How to use the underground explosion-proof camera?

Talking about the use principle of underground explosion-proof camera

The tracking function of underground explosion-proof camera is actually an image analysis function, which depends on the rapid rotation speed and accurate positioning of pan/tilt. If the pan/tilt of explosion-proof camera is slow and inaccurate, it is impossible to automatically track an object. This function is usually realized by setting software accessories and background operation control.

Underground explosion-proof cameras have the advantages of high cost performance and simple technical structure, resulting in a large influx of surveillance camera manufacturers, which leads to the homogenization of "virtual" products and the situation of "both supply and demand in the security market". Therefore, some manufacturers who have mastered the core technology of underground explosion-proof cameras start with DSP function control scheme, refine internal functions, improve image quality, adjust color reproduction and reduce night vision noise. , extend the night vision distance and improve the product performance in the underground explosion-proof camera technology; But more manufacturers start with the external hardware of the camera, change the external structure, increase the color of the shell, use dazzling infrared lamp, and enhance the brightness of the surface paint. It gives people a feeling of novel appearance, dazzling and bright eyes. No matter what the standard is, it should be based on meeting the requirements of users. The matching between different grades of cameras and camera lenses may have several times or even dozens of times different sensitivity to the light emitted by the same group of infrared lamps, and the performance is very different. What is the visible distance, what is the discovery distance and what is the illumination distance? These specious statements are all confusing the user's rhetoric.

Self-inspection of explosion-proof camera is very important. For example, if the tripod head is stuck or the self-inspection is not in place, it will be difficult for the product to play a practical role. Represents vertical definition and horizontal definition respectively, and the corresponding groups have given the number of lines. When testing, you can focus on the distant scene, or you can focus while measuring. It's best to use both. You can see the difference between this camera. If the explosion-proof camera is used in oil fields and mines with extreme environment, it may be MINUS 30 in winter. C the pan/tilt shaft may freeze, and the explosion-proof camera may stop working without self-inspection.

Infrared ray is the main imaging light source of underground explosion-proof camera at night, but it is a kind of stray light during the day, which will reduce the clarity and color reproduction of explosion-proof camera in coal mine. The built-in filter of the camera can prevent and distinguish infrared rays from participating in imaging. When the appearance of products is similar, the requirements of users and engineers for the color and chromaticity of cameras with the same "resolution" will naturally become the first choice to distinguish the performance of underground explosion-proof cameras.

In order to enhance the environmental adaptability of explosion-proof cameras, it is usually necessary to add value-added accessories such as sunshade, heater, filter, wiper, fan/semiconductor refrigeration device, etc. to ensure the stable operation of the equipment and the clear monitoring picture. Shandong Jinan China Coal Electrical Appliance Co., Ltd., specializing in the production of explosion-proof monitoring equipment, the quality has been recognized by third-party certification bodies, factory outlets, reliable quality, the highest cost performance in China, welcome to buy.
