From the lens to the movement, before the domestic movement manufacturers achieved R&D results, most of the movements were controlled by Japanese Sony, Hitachi, Sanyo, and South Korea’s LG, Samsung, and CNB; the shots that accounted for half of the cost of the movement were revived by Nagano, Japan. , Tenglong, Canon and other companies monopolized; CCD, CMOS and other key components have been SONY or other countries such as the United States multinational group monopolized, and high-end autofocus algorithm and high-end night vision fill light and other core technologies in the country is still blank. For the movement, the key technology is in the lens, autofocus, and imaging devices. In the face of such circumstances, many powerful domestic national security companies have persisted in innovating, and have completely independently developed and independently completed the main control board, lens, optical design and production.
Automatic Zoom Lens: In the automatic zoom lens, the world is still based on Japan Dragon, Nagano and Canon as the main manufacturers. In addition, domestic lens manufacturers in Shenzhen have gradually achieved technological breakthroughs through their own design and production. The lens technology of this manufacturer, such as automatic aperture, IR-CUT switching, multilayer coating, aspherical surface, low dispersion, large aperture (aperture value F1.6-F3.2), etc. Full-featured, cost-effective, small-volume zoom lens development and production capabilities.
The domestic optical technology has made great progress. Take a domestic lens manufacturer in Shenzhen as an example. Its optical technology is characterized by its high refractive index, low dispersive material and multiple aspherical lenses, which effectively suppresses the high grade spherical aberration and ensures that The center and peripheral axial and normal directions have high resolution and high contrast at the same time, and the viewing angle reaches 60° to 2.7°.
Photoelectric image processing master control board: At present, the domestic movement program still has not reached a high level of independent R&D and production, and the dependence on foreign major spare parts is still strong. However, domestic manufacturers can develop their own movement plans that meet the requirements of domestic security companies through the selection of different solutions. For example, a domestic movement manufacturer, which mainly adopts SONY and SHARP solutions; in order to meet the needs of different customers and industries, developed three Different kinds of control board solutions: EFFIO-E (economy), EFFIO-S (standard), EFFIO-P (professional).
Megapixel camera lens development and selection
With the popularity of megapixel cameras in recent years, the corresponding demand for megapixel cameras has also grown. In addition to the traditional transportation sector, other emerging industry applications such as city surveillance also ranked HD systems as the first choice. Faced with a wide array of products from security vendors, how do users choose the right lens?
