In the security monitoring system, with the gradual improvement of equipment and people’s increased awareness of prevention, the use of infrared cameras has become increasingly high and has gradually developed into a trend not only in important sectors such as banks, museums, and archives. Applications have also become more and more popular in general monitoring environments such as residential quarters.
The imaging principle of infrared cameras At present, the working principle of infrared cameras can be roughly divided into two types, one is passive infrared technology, and the other is active infrared technology. Passive infrared technology is based on the physical characteristics of infrared light emitted from any object above absolute zero, and the object is determined by the red light emitted by the object. Active infrared technology relies on infrared devices to emit red light and monitor the red light reflected from the object.
Using infrared night vision technology, imaging is clear Because most current civilian infrared cameras use active infrared technology, they can still maintain clear imaging in relatively complex night vision environments. Compared with other ordinary low-light surveillance cameras, the advantages are quite obvious.
The advantages and disadvantages of infrared cameras are highly concealed. Since infrared cameras do not emit any visible light during the work process, they have a very high level of security in their concealment. On the other hand, the use of densely populated areas such as residential areas also avoids the problem of light pollution.
The price is relatively low Because the infrared camera works at work, it usually uses the light board at night to supplement the light source of the camera, so it is cheaper than other cameras with night vision function.
Insufficient red camera of infrared camera When the camera releases infrared light, some visible light will be mixed in. When this kind of visible light and infrared light meet together, it will have a certain impact on the imaging quality of the camera. This is the phenomenon of red storm. However, if the infrared light with a larger wavelength is selected, the red storm phenomenon can be greatly reduced.
This is a common problem with infrared cameras, although different brands may have some differences in their useful life. However, the overall life span is shorter than other types of cameras. Of course, proper accessories and timely maintenance are also effective means to extend the life of the camera.
Camera color cast problem This phenomenon is common during the day. Since the infrared camera generates the image mainly by sensing light, the day light component is more complicated. Therefore, there will be some infrared interference, tutor color imbalance, appear to be biased.
The future of surveillance cameras is used as front-end equipment for surveillance. The development direction of infrared cameras is also similar to that of other types of cameras, focusing on networking, high-definition, and intelligentization. In addition, if you can better integrate with laser night vision technology, it will undoubtedly greatly improve the overall camera quality of infrared cameras, more and better meet the needs of users. It is believed that in the near future, under the trend of increasing integration of many smart technologies today, the working capability of infrared cameras will surely be substantially improved, bringing a new model to our security work.
