The public security department is an important force in maintaining social order and protecting people's safety. When performing tasks, they often need to conduct investigations, searches and surveillance at night or in low light conditions. However, law enforcement at night often faces challenges such as insufficient light and complex environment. Traditional law enforcement equipment is difficult to clearly record the details of the scene and cannot meet the needs of the public security department. Therefore, with the advancement of technology, infrared thermal imagers have become the first choice for night vision equipment for public security departments. With functions such as infrared imaging, high-definition recording, and intelligent zoom, handheld multi-function night vision devices have become the "third eye" for law enforcement personnel to collect evidence at night.

Thermal imaging technology generates images based on infrared radiation emitted by objects. Infrared thermal imagers can generate images by detecting infrared radiation emitted by objects, so they are not limited by light. It can work under any lighting conditions and can detect objects that emit infrared rays, whether it is day or night. Let's take a look at how the "black technology" of this device can help improve law enforcement efficiency and safety!

It has built-in positioning module, electronic compass, laser ranging, red dot indication and image storage functions, and image fusion function. It can be used for day and night observation and target search. It is comfortable to use and easy to carry. It can be used for reconnaissance, surveillance, outdoor hunting and security protection.

1. Technical highlights: "hard core functions" of night vision devices

01. High-definition imaging, day and night

The new generation RE650 is a lightweight and miniaturized intelligent observation device that integrates five optical channels of infrared, low light, visible light, laser ranging, and red dot indication. It supports multiple working modes; even in complete darkness, smoke or rain and fog, it can generate clear images. For example, the multifunctional handheld night vision device supports 1080 HD video recording, visible light imaging during the day, infrared, low light and other modes at night, and supports thermal image fusion to ensure that no details are missed.

02. Multi-mode joint positioning and ranging

The built-in multi-mode joint positioning module GPS+BDS+SBAS+OZSS+GALILEO, with laser ranging function, can accurately identify targets 20m~5000m away, greatly expand the law enforcement scope, and accurately measure the target position. It has automatic identification and tracking functions, which can better discover and identify targets.

03. WiFi video transmission, optional external display device

It has recording, photo taking, and playback functions, and can be equipped with an external display device to achieve simultaneous viewing by multiple people

04. Safety protection and concealment

It uses red-free laser technology to avoid exposing the location of law enforcement personnel; it is equipped with a laser dazzling function to interfere with the suspect's actions in an emergency.

2. Application scenarios of public security departments: night investigation and search

Infrared thermal imagers play a key role in night investigation and search operations. It can determine the location of the target object by detecting the heat emitted by it, even if the target object is hidden in the dark or in a concealed object. This enables public security personnel to more efficiently find suspects and conduct arrest operations, increasing the success rate of the operation.

01. Crime scene investigation and evidence collection

In cases such as theft, infrared thermal imagers also play an important role in crime scene investigation. It can help the police collect evidence and confirm key details, and covertly record the dynamics of suspects, and fix evidence through one-click capture and video recording functions to avoid artificial fill light interference at the scene.

For example, after the blood is washed, the thermal imager can detect the thermal characteristics of the residual blood, thereby helping investigators find hidden traces. This is of great significance for criminal investigations. , night vision devices can.

02. Traffic law enforcement and rescue

When the traffic police handle accidents at night, they use thermal imaging functions to quickly locate the injured; the long-distance recording function can also clearly capture the license plate of the illegal vehicle.

03. Border and customs inspection and surveillance

In response to smuggling, illegal immigration and other behaviors, the public security department often needs to patrol and monitor border areas. Infrared thermal imagers can help police detect people lurking in border areas, whether it is day or night. It can detect potential threats by detecting emitted infrared rays, penetrate fog or jungle cover, and lock the target position with laser ranging, improve patrol efficiency, and ensure the safety of border areas.

III. Actual cases: How technology rewrites law enforcement efficiency

01. Case 1: Late-night pursuit

The police in a certain city used dual-spectrum night vision devices to lock the fugitive's traces in a completely dark suburb, and found him hiding in an abandoned vehicle through thermal imaging, and finally successfully captured him.

02. Case 2: Drug enforcement operation

In a night drug enforcement operation, law enforcement officers recorded the entire transaction process through the low-light mode of night vision devices, and high-definition video became the key evidence for court conviction.

Advantages and limitations of infrared thermal imagers

The application of infrared thermal imagers in public security departments has been widely recognized. It provides public security personnel with all-weather night vision, allowing them to see and track potential suspects in the dark. But ordinary infrared thermal imagers have many advantages, but they also have some limitations. It can work in any lighting conditions and can detect objects that emit infrared rays, providing public security departments with all-weather surveillance and reconnaissance capabilities. However, the images generated by a single infrared thermal imager may not be clear enough to provide detailed information, such as people's clothing and appearance. Therefore, Oonica RE650 processes the images of infrared thermal imaging and low-light night vision sensors through algorithms, fuses the images of the two at a certain ratio to highlight the target details, and highlights the thermal target. By observing the fused image, the user can see both the thermal target and the outline of the environmental background, improve the target recognition, and can quickly, accurately and clearly obtain the observed target. At the same time, combined with the recording and photo taking functions, the scene can be recorded and restored, which helps the public security department to achieve higher efficiency in law enforcement in multiple environments.

Advantages and Features

All-weather work: It does not rely on visible light, and can work normally regardless of day or night or bad weather, and is not affected by light conditions or climate conditions.

Strong concealment: passively receiving signals, not actively emitting detection signals, not easily discovered by anti-reconnaissance means.

Strong penetration ability: infrared thermal radiation can penetrate obstacles such as smoke, mist, rain, snow, etc., so that public security personnel can still clearly observe the target under complex meteorological conditions.

Long range: can detect targets such as people and vehicles at a long distance, such as telephoto thermal imagers can observe people over 3 kilometers and vehicles over 6 kilometers.

Can identify hidden targets: can penetrate camouflage and grass and leaves, the temperature and infrared radiation of human body and vehicle are much greater than grass and trees, not easy to disguise, and not easy to make wrong judgments.

Actual application scenarios

Concealed search and rapid identification: can quickly find targets such as terrorists hidden behind non-enclosed shelters such as trees or flowers, and can also determine whether the target is armed. Combined with high-definition cameras to further identify targets, timely adjust the execution plan, and record and save evidence.

Large-scale search and rapid identification: In open Gobi, desert areas, or in bad weather conditions, it can penetrate obstacles such as haze, quickly find heat sources, find hidden people, and see faces and identify criminals within a certain range.
