To put it simply, the array surveillance camera is to combine dozens or even hundreds of lens groups into a lens array, which is similar to the compound eye of insects, so that people can get multiple focuses in the shooting process, with a wider field of vision and a clearer picture.
"Camputer" overcomes the insurmountable contradiction between field of view and resolution in traditional optical imaging technology, and at the same time realizes the ultra-high resolution of large field of view and every detail, which improves the current imaging resolution by two or three orders of magnitude. The breakthrough of this technology plays an important role in the commercial promotion and application of array ultra-high definition cameras.
At present, two ultra-high-definition large-angle array security cameras of Mantis Mantis series can reach hundreds of millions of pixels: one has a field of view of 70 meters and a face recognition range of 70 meters, and the other has a field of view of 150 and a face recognition range of 45 meters.
Ultra-high definition array surveillance cameras can capture details in complex situations. At present, it has been used in Shanghai Pudong Airport, Hongqiao Airport, Guangzhou Baiyun Airport, Xiamen Gao Qi Airport, Yibin High-speed Railway North Station Square, Zhangjiakou "Safe City" and other security fields.
Various types of surveillance cameras
1. Gun camera: Gun camera is one of the surveillance CCD cameras. The bolt is cuboid in appearance, with C and CS lens interfaces in front, and the bolt does not contain lens. The so-called bolt machine is mainly distinguished from the appearance and lens installation interface.
2. Spherical camera: According to the spherical protective cover, it can be divided into spherical camera and hemispherical camera, and according to the installation method, it can be divided into hanging camera, ceiling camera and embedded camera.
3. Hemispherical camera: Because of its small size and beautiful appearance, it is more suitable for office space and places with high decoration grade. Its interior consists of a camera, an automatic aperture manual zoom lens, a spherical cover with excellent sealing performance and a precise camera mounting bracket. Its biggest feature is exquisite design, beautiful appearance and convenient installation.
4. One-piece camera: Today's one-piece camera usually refers to one-piece camera with built-in lens and autofocus.
