JoAnn Technology: Speed ​​Ball Purchase Concerns

The importance of high-speed ball is self-evident. However, most of the people in the industry and the users who first saw the high-speed ball at the first sight are its zoom factor, illumination index, and rotation speed. This consideration is correct from the big side, but this often overlooks many details and may go into a misunderstanding. For example, some users tend to pay attention to the effect of a test ball machine when they consider purchasing a high-speed dome camera. Several brand ball racks are set up to observe the effect. Often, some high-end dome cameras and low-end dome cameras look like images in temporary vision. There is no big difference, so this method is difficult to distinguish between good and bad.

Because the stability of the dome must be felt after long-term use. In addition, there is no big difference in the appearance of each dome, but it is often distinguished in its internal design and internal components, material selection, and process implementation. Big. In addition, the ball machine's low-speed performance, angular velocity and linear velocity and focal length of the corresponding relationship between the more to measure the inherent quality of the dome.

Some users only care about the speed of high-speed rotation of the dome, but they neglect the low-speed performance of the dome, which requires the user to consider the value of speed in practice. High-speed rotation is to quickly change the dome from one observation angle to another, so high-speed is more for preset positions. For example, when alarm linkage is required, the dome camera needs to quickly go 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 too high a speed for the loss of the motor is very large, low-end ball can achieve this index, but its motor life is very short.

Some international high-end brands of ball machines can achieve this requirement. Everyone should not only stay at high speed, but should pay attention to low speed. For general ball machine tracking and monitoring, the user needs to focus closer to the target to carefully track and observe the target's movement. If the speed is not low enough, the same line speed Caused a lot of angular velocity, the result is that the user can not track, in addition to low-speed tracking to smooth and slow movement, a good ball can do, some low-end ball machine often can not be achieved when a close low-speed tracking The phenomenon of shaking and shaking, so some high-end ball machine can do speed automatically change 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, short focal length is, how much telephoto is. The important function of the high-speed ball In fact, the ball machine should not only stay in the above points, the ball machine is not just a camera, but a complex multi-functional camera system. Manufacturers often add a lot of useful features in it, some users may only consider some basic functions, and some engineers in the installation and debugging in order to save time and do not consider other excellent features, resulting in a functional waste, so that the ball machine Can not fully play its important role. For example, the window shield function of the dome camera is very important.

Nowadays, more and more places are installed on the dome. On the one hand, it is convenient for users to monitor the coverage. On the other hand, some ordinary people’s privacy or some confidential places are exposed on the display screen. Inadvertently, the citizens may infringe upon the citizens. Privacy. Therefore, the manufacturer seriously considered this point in the design process. The window masking function is to mask some important privacy points from observation, so that operators cannot peep privacy and concentrate on important monitoring points. Of course, these are shielded. When an event occurs, it is very likely that the image cannot be obtained. In response to this, some high-end manufacturers use a zoom window shield. When the focal length is too far away to see detailed privacy points, the screening will be automatically cancelled, which ensures both security and privacy.

In the actual selection, the user should also choose different types of domes according to different occasions to match the actual needs. If you need to use a PTZ camera that can be looked at in a sports stadium, you can choose a dome camera with a look-up function to achieve the purpose of looking up from above. The hidden appearance of the elevation camera ensures that the overall design of the venue is coordinated and natural. It and other domes The same powerful function can complete the monitoring task excellently; when it is needed for dustproof and anti-fog applications, we can choose the pressurized ball machine, and its IP67 protection grade can provide higher environmental adaptability; it may be often subjected to man-made destruction. On occasions, we can also choose a vandal-proof ball machine to prevent the destruction of the ball machine due to the destruction of man-made knocking and smashing and ensure the normal operation of the monitoring system.

Selecting the most suitable ball machine according to local conditions can greatly improve the reliability and efficiency of the entire monitoring system.
