Analysis of the development and sensitivity of IP high-definition high-speed ball core

    Due to the fast and flexible rotation and wide range of zoom of high-speed balls, their application areas are very wide, including buildings, transportation, public security, mining, environmental protection, administrative agencies, sports venues, universities and most other places where cameras need to be installed.

    IP high-definition high-speed ball core development

    At present, IP high-definition high-speed balls have gradually become the mainstream products in the surveillance market. With the continuous development of science and technology, the demand for video surveillance has gradually changed from "being able to see" to "seeing clearly". Intelligent ball camera products, as a collection system for video surveillance images, have emerged in the context of high-definition. Next, we will analyze from a technical perspective why IP high-definition high-speed balls have become the mainstream products in the market.

    After years of development, the integrated camera movement has matured in core technologies such as integrated lens design and autofocus algorithm. The quality standards of high-definition integrated lenses are roughly divided into: optical performance, stability and consistency of key components. Optical performance mainly refers to the resolution of the lens under various optical magnifications, and of course also includes the severity of problems such as ghosting, purple fringing, and dispersion; key components mainly include aperture, motor, and filter switching.

    After entering the era of high-definition, all of the above technical problems were quickly solved. At present, different products have been formed, represented by Japanese lenses, Taiwanese lenses and domestic lenses. Japanese lenses generally have good optical performance and stability, but the price is relatively high; Taiwanese lenses have a relatively high cost performance, but the optical performance, especially high-resolution performance, is insufficient; and the stability and consistency of domestic manufacturers' all-in-one lenses are not ideal.

    In terms of autofocus algorithms, several major solutions have been formed, for example, high-definition image autofocus solutions represented by TI's DM368, FPGA and ASIC. The FPGA solution belongs to the hardware circuit implementation method, which has high stability and fast autofocus effect and speed; the DM368 solution belongs to the software system combined with hardware register implementation method, and its autofocus effect is relatively good, but the speed and stability need to be tested; the ASIC solution belongs to the hardware circuit combined with simple software implementation method, which has high stability, but the development flexibility of the movement manufacturer is greatly limited, and it is difficult to improve the autofocus effect and speed.

    Four Questions Analysis on the Sensitivity of IP High-Speed ​​Dome

    How to effectively improve the nighttime effect of IP high-definition high-speed ball to make the night view clearer? How to see farther and more comprehensively while still seeing clearly? How to further reduce the deployment cost of IP high-definition high-speed ball monitoring system? How to meet the industry application needs based on high-definition image quality? In the context of this high-definition era, IP high-definition high-speed ball will continue to evolve and develop through its own technical advantages and characteristics to meet users' various needs for high-definition high-speed ball.

    How to effectively improve the nighttime effect of IP high-definition high-speed dome to make it clearer at night?

    From a technical point of view, the best way to solve the night effect is to use fill light. Whether it is infrared fill light, laser fill light, or white light fill light, it can make up for the night effect of IP high-definition high-speed ball.

    How can we see farther and more comprehensively while still seeing clearly?

    Like the development direction of standard-definition cameras, high-definition integrated cameras with higher magnification will soon be available. In the era of high-definition integrated cameras, the design of lenses with higher magnification will become the focus of technology, as such lenses can solve the problem of seeing farther. However, due to the needs of high-speed ball applications, seeing more comprehensively will also become a direction of technological development. Seeing comprehensively means that when the camera is observing a certain target, it will not lose the monitoring image of the entire scene.

    How to further reduce the deployment cost of IP high-speed ball surveillance system?

    The deployment cost of IP high-definition high-speed ball mainly consists of the transmission system cost, storage system cost and IP high-definition high-speed ball maintenance cost. The reduction of the transmission system and storage system costs will mainly rely on the improvement of the efficiency of the encoding algorithm, such as the H.264 High Profile technology mentioned above. Of course, other methods can also be considered, such as pre-installing the storage (2.5-inch hard disk) in the IP high-definition high-speed ball. The benefits of this are obvious, directly reducing the video's dependence on the IP network transmission system, and at the same time more reasonably allocating the storage system to the user end. For the maintenance cost of IP high-definition high-speed ball, the "0" configuration of equipment deployment and maintenance can be achieved based on the ONVIF protocol, simplifying the operation requirements of construction personnel and reducing the difficulty of system maintenance.

    How to meet the industry application requirements based on high-definition image quality?

    With the advent of the high-definition era, the storage and sorting of massive data will be a great challenge for managers. Users' needs for intelligence will become more and more prominent. The data-structured management of unstructured video data streams will be of great help to managers. The so-called data structuring is to pre-identify the content of concern in the monitoring video through intelligent pre-positioning and organize it into retrievable data. IP high-definition high-speed balls meet the application needs of specific industries by learning and analyzing these data, such as intelligent tracking will be more accurate.
