Classification of laser cameras

The number of laser camera lines is 420 and 650.

The scheme of line 420 is Sony 3 142+633, which is a classic scheme of Sony, with good night vision effect and stable quality.

EFFIO-E is the scheme used in line 650, and it is the clearest scheme of Sony, with outstanding colors, high definition and outstanding night vision. It is also the most widely used scheme of 20 1 1 and the future trend of this scheme. Close-range laser camera (30-80m)

Due to the advantages of high brightness, strong light emission and long service life, close-range laser cameras have played many roles in forest fire prevention and ocean navigation. However, due to the disadvantage of laser lamp: laser infrared has homogenization effect, but the effect is poor at close range, so the laser camera at close range (30- 100 meters) has not been developed until now. Shenzhen, China is the capital of cameras, and many camera manufacturers are involved, such as Qiao 'an Technology.

Close-range laser camera (50-150m)

There are still few manufacturers who can make 50-150m laser cameras in the industry. The specific reason is that some manufacturers have not fully mastered the core technology of laser. Laser camera technology is different from thermal infrared imaging technology and infrared night vision technology. Thermal infrared imaging technology can only see the thermal profile of people and objects, but can't see the real face of objects. Although infrared night vision can also see the target, it can't overcome the infrared storm, can't hide the observation, and is easy to expose the target itself, and the image is disturbed by light waves. Laser camera is a kind of night vision camera product, which can directly observe people and things from the monitor at night without visible light, just like during the day. Compared with common infrared cameras, laser cameras have long life, high definition and long shooting distance. Low carbon and no heat dissipation.

Compared with the traditional video camera:

The first point is that the clarity is greatly improved. Although infrared cameras can see images at night, they often cannot see people's faces clearly. In addition, the monitoring distance of ordinary infrared cameras is limited, which is very regrettable in some places with strict security monitoring. Laser cameras can ignore the intensity of light. Through the laser infrared module and ultra-low illumination lamp module, the camera can realize high-definition night vision at close range in a completely dark environment, while ensuring clear imaging.

The second point is that the service life is longer, and the service life of laser surveillance camera is three times that of ordinary infrared camera. This is particularly prominent in an environment that requires 24-hour monitoring.

The third point is its low-carbon life function. The traditional infrared camera radiates a lot of heat, which not only consumes a lot of electricity, but also can't dissipate heat inside the camera body, which leads to the overheating of the camera body and seriously affects the life of the electronic components inside the camera, while the laser camera does not have this hidden danger.

Long-distance laser camera (0.5-2km)

The pan/tilt camera integrated with laser night vision adopts the world-leading optical, mechanical and electrical integration technology. In the dark night sky, the target activities within the range of 200-300 meters can be clearly monitored on the whole screen, and the field of vision during the day can reach 1-2 kilometers. Unique high-power semiconductor laser application design technology, under the same installation volume, the net output power of the laser is large, which can really reach the nominal monitoring distance. The camera module secondary development optimization technology has high image definition under the same lighting conditions. The design of image high-speed focusing algorithm completely solves the problem of slow automatic focusing speed or repeated focusing at night or in the case of insufficient light. In the process of camera zooming, the laser irradiation area can fill the screen intelligently and automatically, and the laser irradiation intensity and angle can be adjusted manually and remotely without manual intervention.

The laser safety of equipment is fully considered. The laser is kept off during power-on self-test, and the maximum divergence angle is automatically reached when the laser is started. The power density of laser can be controlled automatically. Under the premise of ensuring lighting, the excessive power density is strictly limited, which conforms to the national safety laser power density standard. In addition, automatic shutdown function can be added according to user's customization. During the maintenance inspection, people and things at close range can be automatically detected, and the laser can be turned off immediately to further ensure the safety of maintenance personnel.

Integrated high-speed pan/tilt design can realize all-round high-speed monitoring of horizontal 360 and vertical180. 128 intelligent functions such as precise preset position, four cruise groups, pattern scanning, left and right scanning and timed execution can realize monitoring automation. The position information (latitude and longitude) function of Yuntai can display the current position of the equipment on the screen. The pan/tilt can automatically adjust the rotation speed according to the change of the focal length ratio of the camera, so as to ensure that the image is clear and stable in the process of fast moving. Four alarm inputs and one alarm output function are standard, which can be connected with alarm equipment to realize alarm linkage function. The integrated wiper can clean the lens remotely. The two-dimensional optical axis adjustment mechanism is convenient for users to correct the optical axis deviation by themselves and ensure the effective irradiation of laser within the visual angle range of the lens.

Anti-hurricane design, high-torque high-speed stepping motor power system, fast positioning speed, bond alloy structure, anti-oxidation and salt spray coating on the surface, IP66 protection level, which can be applied to various natural environmental conditions.

Four advantages of laser camera over infrared camera.

1. HD. Although infrared cameras can see images at night, they are often not clear. In addition, the monitoring distance of ordinary infrared cameras is limited, which is not feasible in some places with strict security monitoring. Laser camera is different, it can ignore the intensity of light, and through laser infrared module and ultra-low illumination module, it can realize hundreds of meters of night vision even in completely dark environment, and the imaging is relatively clear.

2. Long life. The life of laser surveillance camera is three times that of ordinary infrared camera. This has outstanding advantages in an environment that requires 24-hour monitoring.

3. The focal length of the lens can be adjusted automatically. 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, thus providing clear image quality.

4. Low-carbon life function. The traditional infrared camera dissipates a lot of heat, consumes a lot of electricity, and the internal heat cannot be dissipated, while the laser camera does not have this problem.

The advantages of laser cameras are really obvious, and the disadvantages of infrared cameras are also outstanding. But it doesn't mean that the laser machine has no shortcomings and the infrared machine has no advantages. It is impossible to say that the laser will completely replace the infrared machine for a long time. First of all, because of the use of laser light source and zoom lens, the expensive price of laser surveillance camera is one of the most important factors that hinder its popularization. Secondly, because of the long monitoring distance and relatively small viewing angle, more laser cameras are needed for large-scale monitoring, so laser cameras are mainly used with ordinary infrared cameras to make up for the shortage of long-distance monitoring. The third point is about the close-range laser camera. Because the brightness of the laser lamp itself is too strong, the short-range irradiation effect will be poor. This is a common problem in the industry. Although some close-range products have been listed gradually, the effect is not ideal, mainly because the core technology is not in place. This also hindered its market popularization to a great extent.

Compared with the high price of laser machine, infrared machine also has its advantages, such as relatively affordable price, continuous progress in technology, and infrared machine in line with China's national conditions. Even in economically developed countries, laser cameras cannot be popularized, so there is still a long way to go to popularize laser cameras in China.
