Analyze the internal core of the IP HD Speed ​​Dome

At present, with the rapid development of social science and technology, the security market continues to grow, and camera equipment is increasingly pursuing high definition. In the context of high definition, IP high-definition high-speed domes have emerged.

At present, IP high-definition high-speed ball has gradually become the mainstream product in the surveillance market. Next, from the technical point of view, why IP high-speed high-speed ball will become the mainstream product in the market.

The core component - "HD integrated movement"

After years of development, the integrated camera movement has matured its core technology integrated lens design and autofocus algorithm.

The standards for HD-integrated lens quality are broadly divided into: optical performance, stability and consistency of key components. Optical performance mainly refers to the resolution of the lens under various optical multiples, of course, including ghosts, purple fringes, dispersion and other serious problems; key components mainly include components such as aperture, motor and filter switching.

After entering the high-definition era, these technical problems were quickly solved. Different products represented by Japanese lenses, Taiwan lenses and domestic lenses have been formed. Japanese lenses generally have good optical performance and stability, but the price is high; Taiwan lens is relatively cost-effective, but optical performance, especially high-resolution, is not enough; and domestic manufacturers' lens is not very stable and consistent. ideal.

In terms of autofocus algorithms, several major solutions have been formed, such as HD image autofocus solutions represented by TI's DM368, FPGA and ASIC. The solution of FPGA belongs to the realization of hardware circuit, the stability is high, the effect and speed of auto focus are fast; the solution of DM368 belongs to the software system combined with the realization of hardware register, the effect of auto focus is relatively good, but the speed and stability The aspect of sex is yet to be tested; the solution of ASIC belongs to the hardware circuit and simple software implementation, and the stability is high, but the development flexibility of the movement manufacturer is greatly limited, and it is difficult to improve the effect and speed of the auto focus.
