Night Vision Device

1.Night Vision Device Product Overview:

Night Vision Device is a kind of active infrared night vision technology, and its principle is to diffuse the laser point light source through the optics.Since the patrol and criminal investigation work of the public security department involves many links and complex contents, such as: area security patrol, online pursuit, checkpoint pursuit, key target monitoring, reconnaissance and evidence collection, temporary control and arrest, etc. Therefore, the application of intelligent face recognition mobile investigation and control technology in the public security department is of great significance; especially the long-distance all-weather evidence collection and intelligent face recognition comparison screening function, which is a reliable technical guarantee for public security law enforcement personnel to improve law enforcement strength and credibility; Fengtu Technology adheres to the research and development concept of "technology strengthening the police" for police equipment and equipment, and the newly developed and produced new portable laser night vision face recognition analysis system can effectively improve the law enforcement effectiveness of the public security and reduce the work intensity of law enforcement personnel.

Fengtu portable laser night vision face recognition and analysis system can be divided into front-end video acquisition system and wireless back-end framing analysis system according to the working mode. The system can not only meet the needs of temporary day and night imaging, 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 compare the photos of criminals or the face database of fugitives with the faces collected from time to time, assisting public security case handling and patrol personnel to promptly and accurately determine the identity of criminal suspects, and help case handling personnel improve public work efficiency and crackdown on criminals.

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

2. Features of Night Vision Device:

This equipment can help law enforcement officers to conduct long-distance reconnaissance and evidence collection 24 hours a day, all-weather, greatly saving the physical strength and reconnaissance endurance of law enforcement officers. It has been successfully applied to mobile long-distance patrols at night by public security, armed police, courts, enterprises and institutions. Because the system is operated by remote remote control of zoom, storage and adjustment, law enforcement officers can complete the reconnaissance and evidence collection tasks in front of the portable receiving and display box; the wireless image transmission function can make surveillance and reconnaissance more concealed and safe. The front-end recording system is placed on the roof or in a hidden place, and the reconnaissance personnel can conduct surveillance and reconnaissance in the 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 operation box, so it is safer and more reliable.

3. Night Vision Device Product Advantages:

1. Long-distance all-weather surveillance and control, 32x optical zoom, 64x digital zoom, 10-320mm aperture variable from F1.2-3.0, daytime monitoring distance up to 3 kilometers; nighttime monitoring distance up to 1.5 kilometers, wireless transmission, wireless control

2. The detection end uses a non-red exposure long-distance monitor with a high-precision electric pan/tilt, which is convenient for long-distance remote control operation

3. Intelligent face recognition function: import the suspect's photo into the machine's face database, and when the suspect appears, it can be identified and compared for similarity, and at the same time capture the video and alarm

4. Intelligent retrieval function: event detection, face image detection, name detection, attribute detection can be selected according to needs, and all images, videos and other information of the people who need to be detected can be quickly retrieved

5. Perimeter protection function: cross-border detection and regional intrusion detection can be activated as needed

6. Alarm function: Motion detection alarm, occlusion alarm, face recognition comparison alarm, stranger alarm, event alarm, etc. can be set as required

7. 100,000 facial information can be stored in the device at the same time

8. Face similarity comparison: face similarity can be set according to needs. When the face similarity in the monitoring range reaches the set value, an alarm will be triggered.
