Why do CCTV images are different from other common cameras?

How do digital CCTV cameras work？?

  • Recently researching CCTV cameras,Who can tell me how do digital CCTV cameras work？

  • Answer:

    Light comes in the lens and hits the imaging chip. The imaging chip - CCD or CMOS - has a bunch of pixels that convert that light into digital information, a series of zeroes and ones. The zeroes and ones are put into IP (internet protocol) data packets that can be used in a computer network. If you want more detail, refer to various areas of wikipedia: digital camera digital video CCD CMOS IP network If this is not enough, then an electronics engineering class should help - there are prerequisites to that.

CCTV installations can also be digital. Digital CCTV often uses Internet Protocol (IP) cameras. An IP camera is a camera that contains the camera and hardware to convert the audio and video signals to a stream of packets that can then be transmitted over a local area network (LAN) wide area network, (WAN) or even over the internet. Digital CCTV has many advantages over analog. First, it can use existing wired or wireless internet, including Wi-Fi. Because of this, it isn't limited by distance. A CCTV camera can be set up in one city and have its signal transmitted easily to another city. Another advantage of digital CCTV is that a series of cameras can be routed to a wireless hub, thus minimizing the amount of cabling required for a complex installation.
