How to choose explosion-proof camera? What points need to be focused on?

Speaking of explosion-proof cameras, many friends may not have heard of them, but there are often explosion-proof cameras in many places in our lives, especially gas stations, docks, factories and warehouses. Some time ago, someone asked Bian Xiao privately, what are the excellent explosion-proof camera brands in China? What points should I pay attention to when choosing an explosion-proof camera? In order to solve these problems of netizens, Bian Xiao will talk about explosion-proof cameras with you today and see how to choose explosion-proof cameras.

What brands of explosion-proof cameras are there?

In recent years, there are more and more explosion-proof camera brands in China, such as buhrer Li in Zhejiang, CLP Equipment in Guangzhou and Hongbo Asia Pacific in Beijing. Of course, there are also many second-tier brands that frequently appear in people's sight in recent years, such as Fangrong Technology in Shenzhen and Shengneng Technology in Xuzhou. Of course, there are many excellent explosion-proof camera brands that have not been mentioned, and friends in need can buy them according to actual needs.

How to choose explosion-proof camera?

1, explosion-proof camera category

The category of explosion-proof cameras mainly depends on our installation location. This is very clear and easy to determine. If you want to install an explosion-proof camera on the wall, you will generally choose a gun-type explosion-proof camera. If installed on the ceiling, generally choose a hemispherical explosion-proof camera. If it is an outdoor environment, pay attention to the IP protection level of explosion-proof cameras. General IP65 explosion-proof camera can meet the outdoor waterproof, dustproof and moisture-proof requirements.

In addition, the bolt machine can also be installed on the ceiling and the hemispherical machine can also be fixed on the wall through suitable mounting brackets. In some broad outdoor monitoring scenes, you can choose an explosion-proof camera with pan-tilt function, which can rotate 360 degrees. The same is true indoors. For example, we can put a small explosion-proof camera on the table in the corner, and turn the camera to see the whole room clearly.

2. Explosion-proof camera explosion-proof type

Explosion-proof cameras can be divided into explosion-proof type, intrinsically safe type and pouring type. Compared with the manufacturing process and later maintenance cost of intrinsically safe and sealed cameras, flameproof cameras are more direct and economical, so the mainstream mode of flameproof cameras in the world is flameproof cameras at present. The working principle of flameproof camera is to use an explosion-proof shell to isolate sparks or arcs generated by electricity in the shell. So even if the outside is full of flammable and explosive gases, it will not cause an explosion. Such a camera can play a monitoring role in flammable and explosive environments, thus ensuring the safety of people. ?

3. Self-checking alarm function of explosion-proof camera

Self-inspection alarm 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. 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. Therefore, the self-checking alarm is an important guarantee for the mechanical stability and smooth operation of explosion-proof cameras. Some explosion-proof cameras also have alarm ports, and the alarm interfaces are connected with other alarm devices. When an abnormal situation occurs, the alarm linkage function can be realized. If the lens of the explosion-proof camera is blocked artificially, it will also give an alarm to ensure the smooth monitoring.

The above three points are the key to choose an explosion-proof camera. Have you learned?
