Cost reduction thermal imaging technology usher in the security of the spring

Into the security market, infrared thermal imagers are also constantly improving and innovating to meet the unique needs of security development. In addition to the cost, the pace of technology upgrades is also accelerating.

The popularity of prices has been limited by the price and maturity of use, and there has been no significant increase in the number of thermal imaging products.

The high cost has always been the biggest bottleneck for the development of thermal imaging cameras. The core of infrared thermal imager and imaging detector are not high in yield and difficult to manufacture. Only a few manufacturers in the world have mastered the detector's production technology and process, and the price of detectors has remained high. Because infrared imaging imaging band is infrared, therefore, the imaging lens material is not an ordinary glass, generally silicon, germanium and other semiconductor materials or zinc selenide, zinc sulfide and other materials. The prices of these materials are very expensive. Long-range thermal imagers have very long focal lengths and use more material, and the price of the lens can even exceed the price of the detector.

With the increase in sales volume and advancement in technology, thermal imager detectors are similar to visible light CCDs, and prices have been gradually declining. Some new infrared-free lens materials are also becoming practical. In the next few years, thermal imaging cameras will gradually reach the psychological expectations of the security industry. By then, there will be an explosive growth in the sales of thermal imaging cameras.

Networking + Intelligence Since the second half of last year, some traditional security companies have also begun to set foot in the field of thermal imaging and have launched thermal imaging network cameras. In November 2010, Axis broke the limits of thermal imaging technology in terms of cost and technology, and was the first to apply thermal imaging technology to network cameras. The Q1921 and Q1921-E thermal imaging network cameras from Axis have 384 x 288 resolution and an advanced image processor that not only improves the quality of surveillance, but also extends the detection range to 1,000 meters and to roads and tunnels. All-weather or perimeter monitoring is implemented at airports, airports, etc. In addition, these two thermal imaging network cameras also support important IP monitoring features such as H. 264 and Motion JPEG, audio, local storage, and Power over Ethernet. In addition, it also has intelligent video functions, such as Q1921-E has a tamper alarm and motion detection capabilities, and supports AXIS camera application platform, effectively meet the market segmentation and professional requirements.

In December of the same year, Hikvision also introduced a thermal imaging network camera. The thermal imaging network camera has good hardware compatibility and can transmit image signals over long distances without changing the basic structure of the existing network. At the same time, it also has good network compatibility, supports multiple interfaces and various types of protocols, and can run on various types of networks. In addition, it is also equipped with 8mm, 13mm, 20mm, 25mm, 40mm multiple focal length lens, and supports electric focusing and manual focusing, can effectively detect the target beyond three kilometers, in all kinds of extreme conditions can run normally and stable It provides solutions for various critical environmental security surveillance areas.

Talking about the difference between thermal imaging cameras and thermal imaging cameras, Hikvision's product director should report to the group that compared with traditional thermal imaging cameras, current thermal imaging network cameras can solve single work, installation and use in previous thermal imaging cameras. Need a lot of manpower, data can not be timely and effective return to the total, can not be online real-time monitoring and a series of issues, can do thermal imaging monitoring information into the entire network monitoring platform, to achieve no real all-weather large-scale monitoring. Through the network, thermal imaging images can be transmitted back to the monitoring center for analysis in real time. As an effective supplement to the visible light camera, it can provide full coverage of the monitoring object and monitoring range, and can be processed in a timely and accurate manner, greatly improving the real-time performance of the monitoring system. Effectiveness.

It is reported that PELCO and Bosch also keenly aware of the opportunities of thermal imaging cameras, have launched similar products.

The emergence of thermal imaging network cameras has also stimulated the improvement of thermal imager performance of traditional manufacturers. As of the end of February 2011, FLIR has released the latest E-Series thermal imager. The E-Series cameras have excellent infrared diagnostics and incorporate industry-leading innovations. This series of thermal imaging cameras have advanced thermal diagnostic capabilities and are designed and manufactured by plant equipment engineers, electrical engineers, and technicians in the heating, ventilation, and air conditioning (HVAC) industry, energy efficiency auditors, structural inspectors, and professional thermal imagers. Can help them find problems faster and more convenient, and through the top tools more effective transmission of problem data.

In addition, the E-Series thermal imagers use the industry’s first WiFi connection to connect to high-end products such as iPods, iphones and iPod touches without connecting to large notebooks, cables, or mobile switching SD cards.
