Long-distance laser night vision camera night monitoring video effect

With the rapid development of China's high-speed railway, rail transit safety has become the focus of attention. Trains travel frequently at night. Due to the low visibility and poor visibility at night, this puts forward higher requirements for the clarity of monitoring images along railway tracks and transportation hubs. At present, railway security has begun to install real-time surveillance cameras in batches, but most of them can only take pictures during the day, and it is difficult to achieve the purpose of nighttime security. In order to more effectively prevent the occurrence of public security, unexpected accidents and fearful events during the operation of trains, it is necessary to adopt advanced night vision technology and establish a safety monitoring system for rail trains. At present, the effective viewing range of conventional night surveillance cameras is less than 100 meters. To achieve seamless coverage along the railway line, the number of the entire system is very large, the wiring is very complicated, the amount of engineering is huge, and the later maintenance also increases the difficulty. Railways usually require 300 meters to 1000 meters. As long as appropriate night monitoring technology is used, the effect of night monitoring video can be ensured, and the construction volume and long-term investment can be reduced at the same time. Product introduction: The composite speckle suppression (UDF technology) is adopted to eliminate laser speckle, and the fill light effect is average; laser synchronous zoom (STZ technology), the zoom synchronization is faster; Structural design, can be used in high and low temperature, dusty and harsh environments Application range: City high-altitude view, airport perimeter, maritime and fishery administration, forest fire prevention, port and wharf, environmental maintenance, border defense, etc. Functional features: 1. The whole machine has reached the IP66 protection level, which can be used in the harsh environment of upper and lower temperature and dusty environment 2. Fog penetration function: spectral response range: 400-1000nm; support optical fog penetration, fog penetration algorithm enhances fog penetration effect, and can penetrate mist/haze to present clear black and white images 3. Using shock composite speckle suppression (UDF technology) to eliminate laser speckle, the effect of supplementary light is average 4. Laser synchronous zoom (STZ technology), zoom synchronization is faster 5. The laser photoelectric conversion rate is as high as 60% or more, which saves energy by more than 30% compared with the conversion rate of similar laser products 6. Software remote control laser xy-axis fine-tuning (SLHC technology), no need to adjust the window, ensure tightness, and eliminate the need for manual adjustment by personnel now.
