High Speed Dome Camera,someone called it "fast ball", there are people called "integrated dome." But the current market situation of the product is chaotic, high speed dome camera industry has not made particularly clear definition, high-speed dome camera with the speed of the ball, uniform ball, speed ball and so there is no clear distinction between the concept. Even so, the industry generally agree that "fast ball" is "high speed dome camera" for short. Speed Dome Camera and the speed of the ball, as you can shift control, but the speed of the ball speed is 60 ° -120 ° / s; high speed dome cameras speed at 120 ° / s or more; uniform ball can be understood as speed ball or slow speed ball, it can not shift control, constant speed control only in speed at 15 ° / s or less. Divided by the speed high speed dome camera, speed ball, uniform standard ball is currently in the convention industry practice. With the "Green City" construction market heating up, the development of high-speed dome camera is also growing fast, its unique 360 ° rotating function, can monitor all the regional context; easy installation, simplifying cabling and management process; Integration , intelligence and high degree of surveillance has become the darling of the field. Today, high-speed dome camera technology, quality is relatively mature. Whether it is domestic or imported products are priced in adjusted annually, before the majority do not have high-speed dome camera locations such as residential, roads, etc., have begun to increasingly use. Now in a variety of places you can see the figure of high speed dome camera, the application of these areas are to some extent, increased market capacity and speed dome cameras. 

High speed dome camera is a built-in integrated camera,PTZ surveillance system, consisting of a decoder. Optional integrated camera directly affects the image quality speed dome cameras. Decided PTZ control both hardware and software performance factors, the software includes a control circuit, micro-step breakdown and running error correction algorithms, hardware such as motors, housing and so on. Due to the rotation speed dome cameras are up and down and left and right driven by two motors, the motor will directly affect the performance of high-speed dome camera speed, positioning and stability. Thus, by controlling the number of pulses can precisely control the PTZ rotation angle and accurate positioning. On the control of the stepper motor, the vast majority speed dome camera manufacturers are using single-chip microprocessor to control the direction of movement and the number of steps of the stepper motor stepping. With privacy masking, self-learning functions such as track speed dome camera in popularity, it has been difficult to find a single chip to meet the increasingly feature-rich, high-speed dome camera, you must use three or more of the microcontroller as controller, and use dsp as the processor will be the one direction. 

In the initial stage of rapid development Dome camera, people in the purchase of products, mainly considering its normal operating functions, such as focal length range of the camera, pixel horizontal resolution, SNR, shutter adjustment mode, white balance automatically tracking mode, backlight compensation and the ability to automatically switch illumination, etc.; Secondly, PTZ consider horizontal and vertical angles of continuous operation, speed adjustment range, including rapid response capability, reliability and life of high-speed operation, low speed stability of the movement, whether the image dithering and other factors; while the ability to store presets ball machine, the main consideration of the absolute position of the head, the zoom position memory positioning accuracy and so on. However, with the popularity of high-speed dome camera to continuously improve user awareness and people consider the use of a combination of factors such as special occasions, high-speed dome camera features are also continuously updated and improved. As many high-speed dome cameras have increased multi-channel alarm input, telephoto, as the control system automatically learning and other functions. 

Trends in the development of high speed dome cameras, the most important feature of the performance of the function control more intelligent and humane. First, in addition to real-time displays the current time and date, you can also start some timing functions. As in the morning 8:00-9:00 performed automatically set by the first patrol track cruise; 15:00-18:00 pm run auto scan function, more reflects the Dome intelligent features that can meet the more demanding requirements. Automatic tracking function, when an object enters the monitoring range ball machine after a specified target delineation, with the movement of the ball machine can automatically move the target to achieve automatic tracking purposes. Treatment is screened by the parameter accurately in all cases, the call established procedures to determine the ball machine keeps track of target object. Offers a variety of interfaces, in general, high-speed dome cameras now on the market relative to a single interface. Since it is now the industry's rapid development, the relationship between monitoring and it has become increasingly inseparable industry. Many customers at the end of the transmission when using Optical, network or wireless transmission; while the front of the ball machine interface not kept pace with the use of these devices, so a variety of configuration interface will be a trend, including fiber-optic interfaces, network interfaces, and now common interface widely used. In the CCTV system construction, many cameras now on the market in general can be a good solution to monitor the needs of the day, and many manufacturers of cameras have also made substantial progress in reducing the level of resolution and color and so on. However, the ambient illumination becomes very low or no light in the case, in order to comply with the camera to capture the image of the monitoring requirements become more difficult when. If you take the approach enhanced white light illumination to solve, a lot of power consumption will result in the loss of additional resources and costs, while increasing the ambient lighting is not conducive to covert surveillance equipment, even those with malicious intent can remind those who avoid the effective monitoring range. Therefore, the market demand for infrared night vision system is also growing. Relatively speaking, now adding infrared illumination at high speed dome camera is more difficult, but with the development of the market, there will be an infrared speed dome camera constantly appearing on the market. Gradually increased network video surveillance system is being occupied more and more market share, the traditional control method is about to move up and down to control PTZ, but due to network delay, needs a continuous control commands issued to track the target, the search target becomes powerless. If you use direct coordinate control, the space within the scope of monitoring into space coordinates, location coordinates of points required to monitor the location, just send a call to the coordinates command, you can move the center of the screen of the target, which can be accurately find the target object, but also convenient for the user to make the operation more humane. In the open field, when the wind is large, the image on the monitor will sway back and forth. This shaking is due to the rigid pole and bracket attached to the ball machine or other fixed objects inadequacy, shaking amplitude and rigid stent-related. Debounce function relies on the ball machine can be a good solution to this problem, allowing users still can see clear, stable images in windy weather.
