Huaqiang Security Network News ] With the rapid development of the surveillance industry, the application of cameras is also very extensive. Although the explosion-proof cameras and riot cameras are only one word difference, the functions of the cameras do vary greatly. Let me introduce you to the following.
Judging from the literal pronunciation, the anti-"violent" camera and the anti-"explosive" camera are easily disturbed, and people are habitually putting the two together for comparison. The riot camera is used to prevent violence, and the explosion-proof camera is used to explode. The difference between a word and a mile is that the riot camera and the explosion-proof camera are completely different products, which are born according to different environmental needs. In many industries, such as petroleum, chemical, coal, scientific research, military, and research, in the process of experiment, production, processing, transportation and storage, it is often possible to leak and overflow various flammable and explosive. Gas, liquid and various kinds of dust and fiber. When mixed with air, these substances will become a mixture that is prone to explosion hazard. The nearby places will become explosion hazard sites of different degrees, and the concentration of explosive mixture may rise continuously. high. When the concentration of explosives reaches the critical point of the explosion, once the source of the detonation - electric spark, arc and high temperature - will cause serious accidents such as explosions and fires, causing casualties and property losses. In order to achieve application monitoring in a flammable and explosive field environment, explosion-proof cameras have emerged.
The current international mainstream of explosion-proof cameras is flameproof. It is characterized in that a conventional ordinary camera is placed in a special casing, which has the function of isolating the spark and arc generated by the electrical components in the casing from the explosive mixture outside the casing, and can withstand the explosive mixture entering the casing. The explosion pressure generated by the sparks and arcs of electrical equipment, while the outer casing is not damaged, will not cause the explosive mixture outside the shell to burn and explode. This kind of camera with a flameproof enclosure is an "explosion-proof explosion-proof camera", and this special casing is called "explosion-proof enclosure". We usually call it "explosion-proof enclosure". In other words, the explosion-proof explosion-proof camera is the "explosion-proof protective cover" ordinary camera lens. For explosion-proof cameras, the main purpose of explosion-proof is the explosion-proof casing. As long as the size is right, the engineer can freely choose the built-in camera and lens, and the cost is also reduced. For the future maintenance, it is also a lot of convenience, the power can be opened and the camera and lens can be opened. This is also the reason why the explosion-proof camera is currently popular. The explosion-proof enclosure separates the sparks and arcs generated by the electrical components inside the body from the explosive mixture outside the casing, and can withstand the explosive pressure generated by the spark and arc detonation of the explosive mixture entering the casing, while preventing the shell from being exploded. The internal explosives are blasted to the outside world. Therefore, the impact resistance and sealing of the explosion-proof camera housing are much higher than the riot camera.
