Application advantages of laser cameras compared with ordinary infrared cameras

The laser camera is equipped with a laser light source on the surveillance camera. The laser light adopts the spot average enhancement technology and the spot automatic focusing technology. Laser night vision technology is one of the ways to complete long-distance night vision monitoring. Because the laser has the characteristics of high brightness, good coherence, good monochromaticity, good directionality, long life and CCD's sensitivity to its wavelength is greater than that of LED. It is determined that the laser can reflect a farther distance, and the light intensity is much stronger than that of conventional light sources. Compared with ordinary infrared cameras, the characteristics and advantages of laser cameras are mainly manifested in several aspects: The first is the long monitoring interval. Laser cameras can be divided into short-distance laser cameras (effective night vision monitoring distance is 100-500 meters) and medium-distance laser cameras (effective night vision monitoring distance is 500-1000 meters) and long-distance laser cameras (effective night vision monitoring distance is 500-1000 meters) according to the monitoring interval. The monitoring interval is 1000-3000 meters). The second is that the focal length of the lens can be automatically adjusted, and the clarity is greatly improved. Although infrared cameras can see images at night, they often cannot see faces. In addition, the monitoring interval of ordinary infrared cameras is limited, which is very regrettable in some places that require strict security monitoring. The laser camera can ignore the intensity of light. With laser infrared components and ultra-low illumination light components, the camera can achieve high-definition night vision at close range and close range in a completely dark environment, while ensuring clear imaging. Many laser cameras have certain intelligent functions, which can automatically adjust the length of the lens according to the distance and moving speed of the object in order to provide clear image quality. The third is longer life, laser surveillance cameras are 3 times longer than ordinary infrared cameras. This is an increasingly prominent advantage in an environment that requires 24-hour monitoring. The fourth is its low-carbon green function. Traditional infrared cameras dissipate a lot of heat, which not only consumes more power, but also the heat cannot be distributed in the fuselage, resulting in overheating of the fuselage, which seriously affects the life of the electronic components in the camera, while the laser camera does not have this. hidden danger. Technical characteristics and optional application of laser cameras Laser night vision technology has been presented in China for nearly ten years. It belongs to a kind of active infrared night vision technology. For the purpose, its wavelengths are mostly 808, 940 and 980 nm, which belong to near-infrared light. The laser night vision monitoring system uses a night vision lens with high light intensity to receive the target reflected light for imaging, and then uses a low-illumination CCD camera to collect and output the image. The lighting system, imaging lens, and camera, as the central components of the system, cooperate with each other, and any bottleneck in any link will cause the entire system to fail to achieve the desired effect. At present, the common laser night vision integrated cameras and laser night vision split cameras in the market all use opto-mechanical integration and integration technology, which can clearly monitor the target activities within a range of 100-3000 meters in the dark night. up to more than 3000 meters. The high-power semiconductor laser application design technology of the laser camera, under the same device volume, the net output power of the laser is large, so that the nominal monitoring interval can be reached. The camera module secondary development optimization technology, under the same lighting conditions, the image clarity is high. The high-speed image focusing algorithm is designed to deal with the problem of slow automatic focusing or repeated focusing of images at night or in the absence of light. During the zooming process of the camera, the laser illumination area can intelligently and automatically fill the screen, without manual intervention, and the intensity and angle of the laser can also be manually adjusted remotely.
