IP Network cameras in our lives

HD IP Camera image sensor key technical analysis

HD IP Camera usually distinguish between specifications According to the resolution, such as the common megapixels HD IP Camera, which is 1280x720 HD resolution, 1.3 pixels (1280x960), 2 million pixels (1920 × 1080 full HD), 3.2 (2048x1536 pixel) and 5 megapixels, 8 pixels and 10-pixel camera.

In addition, in practical applications, depending on the needs of the environment, the product features a lot of difference, so in addition to the classification and resolution, it is also the basis of their main features, such as WDR camera, low-light cameras, intelligent video analysis of cameras.

An image sensor

HD IP Camera as a camera, must be the key technologies, such as sensors. Sensors, the optical signal is converted into an electrical signal distal end, which is the key technology, the image quality. The sensor in the high-definition network camera, the specific requirements of the application, for example, in order to meet the high-definition image of the data processing capabilities to meet the high-definition large-format images need to be large target surface requires a large amount of the cost pressure and high-definition camera sensor technology challenges .

There are two types: Sensor CCD and CMOS. Generally appear in the analog cameras, CCD, but in the high-definition era, it is difficult. 1080p products, almost all of them use the CMOS. Because most HD cameras using CMOS is very simple CMOS has many cost increase in the absolute advantage of a large number of data processing and CCD HD CMOS technology improved by leaps and bounds in recent years. Early limited number of issues, such as low light and WDR has been resolved. CMOS inherent cost advantage to occupy the mainstream of the field of high-definition network camera.
