Does the camera emit infrared rays?
Some of the cameras would emit infrared rays. For example, the Xiaomi Smart Cat Eye 2 was equipped with eight 940mn infrared night vision lights to fill in the light when there was insufficient light. In this case, the camera would emit infrared light when taking pictures. Some infrared cameras used for surveillance were equipped with infrared LED fill light, which automatically turned on to emit infrared light at night or when there was insufficient light to enhance the camera's monitoring ability in extremely low light environments and ensure the continuity and stability of the monitoring image. However, not all cameras would emit infrared rays. There were also ordinary cameras that relied on other technologies or took photos under sufficient lighting conditions.

The camera on the phone can see infrared rays
In theory, a cell phone camera could sense infrared rays. The principle of cameras and cell phones was that the light passed through the lens and gathered the image on the LCD. After processing, it was displayed on the display screen. The LCD could sense all the light, but to avoid interference, a layer of filter was usually added to filter out the light other than infrared and infrared light, so that the cell phone appeared to be between red and infrared. However, some phone cameras could sense infrared rays when the filter was removed or the filter did not completely filter the infrared rays. For example, when detecting the quality of the infrared remote control, you can turn on the camera function of the mobile phone, aim the lens at the remote control's emitting LED (where there is a small light at the top of the remote control), press any key on the remote control, and if you see the emitting LED emitting red light, it means that the remote control is working normally. This also proves that the mobile phone camera can see the infrared rays emitted by the infrared remote control. However, due to the difference between the camera and the remote control, it was not always possible to successfully see the infrared rays. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
infrared camera color
Under low illumination (<0.01Lux), the infrared camera would display a black and white image. The infrared thermal imaging surveillance camera's image would be based on the temperature distribution. The higher the temperature, the brighter the color. Conversely, the lower the temperature, the darker the color. In night vision systems that used infrared light to illuminate the night, the scene was usually only rendered in green and could not display the colors visible under normal light. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Phone, camera, infrared
The principle of the phone camera and infrared light was as follows: Light contained a variety of wave-length ranges, among which the infrared wave-length was greater than 760mn, invisible to the human eye. The principle of digital cameras and cell phones was that light was gathered on the charge coupled device (CCD-a charge coupled device) through the lens and then processed to display an image on the display. In theory, the cell phone could sense all light, but to avoid interference, it usually filtered out light other than infrared and infrared light. However, when there was infrared light, the phone camera could see the phenomenon related to infrared light. For example, when detecting whether there is an infrared camera in the room, you can use this feature of the mobile phone camera to use the mobile phone camera in complete darkness. If a small red dot appears in the picture, it is usually the light emitted by the infrared camera, which means that there may be a camera in the room. Also, when testing the infrared remote control, you can turn on the camera function of the mobile phone, aim the lens at the remote control's emitting LED (where there is a small light at the top of the remote control), press any key of the remote control, and if you see the emitting LED emitting red light, it means that the remote control is working normally; if there is no response or red light, the remote control may have a problem. In addition, the infrared camera phone was a smartphone equipped with an infrared camera function. Its working principle was to emit infrared rays, illuminate the object being photographed, and then receive the reflected infrared rays to form an image. This kind of phone had unique advantages at night or in low-light environments, such as night vision, which could be used for indoor shooting, smart home monitoring, privacy protection, etc. However, there were also limitations such as image quality may not be as good as traditional camera phones, light interference in bright light environments, and high production costs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

infrared camera image format
The data format of the infrared image was the same as that of the gray-scale image. It was a single-channel image. The color image was a three-channel image composed of R, G, and B components for each of the four elements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
infrared camera chemical fiber
There was a certain connection between infrared cameras and chemical fibers. On the one hand, in industrial scenes such as Yizheng chemical fiber related equipment monitoring, infrared thermal imaging technology (infrared camera related technology) was used to measure the surface temperature of the spherical tank in order to better monitor the condition of the equipment. On the other hand, in the discussion of the One Plus 8Pro's see-through function, it was mentioned that infrared rays were limited by the wavelength and could only penetrate chemical fiber materials (such as pet). This see-through ability was limited and had to meet certain conditions. For most of the clothes worn daily (even if it was made of chemical fiber, if it was not extremely thin), there was no need to worry about being seen through. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
420-line 50-meter infrared camera
The infrared camera was a kind of camera equipment that integrated a camera, a protective cover, an infrared lamp, a power supply and cooling unit, and so on. 420 lines indicated the camera's definition level. The higher the number of lines, the clearer the image. 420 lines belonged to the relatively lower definition specifications. 50 meters means that the effective detection range of the infrared camera is 50 meters. The working principle of this camera was to use the spectral characteristics of the infrared light that could be sensed by ordinary black-and-white CCD-based cameras, and to use infrared lights as an " illumination source " to achieve night vision imaging. The infrared camera technology was more commonly used in the field of security monitoring. Its development trend was digital, intelligent, network, and integrated, which could easily link other security equipment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is it safe to idle the infrared camera?
You only asked " Is it safe to leave the infrared camera idle?" There wasn't much to polish. If he had to answer directly, there was a certain safety risk in idling the infrared camera. If it was obtained and reactivated by someone with ulterior motives, it might invade the privacy of others, or if the battery and other components aged, there might be a danger of a short circuit causing a fire. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Led infrared camera series
The LED infrared camera was a camera that integrated a camera, a protective cover, an infrared lamp, a power supply and cooling unit, and so on. Its working principle was to use an ordinary black-and-white camera to sense the spectral characteristics of infrared light (it could sense visible light and infrared light), and cooperate with infrared lights as an "illumination source" to perform night vision imaging. There were many types of cameras. For example, in the field of shooting wild animals, there were black light infrared cameras, which used black LED lights. There was no visible light when shooting, which was suitable for night surveillance and would not scare away animals. There were also semi-white cameras, which emitted weak visible light when used at night, which might affect the behavior of some animals. There were also visible light cameras, which were generally used during the day when there was sufficient light. The filter technology in the infrared camera included an infrared cut-off filter, which allowed visible light to pass through during the day and cut off infrared light to ensure normal color image capture. At night or when there was insufficient light, it was switched or removed to allow infrared light to enter and cooperate with night vision monitoring. The full-spectrum filter allowed the camera to receive both visible and infrared light at the same time. However, during the day, the image may have color cast or unnatural colors. It was rarely used in traditional infrared monitoring systems, but it may be used in special applications (such as environments that need to monitor both visible and infrared light). The development trend of infrared cameras is digital, intelligent, network, and integrated. It can be more convenient to link other security equipment (such as temperature, humidity, smoke, intrusion, etc.), as well as action equipment such as alarms and locks to form a powerful security system. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
