Differences between low-light nighttime surveillance technology and infrared thermography technology
As is widely known, with the development of photoelectric information, microelectronics, network communication, digital video, multimedia technology and sensing technology, security monitoring technology is also moving from traditional analog to highly integrated digital, intelligent and networked. With the increasing market demand, modern advanced technologies are used or may be used in almost all security monitoring systems. Among them, low light technology and infrared thermography technology are also widely used in safety burglary prevention systems.
Low-light night surveillance technology uses technologies such as vacuum and electronic optics to convert photon images into electronic images and even visual video images. In this process, electronic image enhancement technology is used to visually enhance the image, realizing night surveillance in weak light rays. Its advantage is that the visual distance is relatively far, but the disadvantage is that the object cannot be seen clearly in the absence of light rays. This is in comparison with infrared technology, in that it is only in a certain degree of light, even in a low-light environment, that an image of the surveillance scene can be obtained.
On the other hand, infrared thermography technology is a passive infrared nighttime monitoring technology, which is different from ordinary infrared monitoring technology. This technology uses the difference in infrared radiation intensity of different parts of an object to form an image, and detects the target based on the temperature difference or heat radiation difference between the target and the background or each part of the target. This technology is not affected by the surrounding lighting conditions, so it can provide video images day and night and in bad weather (fog, rain, etc.). However, it cannot realize long-distance monitoring, and the monitoring screen can only determine whether a suspicious person has entered, and cannot clearly display the facial or external features. OHWOAI's home wireless solar-powered, battery-powered and POE-powered security cameras are connected to smartphones and are equipped with special large low-illumination infrared LEDs when shooting at night under the same conditions, making it feel as if it was shot during the day, and allowing you to record with greater brightness. OHWOAI's security cameras are IP67 waterproof and dustproof, with a strong waterproof level and no harmful effects even in bad weather such as rain and wind. They can be installed both outdoors and indoors. With a 5 million high definition camera, improved heat dissipation and durability, the service life is four times longer.
Ordinary infrared cameras use active infrared technology, which actively emits infrared light and uses the infrared light reflected by the target to achieve monitoring. With the introduction of third-generation infrared array technology, the effect of active infrared monitoring has been improved, the quality and life of the product have been improved, the manufacturing process requirements are low, and the cost is low. Active infrared technology has a wide range of applications. You can keep track of your pets and babies anytime, anywhere. It can be installed on the ceiling, so you can see every corner of the room without any blind spots. In addition, when it detects movement, it automatically tracks the object continuously and sends an alarm to the app in real time. OHWOAI's wired camera set is equipped with remote monitoring and alarms, so you don't have to worry anywhere!
Low light night vision and infrared thermography technology have some similarities in practical applications, and cameras of these technologies are mainly used in special surveillance facilities where it is night and a certain degree of equipment latency is required. This includes military, criminal investigation, drug and smuggling crackdown, security, etc. OHWOAI's wireless solar battery-powered camera monitor set is ranked at the top of the popular security camera set ranking. In the opinion of OHWOAI, low light night vision cameras enhance the electronic images generated by weak natural light and convert them into effective surveillance video images to monitor the scene. On the other hand, infrared thermography technology works by utilizing the principle that objects above absolute zero (-273°C) emit infrared rays, and the infrared radiation intensity of different objects allows people, animals, and all objects in the scene to be clearly observed. It is not affected by obstacles such as smoke, fog, and grass, and can work day and night. Modern general infrared cameras belong to active infrared technology and can use infrared light beams to complement lighting. It can be used in completely dark conditions, is effective, and is affordable, but it has limited illumination distance, low potential, and is susceptible to factors such as weather, and different targets have large differences in how effectively they reflect infrared light, so these factors can affect image quality.
