Night Vision Device

1. Night Vision Device product overview:

Night Vision Device shoots an infrared beam outward, illuminates the target, and converts the infrared image reflected by the target into a visible image.Since the inspection and criminal investigation work of the public security department has many links and complex content, such as: area security inspections, online pursuits, escape pursuits at checkpoints, monitoring of key objects, reconnaissance and evidence collection, temporary control and arrests, etc. Therefore, the application of intelligent facial recognition mobile investigation and control technology in the public security department is of extremely important significance; especially the long-distance all-weather evidence collection and intelligent facial recognition comparison screening functions are reliable technical guarantees for public security law enforcement personnel to improve law enforcement efforts and credibility. Fengtu Technology adheres to the research and development concept of "powering police with technology" as the research and development concept of police equipment. The newly developed and produced new portable laser night vision facial recognition analysis system can effectively improve the law enforcement effectiveness of public security and reduce the work intensity of law enforcement investigators.

Fengtu portable laser night vision face recognition and analysis system can be divided into: front-end video collection system and wireless back-end framing analysis system according to the working mode. This system can not only meet the needs of day and night imaging for temporary control, but also realize the local high-precision face recognition comparison screening function. The device makes full use of computer vision technology, face detection technology, and face recognition technology to detect illegal crimes. Compare photos of persons or face databases of persons pursuing fugitives with faces collected from time to time, assisting public security case handling and inspection personnel to promptly and accurately determine the identity of criminal suspects, helping case handling personnel improve public work efficiency and crack down on illegal criminals. intensity.

The complete set of equipment of this system is powered by imported lithium batteries, which is easy to carry and not affected by the regional environment. It is more suitable for the professional requirements of mobile non-fixed-point covert surveillance and video evidence collection. The farthest monitoring distance is more than 1,500 meters at night and more than 3,000 meters during the day.

2. Night Vision Device features:

This equipment can help law enforcement officers conduct long-distance reconnaissance and evidence collection 24 hours a day, all day long, greatly saving law enforcement officers' physical strength and reconnaissance endurance. It has been successfully used in night-time mobile long-distance inspections of public security, armed police, courts, and enterprises and institutions. Because all operations of the system are long-distance remote control of zoom, zoom, storage and adjustment, law enforcement officers can complete reconnaissance and evidence collection tasks in front of the portable receiving display box; the wireless image transmission function can make surveillance and reconnaissance more concealed and safer, allowing front-end recording The system is placed on the roof of a building or in a hidden place, and reconnaissance personnel can conduct surveillance and reconnaissance in a car or in a hidden corner. Even if the front-end surveillance is discovered, attacked, or destroyed, the evidence has been stored in the portable receiving and display operating box, so it is safer and more reliable.

3. Night Vision Device product advantages:
