Introducing the "fast" infrared high speed ball

Today's topic is the question of how fast the infrared high-speed ball is. I will follow the author to discuss it.

In real life, due to the use of infrared camera monitoring equipment, we can now see some monitoring equipment in many places. Among them, the infrared high-speed ball has a fast and flexible rotation and a wide range of zoom, so the application field is very broad. The infrared smart ball involves most of the fields including building, transportation, public security, mining, environmental protection, administrative agencies, sports venues, universities, etc. Where 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. In addition, the infrared high-speed dome has a powerful menu function that allows the user to program a menu program that suits the needs. It can be seen that the importance of the infrared high speed ball is self-evident.

However, most people in the industry and the first use of the infrared high-speed ball to see the first thing that comes to mind is its zoom factor, illuminance index, and 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 infrared high-speed ball. 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 fast low-speed performance of the infrared high-speed ball, the angular velocity and the correspondence between the line speed and the focal length are more able to measure the intrinsic quality of the dome.

Some users only care about the fast high-speed rotation speed of the infrared high-speed ball, but ignore the fast low-speed performance of the infrared high-speed ball, which requires the user to consider the value brought by the speed in practice. High-speed rotation is to quickly convert the infrared high-speed ball from one observation angle to another, so the high-speed is more for the preset position. For example, when the alarm is linked, the infrared high-speed ball needs to be quickly transferred according to the alarm signal. The observation area, while the focal length is quickly pulled to a reasonable range, so that users 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.

Summary: Through the above understanding, I hope that everyone has a certain understanding of the development of infrared high-speed ball, and a deeper understanding of the infrared high-speed ball.
