Anti-theft Alarm Development History
- Jan 07, 2019 -

The burglar alarm product is the earliest security product to enter the Chinese market. Therefore, the burglar alarm product has become the earliest area for Chinese security product manufacturers. The application of anti-theft alarm products in China began in the early 1960s. The anti-theft alarm system of the Beijing Municipal Public Security Bureau's technical research system was originally applied to the Palace Museum. The voices issued by criminals were used as alarm signals, and the staff on duty heard the sounds. Take appropriate measures.

With the development of science and technology, in 1982, the Ministry of Public Security and the First Institute of the Ministry of Public Security installed active infrared, passive infrared, microwave, ultrasonic, voice control and other anti-theft detectors for various exhibition halls of the Forbidden City according to the development of the burglar alarm technology at that time. The burglar alarm system has formed a variety of detection methods, and the burglar alarm technology has been raised to a new level.

After 1984, the security industry entered the stage of popularization and improvement in China, and it developed rapidly. In particular, in order to strengthen the security and protection work for the 35th anniversary of the National Day in 84 years, a TV monitoring project was established in Tiananmen Square. Since then, TV monitoring technology has entered the burglar alarm system and urban traffic safety control, which has improved the system function.

In 1992, in the case of cultural relics in Kaifeng, criminals used pre-tested anti-techniques to cover multiple passive infrared detectors, causing them to lose their alarm function, thus making theft successful. This incident made people aware of security precautions. The loopholes and deficiencies have greatly promoted the development of perimeter defense and the detection of anti-occlusion functions, and also promoted the development of intrusion detector technology.

In 1996, the Beijing Municipal Public Security Bureau began to launch a regional networked alarm network for the key units and places in the financial industry, marking the beginning of the commercialization application era of burglar alarms.

The domestic burglar alarm industry has really achieved rapid development. After 2000, some manufacturers in Shenzhen, Fujian, Zhejiang and Henan have grown rapidly, and the scale of investment and corporate strength are rapidly developing and growing. From the initial analog signal technology to microwave technology, the product has evolved into infrared digital pulse technology, which is constantly improving and perfecting in terms of sensitivity, resolution, detection accuracy, and performance.
