Application of infrared thermal imager in safety precautions
Infrared thermal imagers have been widely used in security systems because of their special features, and have become stars in security monitoring systems.
The infrared thermal imager has a concealed detection function. It does not require visible light, which can make criminals unaware of their working location and existence, thus producing wrong judgments and leading to the uncovering of criminal behavior.
In some very important units, such as: important administrative centers, bank vaults, confidential rooms, military sites, prisons, etc., it is especially used for this kind of infrared thermal imager, it can be in operation for 24 hours, and at any time Analyze the background information, and if there is a change, you can send out an alarm in time, and you can automatically handle the relevant situation through the processing of smart devices, and report the situation at any time to obtain further processing opinions.
For these special important departments, the sensitivity of their prevention is much higher than that of other prevention systems. For example, if they leave work in these units, as long as someone is hiding inside, the system will generate an alarm signal.
As everyone knows, border defense is a very difficult thing. China ’s borders are very long, and the ocean is vast. Due to the harsh outdoor environment, many systems are unlikely to serve as a preventive role, especially on rainy, snowy, foggy, and windy days, border patrol is also a very difficult task . If personnel patrol is used and observations are made with telescopes, the observation effect is often poor due to the short wavelength of visible light, resulting in the phenomenon of missed, mischecked and mischecked.
Infrared thermal imager can detect infrared rays with short wavelength, so it can be observed from a long distance, especially suitable for wind and rain weather. According to Hong Kong's "Dongfang Daily" report: The Hong Kong police placed five infrared thermal imaging cameras in a border area. During the trial process, it successfully cracked many cases of illegal immigrants, and the efficiency was much higher than the original manual inspection. Therefore, the Hong Kong police plan to purchase a new system this year to strengthen the prevention of illegal immigration cases.
On the coast, infrared thermal imaging cameras can quickly track ships going to and from. Smuggling by the sea is now often carried out by "big flying". These "big flying" have no lights, high horsepower, and strong maneuverability. They are often easy to get rid of our private officers and border guards. Distance tracking these "big flying", even in the radar ground corners, this system can also operate normally, especially in the dark night and bad weather, can give full play to its good features.
In the same way, infrared thermal imaging cameras can be applied to the perimeter defense of living communities, and the perimeter defense of important areas can achieve the effects that are not easily achieved by general surveillance systems. , It is easy to produce dead corners during installation, which is not conducive to comprehensive control of the monitoring surface. Another point is that it is easily disturbed, such as the invasion of small animals. Installing an infrared thermal imager can overcome the above two shortcomings and reduce false alarms.
In China, with the expansion of urban traffic and the extension of various highways and railways, the normal operation of these systems has also become a great problem, especially during night safety inspections. The aircraft can successfully complete these tasks. It can find blocked vehicles, malfunctioning cars, and targets that need to be locked. In foreign countries, many units have actually used these systems to conduct inspections.
The acrylic LED illuminated sign is an increasingly popular tool for promoting goods and services in point-of-purchase environments. When shopping online, there is a huge selection of signage equipment to browse, which can often be confusing for advertisers. So why is the LED lighted sign increasing in popularity? The reasons are numerous. First, LED Illuminated Signage are unique, especially the units for sale in these categories. Secondly, illuminated custom sign board provide increased exposure for advertisements.
