointly formulated open industry standards based on the principles of openness and openness, which promoted the development and popularization of network video surveillance systems. In October 2011, GoTV released the first video summary system; in May 2016, Jiadu Technology launched the “Video Cloud +” large application platform V1.0; in March 2018, Yuncong Technology officially released the high-performance AI camera “torch eye” smart face recognition camera.

When it comes to the development history of video surveillance, there are two other companies that have come from behind to mention, that is, China’s Hikvision and Dahua. According to the Nikkei (Chinese version: Nikkei Chinese website), the 2017 “Survey on Global Market Share of Major Goods and Services” was compiled. Among the 71 categories included in the survey, the products of Chinese companies have the largest market share in 9 categories. Among them, the number one camera, Hikvision, has a share of 31.3%, and the second number Dahua has a share of 11.8%. The two companies have a combined share of 43.1%, which means that almost half of the world’s cameras are owned by these two companies. made.

Hikvision was founded in 2001. In 2002, it released the DS-4000M video and audio compression card and DS-8000 network hard disk video recorder, which started Hikvision’s video surveillance journey. This journey lasted 16 years. After that, in 2003, the industry first implemented the H.264 algorithm on the DSP, and based on the H.264 algorithm, it was the first to launch the DS-4000H board with independent intellectual property rights and the network hard disk video recorder DS-8000M, opening a new era of H.264. In 2007, the first infrared barrel series camera was launched. With this camera, it successfully broke into the Chinese camera market and quickly became one of the mainstream infrared camera brands in the market, realizing the leap from DVR to camera. In 2009, the Public Security Industry Solutions Business Department was formally established, and the iVMS-8200 Safe City Comprehensive Application Management Platform product was released, successfully transforming from a product supplier to an overall solution provider. In 2012, the launch of the first civilian product-“Xiaoweishi” marked the beginning of the industry application of video surveillance to small and micro enterprises and home micro-video applications. In 2015, based on the concept of “Smart Security 2.0”, cross-border products represented by industrial cameras and drones were released to promote security from safety to efficiency to benefit. In 2017, Haikang released the AI ​​Cloud cloud edge integration strategy to march towards AI and promote the development of the industry.

Dahua Co., Ltd. was founded in 1993 and established a joint-stock company in 2001. In the early days, Dahua mainly produced hard disk video recorders. At that time, the DVR products on the market were all board-type, and all the core technologies depended on imports. Not only was the price high, ordinary consumers could not afford it, but also caused the long-term impact of national enterprises. suppress. In 2002, Dahua launched the industry’s first self-developed 8-channel audio and video synchronous embedded DVR, creating the first brand of embedded DVR, and making security begin to bloom everywhere. Since then, Dahua has continued to focus on video surveillance technology and has gradually grown to become the second largest company in the world in terms of camera market share. There are several important milestones in the development history of Dahua: Going overseas in 2003, launching the intelligent transportation all-in-one machine in 2007, becoming the de facto standard of China’s electronic police, focusing on image processing technology and network technology in 2008, and introducing CMOS in 2010 Technology and launched the high-definition high-power movement. In 2011, the concept of “cloud” was introduced. In 2012, HDCVI technology was adopted by the HDcctv alliance as the first international standard in China’s security industry. In 2014, the Le Orange brand was established, entered the civilian market, and established as the first in the United States. An overseas branch company, established an artificial intelligence research institute in 2016, and launched a cloud ecology and smart future strategy of “full intelligence, full computing, full perception, and full ecology”. It is expected that in the future, with video capabilities as the core and artificial intelligence as the backing, it will provide smart IoT solutions and operational services, and actively deploy smart video surveillance systems.
