Explosion-proof camera harsh environment performance can not be ignored

Nowadays, more and more security cameras have already shouldered the hard work that was once done by humans. For surveillance cameras, in order to meet the needs of people, their technology is also being updated from the inside out. Among the many surveillance cameras, there are one type of cameras that have not been around for a long time, but they often rush into the center of many harsh environments. It is an explosion-proof camera that we often mention. Explosion-proof camera performance is particularly important relative to the working person.

Storm or explosion? The difference between the words is very different

Before we introduce the features of the explosion-proof cameras, we may wish to take the lead to join us to understand the concept of explosion-proof cameras. In the field of cameras, there is a very confusing concept: the difference between explosion and riot. In many people's descriptions, I am afraid that there are explosion-proof and anti-riot mixed experience. So where are the differences between them? Let's talk about the characteristics of riot cameras. In fact, we can see from the literal meaning that the word “violence” refers more to violence or to sabotage. Therefore, the main features of riot cameras naturally begin with the fight and destruction of external forces.

For explosion-proof cameras, although it is also the destruction of external forces, its resistance is obviously stronger than that of riot cameras. Strictly speaking, it is a cross-category product that belongs to a special industry - it can be regarded as a security monitoring product, and at the same time it can be regarded as a tool for tracking and monitoring in the explosion-proof industry. For applications, explosion-proof cameras are more often used for high flammability or explosive field monitoring. For these environments, explosion-proof cameras must have sufficient environmental responsiveness and adaptability. Therefore, only cameras that have been certified by the national authorities as explosion-proof capabilities can be called explosion-proof cameras. Its threshold is naturally more regulated than riot cameras.

Explosion-proof camera selection concerns

Although in our daily life, the demand for explosion-proof cameras may be very far away. But for some specialized special fields, explosion-proof cameras are almost inseparable from their work. How can we start with reference to these cameras?

The comprehensiveness of PTZ work

For high-end surveillance cameras, PTZ has always been an important part of the development of many monitoring devices. Some devices use the characteristics of PTZ to make their own work capabilities have improved by leaps and bounds. In the same way, the decline of other cameras is also constrained by the backwardness of the PTZ, which gradually fades people’s horizons. It can be seen that the PTZ is still very important for the impact of surveillance cameras. The same is true for explosion-proof cameras.

In the application environment of explosion-proof cameras, because most of them are not suitable for the monitoring occasions that the user personally visits, the performance of the pan tilt almost determines the working efficiency of the entire machine. However, for some early explosion-proof cameras, due to technical deficiencies, many devices have the disadvantages of slow speed, poor control accuracy, and obvious blind spots in the monitoring range. Therefore, it also greatly limits the overall performance of the camera.

Motion detection and tracking

In recent years, manufacturers have continued to pay attention to the performance of PTZ. The PTZ performance of the explosion-proof camera has been greatly improved. In terms of rotation speed, high-end products with speeds above 200 degrees per second have been gradually introduced. It can be said that the surveillance camera's flexibility has been upgraded to several levels. And this also made us choose more and enrich our own choice. Of course, due to the fact that the technology span of explosion-proof monitoring products is still very large, the monitoring range is significantly different. Therefore, the performance of PTZ is also the direction we need to focus on.

The motion detection function refers to the detection of the tracking target while it is moving. When the screen changes, for example, if someone walks over, or the sensing device receives an abnormal report, the system will automatically respond accordingly by issuing certain alarm settings. For general surveillance cameras that are primarily used for video scene recording, motion detection and tracking may only be implemented as an enhancement. However, in this flammable and explosive high-risk environment, timely response and reminders become the indispensable working ability of such monitoring equipment.

For the explosion-proof camera's tracking function, it is actually a manifestation of the image analysis function. It depends on the speed of the PTZ, positioning accuracy, etc. If the PTZ of the explosion-proof camera is slow in speed and positioning is not accurate, it cannot be Objects are automatically tracked. This function is usually set through software accessories, background operation control to achieve. Therefore, in addition to the aforementioned PTZ, the performance of the software is also something we must pay attention to.

Alarm self-test function

For the working environment of the explosion-proof surveillance camera, it is often an environment where it is in place, but it is difficult to carry out daily care. Therefore, the self-checking performance of explosion-proof cameras is particularly important. For self-inspection of the equipment, such as being blocked or self-inspected during the PTZ self-checking process, it is difficult for the product to play its practical role. If explosion-proof cameras are used in remote, remote areas where the environment is extreme, winters may face extremely bad weather. PTZ's hinges may be difficult to work due to freezing. Therefore, if the explosion-proof camera does not have a self-check, it may lead to flaws in the entire system. Therefore, the self-test alarm is an important guarantee for the stability of the explosion-proof camera's mechanical performance and smooth operation.

In addition, some explosion-proof cameras also have alarm ports. The alarm interface is connected to other alarm devices. When an abnormal situation is encountered, the alarm linkage function can be realized. If the camera lens of the explosion-proof camera is artificially blocked, it will also call the police to ensure that monitoring can proceed smoothly.

The above are several aspects that need to be focused on when an explosion-proof camera is selected for installation. In addition, in order to enhance the environmental adaptability of explosion-proof cameras, additional value-added accessories such as sun shields, heaters, filters, wipers, and fan/Semiconductor cooling devices are usually added to ensure the stable operation of the equipment and the sharpness of the monitoring screen. . As a unique but very important element of the explosion-proof camera, these can be said to be the lifeblood of the explosion-proof camera. Therefore, this is also a necessary reference direction in our selection process.

The seemingly ordinary explosion-proof camera actually contains so many attention skills. It is also these seemingly insignificant features that ultimately cast the explosion-proof camera extraordinary. Therefore, as long as we grasp these aspects, we will also grasp the future of the use of explosion-proof cameras.
