How to select different functions of high-definition camera?

2010, millions of high-definition wireless surveillance equipment ushered in the explosive growth in both government projects and civilian control, analog control will gradually replace old ones, as the solution to the problem of network bandwidth, PoE power supply technology maturity, and cost-effective CMOSSENSOR in large field of application security, millions of high-definition will quickly spread.

Million in 2010 ushered in a high-definition monitor explosive growth, regardless of government projects, or civilian control, analog control will gradually replace old ones, as the solution to the problem of network bandwidth, PoE power supply technology maturity, and cost-effective CMOSSENSOR in security large field of applications, millions of high-definition will quickly spread.

    wireless surveillance system are usually divided into two types: one is based on analog cameras into the front-end video and network processing module, analog cameras with the same disadvantages: the image resolution is not high, the highest quality of not more than D1, the other for digital HD network camera, which is characterized by a direct digital video processing and transmission via the network, avoiding the common problem of interference with sensitive analog video camera, the screen can be done clean, crisp and clear picture quality, signal to noise ratio high.

     To megapixels camera can get the best performance, use high-quality megapixels lens will become very important. Optical image quality overall image quality is a key factor, as megapixels network camera 'eye', megapixels camera for the entire image with high contrast, sharpness, and that the sharpness, not megapixels camera can not be fully demonstrated million pixel sensor resolution, especially the edges of the picture.

     CCD and CMOSSENSOR use is based on two-dimensional grid of pixels arranged. These pixels to the optical image is converted into electronic signals. The number of pixels on an image often determines the image resolution, more pixels means higher resolution. Relative to the normal lens, megapixels camera image on the monitor screen shows more detail, showing the details of some good, will not image blur.
