Analysis million core technology of HD IP Camera
HD IP Camera usually its resolution is the number of pixels to the different, but with different specifications and classifications, such as is often said that the megapixels HD IP Camera, 1280x720 HD resolution, 1.3 megapixel (1280x960), 200 million pixels Full HD (1920x1080), 3.2 megapixel (2048x1536) and beyond 500 million or 800 million, 10 million pixel camera.
In addition, in practical applications, depending on the needs of the environment, product characteristics also have different requirements, so in addition to many mega pixels exceptionally, in accordance with the classification of the other main features, if applicable, in the light and dark different scene wide dynamic camera, suitable for low-light cameras in low-light environments, intelligent video analytics cameras, etc. for special high-risk active early warning surveillance applications.
An image sensor
HD IP Camera as a camera, you must have a surveillance camera has key technology areas, such as sensors (Sensor technology). Sensor link as the most distal end of the optical signal is converted into an electrical signal, the key technology is most directly affect the image quality of the camera. HD Network Camera, this is no exception, and the sensor has applications in high-definition IP Camera on the specific requirements need to be able to meet the high-definition image uptake required a large amount of data processing capabilities, as well as required to meet the high-definition large-format image large the target surface, which gave the HD IP Camera sensor technology, which brings the cost pressures and technical challenges.
Video compression algorithm
Another key technical aspects of the HD IP Camera is the video compression algorithm, video images transmitted by the network after digital compression This is the most basic functions of the Network Camera, video compression algorithm is better than the poor directly determines the quality of the video image. Can be viewed from two perspectives, on the one hand, a good video compression algorithm, you can minimize the distortion of the picture, it is well known video compression are lossy compression used in network transmission, information on the screen is bound to lose, so necessary maximum in the case of compression ratio to meet the retained most of the information on the screen; case the other hand, video compression algorithm, and can provide a better picture of the effect, using a lower bitrate means occupy more low bandwidth and less storage space.
