Create a smart life: the purchase and application of high-speed dome camera

In real life, due to the fast and flexible rotation of the high-speed ball and wide-angle zoom, the application field is very broad, and its fields include buildings, transportation, public security, mining, environmental protection, administrative agencies, sports venues, universities, etc. Where you need to install the camera. This is not only because it can be imaged, but also because it can rotate 360° quickly, so that users can view scene targets of any angle and different distances. At the same time, other systems such as access control and alarm can be well coordinated.

High-speed ball purchase

The high-speed ball has a powerful menu function that allows the user to create a menu program that suits the needs. It can be seen that the importance of the high speed ball is self-evident. However, most people in the industry and the first use of the high-speed ball to see the high-speed ball is the zoom factor, illuminance index, rotation speed. This kind of consideration from the big picture is correct, but this often ignores a lot of details and may go into a misunderstanding. For example, some users tend to pay attention to the effect of testing the ball machine when considering the purchase of a high-speed dome camera. The multiple brand ball racks are set together to observe the effect. Sometimes some high-end ball machines and low-end ball machines look like images in temporary vision. There is not much difference, so this method is difficult to distinguish between good and bad. Because the stability of the ball machine must be felt after long-term use; in addition, there is no big difference in the appearance of each ball machine, but it is often very different in its internal design and internal components and material selection and process implementation. Big. In addition, the low speed performance of the dome, the angular velocity and the correspondence between the linear velocity and the focal length are more able to measure the intrinsic quality of the dome.

Some users only care about the speed of the ball machine's high-speed rotation, but ignore the low-speed performance of the ball machine, which requires the user to consider the value of speed in practical operation. The high-speed rotation is to quickly convert the dome camera from one observation angle to another, so the high speed is more for the preset position. For example, when the alarm is linked, the dome camera needs to quickly transfer to the observation area according to the alarm signal. The focal length is quickly pulled to a reasonable range so that the user can watch the alarm screen in time. High-speed technology is not difficult to achieve, but the speed of the motor is very high. The low-end ball machine can reach this index, but its motor life is very short, and the performance of some international high-end brand ball machines can also be Meet this requirement. Everyone should not only stay at the speed of the ball machine, but also pay attention to the low speed. For the general ball machine tracking and monitoring, the user needs to focus the target closer to the target and carefully observe the movement of the target. If the speed is not low enough, the same line speed. The result is a large angular velocity, the result is that the user can not track, and the low-speed tracking should be smooth and slow moving. A good ball machine can do it. Some low-end ball machines often can't do it. When the low-speed tracking is zoomed in, a one will appear. The phenomenon of shaking, so some high-end ball machines can achieve speed automatically changing with the focal length.

The other is the zoom factor. Some users only care about how many times the zoom, but ignore the comparison range, what is the short focus, and what is the telephoto. The important function of the high-speed ball In fact, the dome should not only stay on the above points, the dome is not just a camera, but a complex and versatile camera system. Manufacturers often add a lot of useful functions in it, some users may only consider some basic functions, and some engineers in the installation and debugging to save trouble and completely do not consider other excellent features, resulting in functional waste, so that the ball machine Can not fully play its importance. For example, the window shielding function of the dome camera is very important. Nowadays, there are more and more places to install the dome. On the one hand, it is convenient for users to monitor the coverage, but on the other hand, it exposes some ordinary people's privacy or some secret places to the display screen, which may inadvertently infringe citizens. Privacy. Therefore, the manufacturer carefully considered this point when designing. The window masking function is to shield some important privacy points from observing, so that the operator can not peep into privacy and concentrate on important monitoring points. Of course, these are blocked. It is very likely that an image cannot be acquired when an event occurs. In response to this, some high-end manufacturers use a zoom window to shield, when the focal distance is too far to see the detailed privacy point, the mask will be automatically canceled, which ensures both security and privacy.

In the actual selection, users should also choose different types of domes according to different occasions to match the actual needs. For example, when you need to use a PTZ camera that can look up in a stadium, you can choose a ball machine with a head-up function to achieve the purpose of looking up horizontally. The hidden beauty of the elevation camera ensures that the overall design of the venue is coordinated naturally, and it is compatible with other domes. The same powerful function can perform the monitoring task excellently; when it is used in dustproof and anti-fog situations, we can choose the pressurized ball machine, and its IP67 protection level can provide higher environmental adaptability; it may be subject to human damage. In the occasion, we can choose the anti-destructive ball machine to prevent the damage of the ball machine caused by the human knocking and smashing behavior, and ensure the normal operation of the monitoring system. Choosing the most suitable ball machine according to local conditions can greatly improve the reliability and efficiency of the entire monitoring system.

High speed ball application

Comprehensive monitoring

At present, high-intelligent high-speed dome cameras are installed on major sections of some cities. Because these cameras have a wide field of view. Therefore, only one position can enable the monitoring personnel to capture the ideal signal, which undoubtedly brings great convenience to the macro management and regulation of traffic conditions. In addition, since most of the high-speed dome cameras currently include a technique of automatically matching the focal length and the rotational speed (autofocus), the spherical camera can provide a stable video effect regardless of whether it is rotated under a large zoom or a small zoom. This also laid an important foundation for the evidence of traffic violations.

Automatic scanning

Due to the numerous and complex roads in many large cities, the road information is changeable. Therefore, this brings great difficulty to the management of road traffic. The intelligent high-speed dome camera can automatically switch between different video points in a fixed area. The user can set the monitoring route and speed according to the requirements and make it run cyclically, so that the camera can ensure its normal operation without being controlled. In this way, the loss of data caused by innocence can be avoided, and the integrity of the road condition data is greatly guaranteed.

Alarm and guidance of high speed dome camera

Automatic alarm

For the traffic violation phenomenon found by the camera, the intelligent high-speed dome camera can respond to the relevant behavior according to the preset settings, and automatically make a response such as snapping or alarming. While dealing with illegal phenomena in the first time, it also reduces the workload of traffic managers.

Road condition monitoring and grooming

At most intersections in Beijing's urban areas, traffic signal control commands are often issued by nearby video surveillance equipment. These devices will judge the smooth condition of the road according to the driving condition of the captured vehicle, and send different commands to the nearby traffic lights according to the road condition information to control the changes of the nearby traffic lights. In order to achieve the most efficient and reasonable road traffic results, the investment in transportation resources is greatly saved. According to statistics, since the use of the intelligent traffic management model, the traffic congestion probability of Beijing roads has been reduced by about 20% compared with before use. This has to make people feel the huge contribution of smart camera equipment to traffic management.

to sum up

In summary, the intelligent high-speed dome camera has gradually become the mainstream equipment in the field of security monitoring with its advantages of high efficiency, intelligence, and clear and stable picture. Its high-speed, high-intelligence working characteristics, wide field of view and diverse installation modes make this kind of camera equipment able to meet the monitoring work in many environments, and thus it is also favored by many special industries. At present, with the development of related science and technology fields, the working ability of high-speed dome cameras is destined to be rapidly improved and improved in line with social needs. It is believed that in the next few years, the intelligent high-speed dome camera will become an indispensable assistant in people's daily life and work, providing more adequate protection for urban security.
