is in our daily life, the demand for explosion-proof cameras may still be far away. But for some specialized special fields, explosion-proof cameras are almost inseparable from their work. So how do we start with these cameras? Today, the editor and Mr. Fang from Blairley came to talk with you about the key points of purchasing explosion-proof cameras.

7z, the comprehensiveness of PTZ workFor surveillance cameras, PTZ has always been an important link in the development of many surveillance equipment. Some equipment uses the characteristics of the PTZ to make its own working ability have been improved by leaps and bounds. Similarly, the decline of other cameras is also restricted by the backwardness of the PTZ, which gradually fades out of people's field of vision. It can be seen that the impact of PTZ on surveillance cameras is still very important. The same is true for explosion-proof cameras.
In the application environment of explosion-proof cameras, since most of them are not suitable for users to visit in person, the performance of the PTZ almost determines the working efficiency of the entire machine. However, for some early explosion-proof cameras, due to technical shortcomings, many devices have such deficiencies as slow PTZ speed, low control accuracy, and obvious blind spots in the monitoring range. Therefore, it also greatly limits the more comprehensive performance of the camera.

7z, motion detection and tracking functions
In recent years, as manufacturers continue to pay attention to the performance of PTZ. The PTZ performance of explosion-proof cameras has been greatly improved. In terms of rotation speed, products with a rotation speed of more than 200 degrees per second have been gradually introduced. It can be said that the overall flexibility of surveillance cameras has been improved by several levels. And this also makes us richer in our choices. Of course, since the current technical span of explosion-proof monitoring products is still very large, the monitoring range varies significantly. Therefore, the performance of the gimbal is also the direction we need to focus on. The
motion detection function refers to the detection of the tracking target when it is moving. When there is a change in the screen, such as someone walking by, or when the sensing device receives an abnormal report, through certain settings, the system will automatically make corresponding processing, that is, send an alarm signal. For general surveillance cameras that are mainly used for video scene recording, motion detection and tracking may only be implemented as an enhanced function. But for this kind of flammable and explosive high-risk environment, timely response and reminders have become an indispensable ability for this type of monitoring equipment. For the tracking function of the explosion-proof camera,
is actually a manifestation of the image analysis function. It depends on the speed of the pan/tilt speed, positioning accuracy, etc. An object is automatically tracked. This function is usually set through software accessories and controlled by background operations. Therefore, in addition to the above mentioned PTZ, the performance of the software is also something we must pay attention to.
z67z, alarm self-check function
for the working environment of explosion-proof surveillance cameras, it is often an important place, but it is difficult to carry out daily care in an environment. Therefore, the self-check performance of explosion-proof cameras is particularly important. For the self-inspection of the equipment, for example, if the PTZ is blocked or the self-inspection is not in place during the self-inspection, the product will not be able to play its actual role. For example, if explosion-proof cameras are used in remote and remote areas with extreme environments, they may face extremely harsh weather in winter. The shaft of the gimbal may be difficult to work due to freezing. Therefore, if the explosion-proof camera has no self-check, it may lead to the paralysis of the entire system. Therefore, the self-check alarm is an important guarantee for the stable mechanical performance and smooth operation of the explosion-proof camera.
In addition, some explosion-proof cameras also have an alarm port, which is connected with other alarm devices, and can realize the alarm linkage function when encountering abnormal conditions. If the explosion-proof camera lens is artificially blocked, it will also alarm to ensure smooth monitoring. Above
are the key points that need to be paid attention to when selecting and installing explosion-proof cameras. In addition, in order to enhance the environmental adaptability of explosion-proof cameras, it is usually necessary to add value-added accessories such as sunshades, heaters, filters, wipers, fans/semiconductor refrigeration devices, etc. to ensure the stable operation of the equipment and the clarity of the monitoring picture . As the unique but very important elements of explosion-proof cameras, theseIt can be said that the explosion-proof camera is the lifeblood link of the whole body. Therefore, this is also a necessary reference direction in our selection process.
