With the gradual improvement of people's safety awareness, explosion-proof cameras should be used in more and more fields in theory, but in fact, the usage of explosion-proof cameras is not very large.  What causes this?  The cost of explosion-proof camera is relatively high. The price of an explosion-proof camera is much higher than that of ordinary cameras with the same parameters.  Domestic engineers and users have not yet received these high-priced products with a high degree of acceptance. It still takes time to cultivate and change their consumption concepts and consciousness, which also greatly restricts the popularity of explosion-proof cameras.  The author has learned that in the past two or three years, many manufacturers who used to be ordinary cameras have entered the field of explosion-proof cameras. Most of them have carried out product management according to the mandatory requirements of explosion-proof cameras. However, some of them, under the banner of "explosion-proof", have lowered their product standards without the production and testing capabilities of explosion-proof equipment, thus hitting the market at low cost.  Because some engineering companies or Party A do not know enough about explosion-proof cameras and some manufacturers confuse the concept of publicity, some projects have purchased substandard products, causing serious and even adverse consequences, which are incalculable losses for both explosion-proof camera manufacturers and engineering parties.  According to the cost of explosion-proof cameras, the problem of high price cannot be solved in a short period of time. Although the price of explosion-proof cameras is higher than that of three, the premise is that the product is a product that has passed safety certification. Therefore, it is required that engineers cannot only look at the price when purchasing explosion-proof products, but also purchase fake and inferior security products, bringing potential safety hazards to industrial production.  Explosion-proof camera with insufficient awareness is a special camera developed to realize the application of industrial TV in flammable and explosive field environment.  Explosion-proof cameras are widely used in many fields such as petroleum, chemical industry, coal, scientific research, military and other national industrial enterprises or research departments.  During the processes of experiment, production, processing, transportation and storage, various flammable and explosive gases, liquids, various dust and fibers may often leak and spill out. When mixed with air, these substances will become explosive mixtures, and the places around them will also become explosive hazardous places to varying degrees.  Therefore, it is necessary to use explosion-proof cameras.  If ordinary surveillance cameras are used in these special factories, they will not only fail to protect and monitor, but may also cause explosions and endanger production safety.  Therefore, the existence of explosion-proof cameras is still necessary in those specific factories.  Therefore, explosion-proof equipment manufacturers are required to explain the necessity of installing explosion-proof cameras in special factories when engineers and users ask about the specific conditions of explosion-proof cameras, so as to guide engineers and users to buy suitable explosion-proof products.  Explosion-proof cameras for specific use environments are generally not used in civil monitoring systems, and the general monitoring cameras of civil monitoring systems can meet their requirements. Civil users may not need to install explosion-proof cameras. Explosion-proof cameras are generally used in production sites with relatively special environments, and are now widely used in the country such as petroleum, chemical industry, mines, military industry, medicine, oil depots, ships, drilling platforms, gas stations, fireworks production, grain processing and storage, etc.  This particular environment has largely restricted the wide spread of explosion-proof cameras. In the short term, explosion-proof cameras cannot be widely used in ordinary factories. It needs a process gradually accepted by the public. It is believed that with the continuous improvement of public security awareness, explosion-proof cameras will definitely shine brilliantly in the near future and enter thousands of households.  The surrounding supporting facilities are not explosion-proof enough. A perfect explosion-proof camera, if it is not equipped with explosion-proof back-end equipment or professional construction, it will not give full play to the explosion-proof effect. For example, if it is not an explosion-proof tripod head, or if the transmission wire is exposed, there will be potential safety hazards.  Therefore, engineers are required to consult explosion-proof manufacturers when purchasing explosion-proof cameras, and purchase a complete set of explosion-proof monitoring equipment at the manufacturers. The real meaning is to meet the requirements of explosion-proof, and play the monitoring and explosion-proof role of explosion-proof cameras, instead of causing an explosion accident or explosion when the accident occurs, "adding insult to injury."  Although the above four factors will affect the popularity of explosion-proof cameras in ordinary industries, there is still a large market in some specific production places such as petroleum, chemical industry, mine, military industry, medicine, oil depot, ship, drilling platform, gas station, fireworks production, grain processing, etc.  Under high-risk environment, it is best to adopt explosion-proof products conforming to national standards and shelter explosion-proof cameras, which are widely used in high-risk areas such as petroleum, chemical industry, natural gas and military industry.
