Long focus camera security monitoring

Most of the current security monitoring manufacturers for conventional scenes (daytime) monitoring technology tends to mature, the gap is small, but the night vision is a mixed bag. Most of the security monitoring manufacturers for conventional scenes (daytime) monitoring technology tends to mature, the gap is small, but the night vision effect is a mixed bag. Low illumination, poor lighting conditions in the region is the high incidence of criminal behavior. Good low illumination effect on the completion of 24-hour monitoring, custody of evidence, to combat crime will have a great help, which is also the key link in the future bidding effect of the camera PK.

Starlight level night vision technology is widely demanded

According to the standardized definition, the current security industry will be divided into four levels of front-end camera: ordinary level camera, ordinary illumination are greater than 0.1Lux; illumination range between 0.1 Lux to 0.01 Lux camera, commonly known as low illumination camera; and is known as the moonlight level of the camera, the illumination range of 0.01Lux to 0.001Lux; when the illumination range reaches And beyond the 0.0001Lux time, will arrive at the "starlight level" of ultra-low-light cameras.

Starlight level camera, literally means that in the starlight environment, even without any external auxiliary light source, can also show clear color images, which uses a super-sensitive image sensor and the unique electronic multiplier and noise control technology can greatly improve the sensitivity of the camera, and has a 24-hour full-color real-time effect, no ordinary low-light cameras show the phenomenon of trailing to meet the high-quality night-time monitoring needs, and low power consumption. Surveillance needs, and low power consumption, image effect is true, no color deviation. In the starlight level network HD camera 7 × 24 hours of the experimental site, in the dark room with the starlight level camera images are not only clear, and color realistic.

In the "Safe City" project, financial, cultural and museums, hotels, office buildings, residential communities, safe villages, campuses, ports, highways, streets and other places, the performance of the camera is relatively high, due to the conventional type of camera is difficult to meet the demand for 24-hour continuous monitoring, so the low-light camera has become the primary choice. These applications, such as "Safe City" project, the lack of light at night, but also the impossibility of installing a wide range of complementary lighting equipment, in this case, to get a better monitoring effect, it is necessary to install high-quality low-light cameras, not only to ensure that the monitoring effect, but also simplify the system to form and complete a better reliability and lower cost. Cost.

In addition to these traditional monitoring categories, in the forest, hospitals and other common will also install low-light cameras, these places are not ideal for ambient lighting, and should not be added to the light source. For example, hospitals, in order to ensure that the patient rest, not convenient to make up light and other ways to improve the environmental illumination, it can only be in the performance of the camera to find a way, so the need to install low-light camera. There are some places do not have the conditions to add a light source, but also need to use low-light cameras. For example, some construction sites, oil fields, factories, yards and other outdoor places, monitoring a large area, and often no street lights, in this case, the use of ordinary cameras can not guarantee that the monitoring effect, but also the need to use high-performance low-light cameras, in order to ensure that the effective monitoring effect.

Surveillance manufacturers to compete

Ultra-low-light camera development is generally recognized by the market. Products, whether from the function, effect, stability, or from the ease of use, human nature care index to the environmental protection index, etc., are substantially ahead of traditional camera products.

In this case, Hikvision and other security companies have launched a starlight level effect of ultra-low-light cameras. Hikvision launched a full range of starlight level HD front-end product line "starlight family - DARKFIGHTER", "starlight family" series of front-end products with 2 megapixel (1920 × 1080) high definition resolution, the use of advanced Starlight-level ultra-low illumination CMOS image sensor, excellent nighttime light sensitivity, with the depth of the optimized 3D noise reduction algorithms, completed the color low illumination arrived at 0.001Lux of the real starlight-level ultra-low illumination, the real "Starlight family" thus born. At the same time the series of starlight level products are also equipped with ICR infrared filter automatic switching and 120dB of ultra-wide dynamic, in the backlight environment can also have a high-quality images.

With the enhancement of camera pixels, single-pixel sensor (sensor) sensing area is getting smaller and smaller, low illumination, especially color low illumination will be more and more difficult to complete. IPC set of mechanical, optical, image, network, harsh environment applications in one, in order to overcome this technical challenge, YUVAD initiated the IPC components of the special technical research, touching on a total of 69 items, 206 small items, constructed a In the electromechanical design, ISP image, engineering applications, consumer testing and other areas of advanced technology foundation. And took the lead in launching the 1080P level of starlight level IPC, with many years of high-definition ISP comparison of the accumulation of 1080P clarity of the advantages of the sudden move, focusing on debugging in a variety of environmental illumination in the picture of the effective clarity, especially low-lighting environment of the clarity of the product in a similar program is still far ahead of the rest.

Professionals believe that, with the development of starlight level ultra-low-light camera gradually mature, will absorb more and more manufacturers compete, after the major monitoring manufacturers to optimize its technology and performance enhancement, starlight level ultra-low-light camera will also enter the substantive use and implementation stage.
