The intelligent high-speed ball is a type of high-speed ball machine. It has made many improvements in the intelligence and performance of the ball machine on the basis of ordinary high-speed ball machines, and the degree of intelligence and performance have been improved. Compared with ordinary high-speed domes, its performance and intelligence are mainly reflected in the following aspects:
The minimum illuminance of a camera is an indicator that the camera can still obtain a clearly visible picture when the brightness of a subject is reduced to a certain degree. Low-illumination smart domes are generally day and night conversion cameras, low-speed shutter cameras or super-sensitivity cameras. Day and night conversion cameras use black-and-white images to be sensitive to infrared rays. Under certain light conditions, the images can be switched from color to black and white using line switching, and infrared light sources can also be monitored under low light illumination conditions. The low-speed shutter dome camera uses computer memory technology to continuously accumulate several pictures that are blurred due to lack of light and become a clear picture. This type of camera is suitable for surveillance where infrared and ultraviolet light source environments cannot be used and the detected object moves slowly.
The different illuminance environment adaptability, focusing range and image resolution are mainly determined by the performance of the integrated camera inside the dome. The integrated camera is the core part of the high-speed dome camera. Most of these camera cores use the 1/4†CCDs of companies such as Hitachi, Hitachi, Sony, and South Korea’s LG. The camera’s movement and lens determine the high-speed dome. The image resolution of the camera, such as horizontal resolution, focal length, minimum illumination, and signal-to-noise ratio, etc. The resolution is an important indicator of a camera, and it is expressed as the clarity of the image, and the high-definition camera is required to be able to clearly see the pedestrian's facial features. Clearing the license plate number, several common integrated camera resolutions are generally 480 lines, and a few manufacturers have reached 540 lines.
The range of the camera's focal range can be selected for wide-range monitoring, such as 16X, 18X, 22X, and 23X, and individual brands can also achieve 26X and 27X. According to different monitoring ranges, high-speed dome cameras with different focal length ranges can be selected. Different multiples of high-speed ball prices are also very different, so equipment selection must first calculate and then choose a suitable multiple of the ball machine.
Smooth running is an important indicator of the performance of high-speed domes. One of the main reasons why high-speed domes have such a large market is their high-speed rotation capability. Ordinary pan/tilt rotation angles can only be 0~355. °, horizontal rotation speed> 11.2 °/s rotation speed, vertical rotation speed> 4.5 °/s. In general, high-speed domes can achieve 0-360° continuous rotation, 0-90° rotation, and P/T speeds from 0.01°/s to 150°/s, but only smart balls When the machine runs at low speed, there is almost no oscillation and there is no howling at high speed. When the ZOOM is at TELE's maximum state and the low speed operation is reflected on the monitor, the picture is stable and almost no image jitter is noticed, indicating the dynamics of the smart dome. The design and stepper motor subdivision techniques are excellent.
Preset repeat accuracy This is a very important indicator to measure the performance of fastballs. A good smart dome should have a very high preset position accuracy, such as ±0.01°. The significance of defining such a parameter is that when the smart dome camera is at the maximum zoom (TELE), its P/Z repeat positioning accuracy beyond this range may not capture the desired target. This requires the intelligent ball machine to have excellent mechanical design levels and motor motion algorithms. It is difficult to design and manufacture rough products with such high positioning accuracy.
Power adaptability and safety: The smart dome should support AC and DC power supply and support a wide range of voltage input. This requires fast ball power supply designers to master modern power supply design techniques and use highly efficient switching power management chips. Due to the limitations of the overall volume of fastballs, the frequency of switching power supplies must also be increased. Power safety is mainly reflected in that when the internal circuit of the intelligent dome camera fails, it will not affect the power supply line; secondly, when the power supply line fails, the internal circuit of the intelligent dome camera will react quickly, so that such failure will not occur. Damage to the dome camera, lightning protection design of the outdoor smart dome in areas where thunderstorms are frequent.
