Glimmer and thermal imaging technology are popular in security industry

Glimmer and thermal imaging technology are gradually being sought after by the security industry applications As we all know, with the development of optoelectronic, microelectronics, network communications, digital video, multimedia technology and sensor technology, Security monitoring technology is also from the traditional analog to the highly integrated digital, intelligent, network-based. With the increase in market demand, modern high-tech are almost utilized in security monitoring systems or will be used. In which low light level technology and infrared thermal imaging technology have also been applied in the security system. Night vision surveillance technology utilizes the Electric vacuum and electro-optical technology to implement the conversion of photon image - electronic images - visual video image. During the conversion process through electronic image enhancement technology, to achieve the visual enhancement of the image, thus achieving the faint light of a night vision. While the thermal imaging technology is a kind of passive infrared night vision technology, ordinary infrared monitoring technology is active infrared night vision technology. The thermal imaging technology forms the image with different infrared thermal radiation intensity of different parts of natural objects. It discovers the target with the target and background, or the temperature differences of various parts or heat radiation difference of the target. Because the technology did not vary with the peripheral illumination conditions change, so can be in a day and night, and even the fog, rain and other harsh environments, to provide a video image. But it cannot realize more remote monitoring, and monitoring picture can only tell whether there is a suspicious person enters, and not being able to see clearly the face and appearance. Ordinary infrared camera is a kind of active infrared technology, it’s a night vision technology through the active infrared emission, using target reflected infrared light to achieve camera monitor. With the application of the third generation of infrared array technology, effectiveness of active infrared monitor has improved a lot. The better are the product quality and life expectancy. And the manufacturing process is less demanding, the cost is low, it has a broad application prospects. Night vision and thermal imaging technology in practical applications are somewhat similar. Cameras of these two technologies are utilized in night and special surveillance places such as military, criminal investigation, drug smuggling, defend and so on which have some demands about concealment. The two devices are appropriate in this type of monitoring sites. The night vision camera is to monitor the scene by enhance electronic image generated by week natural light to the video image can be effectively monitored. And thermal imaging technology is to work with the principal that object higher than the absolute temperature zero ( - 273 degrees C) is able to radiate infrared ray. Due to a variety of objects in different infrared thermal radiation intensity, people, animals, scenes, all objects can be clearly observed and don’t influenced by the smoke，frog, grass and other obstacles, it can work both day and night. Infrared ip cameras we often talked about are considered active infrared. That is, infrared beam to fill light, exposure objectives unrestricted, the all black case can also be used, good and affordable, but the fill light distance limited, concealment is not strong, vulnerable effected by the weather and other factors, and there are big difference in reflection of various target to infrared light. These will affect the image quality. For now, the infrared thermal imaging technology is more widely used in security than the low light level imaging technology. The specific applications of infrared thermal imaging are as follows: 1. Target surveillance at night and under adverse weather conditions 2. Fire monitoring 3. Identification of camouflaged and concealed targets 4. The application of infrared thermal imaging inspection and quarantine
