In recent years, explosion-proof cameras have become irreplaceable security equipment in special industrial production environment.  With the rapid development of security technology, explosion-proof cameras begin to develop towards high definition and intelligence. High definition and low illumination will be the main development trend of explosion-proof cameras in the next few years.  Today, I would like to introduce to you the working principle and installation precautions of explosion-proof cameras. In short, pay attention to the details!  Watch your posture!  The working principle of explosion-proof camera is to inhibit the generation and occurrence of four elements of explosion so that electrical products can still work normally in high-risk environment. The four elements of explosion are: combustible gas, dust and mixture on site and form a certain concentration;  There is sufficient oxygen on site to react with combustible materials.  Sufficient temperature on site can cause the mixture to burn in oxygen;  The narrow space on site is enough to make the heat after combustion gather a certain concentration in a short time and even explode.  Any of the above four explosive elements can effectively prevent explosion.  What problems should be paid attention to when installing explosion-proof cameras?  1. Pay attention to installation details.  Avoid some locations with complex light receiving positions for installation, otherwise a fixed focus explosion-proof camera will always face the strong light of some vehicles.  2. Pay attention to the posture selection of explosion-proof camera, especially the light adaptability of explosion-proof camera.  Overlooking angle is the most commonly used working posture of explosion-proof cameras. Its disadvantage lies in the sacrifice of details.  Look-up installation is also a reference scheme. The disadvantage is that this method has high requirements for the light adaptability of explosion-proof cameras.  In theory, explosion-proof cameras will be used more and more widely, but in fact, the usage of explosion-proof cameras is not very large.  This phenomenon is mainly attributed to the relatively high cost of explosion-proof cameras and the insufficient awareness of the necessity of "explosion-proof" among engineers and users.  At present, the explosion-proof camera market is mixed with good and evil people, and price war is serious.  Only when major manufacturers surmount obstacles and establish a safe and orderly domestic explosion-proof monitoring market order can they usher in a broader development space.
