The High Speed ​​Dome Shopping tips

In real life, due to the ball fast and flexible high-speed rotation, a wide range of zoom, so the applications are very broad, as they relate to areas including buildings, transportation, public security, mining, environmental, executive, sports venues, the vast majority of colleges and universities where the camera needs to be installed. Not only because it can image, but also because it can quickly turn 360 °, allowing users to watch any angle, a different scene from the target, in conjunction with access control, alarm and other systems can also be a good linkage.
Another high speed camera has a strong menu function allows the user needs based on demand for the preparation of a menu program. Thus, the importance of high-speed ball is self-evident. However, most people in the industry and the use of high-speed side saw the ball first thought is its zoom, illumination indicator, rotation speed. This is true from the large surface to consider, but so many of the details often overlooked, and may walk into a misunderstanding. For example, some users consider buying a high speed camera machine, it tends to be concerned about the effect of the test ball machine, ball machine set up multiple brands together to observe the effect, often a number of high-and low-end ball machine ball machine vision appears in the temporary image not much difference, so this is very difficult to distinguish good and bad. Because of the stability ball machine must go through a long-term use can feel it; In addition, the exterior of each ball machine no big distinction, but often inherent in its design and internal components and material selection, process of implementation of the distinction is large. In addition, low speed camera machine performance, speed and angular velocity and the corresponding relationship between focal length and more able to measure the intrinsic quality of the ball machine.
Some users only interested in high-speed rotation of the ball machine speed, but it ignores the low-speed performance of the ball machine, which requires users to consider the speed of operation in practice to bring value. High-speed rotation to the ball quickly from one machine to another observation point of observation angle, so more for high-speed presets, such as the Alarm time, need quick ball machine according to the alarm signal to the observation area at the same time Focus quickly pulled a reasonable range, so that users see the alarm screen time. High-speed technology is not difficult to do, but the high speed of the motor loss is great, low speed camera function to achieve this target, but the motor life is very short, and some international high-end brands of ball machines are also its process performance can meet this requirement. The speed of the ball machine we should not just stop at high speed, more attention should be low, the ball machine for general tracking and monitoring, requires the user to focus closer to the target tracking and observing carefully the target moves, if the speed is not low enough, the same speed caused a great deal of angular velocity, the result is users can not track the other low-speed track to smooth slow movement, good ball function to do some low-end machines often can not do the ball, when the narrow low-speed track will appear flick flick phenomenon, so some functions do high-end ball speed automatically changes with the focal length.
The other is the zoom, some users only care about how many times zoom, while ignoring more range, short-focus is how much, how much telephoto. In fact, the important functions of high speed camera , the ball machine should not just stop at the above points, the ball machine is not just a camera, but a complex multi-camera system. Manufacturers often add a lot of useful features on the inside, some users may consider only some basic functions, and some engineering companies in order to save time in installation and debugging is also not to consider the other outstanding features, resulting in a functional waste, the ball machine can not fully play its importance. For example, a window shielding the ball machine, it is very important. Installation where the ball is now more and more, while convenient for users to monitor the coverage, but on the other while filling some of the ordinary people's privacy, or some secret place exposed to the display, may inadvertently violate a citizen privacy. So manufacturers to seriously consider when designing this point, the window function is to shield the privacy of some important points to observe when the masked, so the operator can not spy on privacy, will focus on the important control point, of course, they are shielded point when an event occurs it is very likely not get the image. On this point, some high-end manufacturers use the zoom window screen, when the focal length zoom for more privacy can not see the point, the shield will be automatically canceled, which not only ensures safety but also to maintain privacy.
In the actual selection, the user should choose according to different occasions, different types of ball machine, to match actual demand. If the stadiums need to look up the PTZ camera, you can choose the ball machine with a look up function to achieve the purpose of looking up the level up, beautiful elevation hidden ball machine venues to ensure coordination of the overall design of nature, it and other ball machine the same power and can monitor the task well done; dust fog occasions in need, we can choose pressurized dome, its IP67 protection rating can provide better environmental adaptability; may often subjected to vandalism in occasions, we can choose to prevent break-ball machine, to prevent man-made knock, hit the ball in damage caused by vandalism, to ensure the normal operation of the monitoring system. Select the most suitable to local conditions of the ball machine, you can greatly improve the reliability of the monitoring system work and efficiency.
