Analog cameras analog cameras with digital network cameras compare analog cameras with digital high-definition network camera comparison? Scan digital high-definition network camera uses progressive scan, each image frame by electron beam sequentially line by line continuous scanning percent. Analog cameras with interlaced interlaced line scanning frequency is half of the progressive scan, interlaced will bring many disadvantages, such as poor interline flicker effect, a parallel phenomenon and vertical edge serrated phenomenon appears effect. The interlaced cause reduce the motion picture clarity. 2 color digital high-definition network camera color can be more realistic than analog cameras. Analog signal transmission process, bright colors can not be completely separated luminance signal doped color signal, resulting in the screen mottled digital network cameras not. Quality color analog camera collection vertical resolution PAL standard under 625 scan lines to 575 lines after blanking, currently up to about 540 lines is the limit, and digital high-definition network cameras of up to more than 800 lines vary considerably far, from the resolution of analog cameras connected as back-end video surveillance equipment, resolution up to 4CIF or D1, about 40 million pixel digital camera can be up to millions or even tens of millions of pixels. 4 wiring analog cameras integrated PTZ control with sound, then the wiring is very complicated, video cable, audio cable, power cord, control lines are independent, large amount of wiring work and the high cost of wiring, and the digital network HD cameras video cable, audio cable, power cord, control line 4-in-1, using a network cable instead of a simple wiring, saves wiring costs. Transmission output and transmission of the analog camera is an analog video signal, it is susceptible to electromagnetic interference. Digital network HD cameras, digital signal transmission, the transmission process without interference troubles.
