Beijing security exhibition on six security electronics trends

On the morning of March 13, 2008 the 6th Beijing international community public safety products and technology exhibition in Beijing, China at the opening of the new Museum.

This exhibition consists of capital social law Committee Office, Beijing Municipal Public Security Bureau, co-hosted by. As the 2008 Spring's first major security exhibition, a total of more than 600 exhibitors, a total of 1 000. Visit the audience statistics for more than 5 million passengers. In addition to security vendors, some fire enterprise also participated in the exhibition. Impressive comparison is "safe city" and wireless monitoring and control products. From security equipment technology and engineering perspective can sum up out of the six major trends

1. traditional video surveillance is almost completely replaced by network monitoring, analog monitoring equipment basic exit visitors view.

In addition to network-based DVR, pay more attention to broadband and high-definition.

Wireless video surveillance, particularly in the compresses FODM wireless-based transmission was praised by many manufacturers, the price is higher than previous year dropped significantly. Work in the 800 m following until 300 MHz frequency bands for wireless video transmission, diffraction, equipment erection simple, low running cost, enter into the street with Lane, is particularly suitable in the highway, port, monitoring of real-time mobile community, is currently the preferred mobile monitoring.

2, infrared, laser, black light, night vision means has been widely used.

True enables the stars from the fog to until dark environment of video surveillance.

Black light or infrared, very suitable for close monitoring of non-visible, hidden under a very strong. Infrared and laser night vision effect mainly effective distance, but the image is blurred and can only display the outline, the higher the sensitivity. Such equipment is expensive, non-special occasion works hard to spread.

3, "safe city" concept as a new era of monitoring industry's hotspot.

3111 "projects" as the Guide for the construction of the "safe city" will greatly promote monitoring industry market.

In addition to networking, wireless, wired, the trend of high expansion lens, specifically developed for high-performance camera and optical lens has aroused the interest of visitors. The camera has a higher resolution, wide dynamic, ultra low illumination. New lens use spherical lens, large aperture, increasing the luminous flux rate, its automatic adjustment ability is also greatly improved. Generally used for high point monitoring and control of high multiple large lens made in products already have many of the significant drop in prices than in previous years.

Additionally since the "safe city" project social coverage, technical links, communications network is diversified, so also requires the development and construction of software platforms must be increased to a more complex Boda level.

4. car park intelligent management system is a big hit this year exhibition.

Manufacturers a lot, but the basic realization of independent research and development, in addition to platform software, ballot boxes, long-range reader, gates, etc., the basic realization of the independent research and development production.

Toll collection, automatic license plate recognition, image recognition, automatic intelligent parking car boot functionality had significant breakthroughs. In which not parking parking system adopts 900M UHF long-range reader, no parking card can direct traffic. Including parking sensors, parking directions system, hardware equipment, many can jointly develop production. And control based on upper software platform or shades of gray, some manufacturers added biometric technology such as a fingerprint, facial recognition, and others in the management of the practical aspects of the work.

5, security technology and smart home deeper integration.

To form a more comprehensive, more reliable, higher technology content of home security devices, involving anti gas gas, anti-theft, anti-Chuang, indoor electrical equipment safety, through the Internet and mobile communication can remotely receive real-time sound and image.

And you can realize remote control home related safety equipment and electric cookers, water heaters, air conditioners, electric curtains, etc.

6, coal mine safety monitoring of emergency network linkage facing great building space.

This type of display product hot spots still remain in the front sensor detection and level alarm level.

As the emergency response of new concepts, there are a lot of research and development space. In addition to mine, County, province to multi-level information dissemination, networking equipment structure and linkage, it must also be building decision-making software platform, also the construction of the head must be established to support the decision-making of the underlying database system, including the relief materials database, rescue teams database, medical resource databases, traffic conditions database, meteorological climate database, etc., are still to be invested huge human, material and financial resources.
