  • 16:9 picture quality define the new high-definition IP surveillance camera

        Dubbed HD "title" product "HD" in this era of rampant, everywhere you can see that in the end what is HD? What is a megapixel IP camera?
        The HD definition only appears in the radio and television industry, in accordance with the relevant standards, generally show a ratio of 16:9, must reach at least be able to resolve the digital signal of 1080i (resolution 1920 × 1080), or the number of scan lines vertical and horizontal direction 720P of the digital signal, only to meet or super to the above criteria can be classified as a high-definition products.
        HD megapixel IP camera is greater than 12FPS continuous acquisition Maximum resolution greater than 720P (1280 * 720), even more than the Full HD (1080P, resolution 1920 * 1080) to a higher 2048 × 1536 screen IP camera. Meet to the HD indicators mentioned above HD definition the number of scan lines vertically and horizontally achieve 720P digital signal requirements, can be understood as high-definition products megapixels levels. Such as the common market 1.3 Megapixel, 2.0 Megapixel IP Camera is the so-called HD 1.3 million or 2.0 megapixel network camera.
        General megapixel IP camera compared to the traditional analog cameras, IP camera with the following advantages:
        1, the megapixels level sensor, you can get more video information, generally up to 1280 × 1024,1392 × 1024,1628 × 1236 or even 2048 × 1536 resolution;
        2, an image display of higher quality, and better able to capture the details;
        3, more fluid dynamic picture performance progressive scan CCD / COMS;
        4, supports HDTV widescreen output mode (16:9);
        5, wider coverage, the same surveillance area can replace the original multiple fixed point camera and an omnidirectional camera.
        The camera´s resolution depends on the Sensor performance compared with the the CMOS two kinds of light-sensitive chip, CCD, CCD sensor sensitivity, resolution, noise control, high-quality image output, dynamic image performance is better than the COMS, so the vast majority of professional The camera still choose CCD as the light-sensitive chip, and megapixel HD IP camera selection Sony the most advanced the ICX series of light-sensitive chip with ultra low sensitivity illumination obtain clearer images in the dark environment, ordinary camera can not be achieved.
