16:9 picture quality as defined in the new surveillance HD IP Camera
HD dubbed "title" in this era of rampant "HD", and you could see that in the end what is HD? What is megapixels IP Camera?
Currently, the definition of high-definition appears only in the broadcasting industry, in accordance with the relevant standards, the general aspect ratio of 16:9, at least to resolve the digital signal of 1080i (resolution 1920 × 1080), or the number of scan lines vertical and horizontal direction must meet 720P digital signal, only products meeting or exceeding the above criteria can be classified as high-definition products.
HD IP Camera is greater than 12FPS continuous acquisition the maximum resolution greater than 720P (1280 * 720), and even more than Full HD (1080P 1920 * 1080) to a higher 2048 × 1536 screen Webcams. Meet the definition of high definition above mentioned the HD index number of scan lines vertical and horizontal direction have reached 720P digital signal, can be understood as the HD products megapixels level. Common market 1.3 Megapixel, 2.0 Megapixel Video Network Camera is the so-called high-definition 1.3 million or 2.0 megapixel network camera.
General megapixels IP Camera than traditional analog cameras, network cameras with the following advantages:
1, using the the megapixels level sensor, can get more video information, generally up to 1280 × 1024,1392 × 1024,1628 × 1236 or 2048 × 1536 resolution;
2, images of higher quality, better able to capture the details;
3, progressive scan CCD / CMOS dynamic performance of the screen is more fluid;
4, can support the HDTV widescreen output mode (16:9);
5, wider coverage, the same monitoring area can replace the original multiple fixed point camera and an omnidirectional camera.
IP Camera clarity depends on Sensor performance CCD and CMOS two photosensitive chip CCD sensor in terms of sensitivity, resolution, noise control, high-quality image output, dynamic image performance is better than the COMS, so the vast majority of professional camera still select the CCD as the light-sensitive chip, and millions of HD IP Camera optional Sony ICX series of light-sensitive chip with ultra-low sensitivity illumination, to obtain a clearer image of a camera can not be achieved in a dark environment.
