Why Full HD or HD IP Camera are better than Megapixel IP Camera?

    SMPTE defines the Full HD and HD as following:
(1) 1920x1080P / 1280x720P
(2) 25 or 30 frame per second
(3) Resolution needs 16:9
    Now we discuss the different between Full HD/HD and 2M/1.3M/1M IP Cameras. Any IP camera’s effective pixels is more than 1M pixels, we can call that it is Megapixel IP Camera. But there are no any organizations to formula the standard. Many manufactures provide the Megapixel IP Camera, but can’t run as more than 25fps. Many products only provide 15fps or less than it.
    Why we need fit SMPTE’s definition? Everyone knows surveillance field is based on television field. It’s necessary to follow the television trend. In the early, television uses 4:3 resolutions, so surveillance uses 4:3 video. CRT uses interlace system, so surveillance uses interlace CCD sensor. Everything in surveillance follows television’s spec.. Even we know progressive scan is better than interlace scan, we still use interlace system because television use it.
    Right now, television field enter to next country. LCD television will replace the CRT system. LCD can support progressive scan video through D-SUB、DVI and HDMI interfaces. LCD can provide 16:9 panel let audience feel better when they watch TV program. So surveillance’s users don’t need to pay patience to use wrong system. User need 16:9, progressive scan and 30fps video.
