Over the years, people in the pursuit of visual quality never stops. Especially the universal HD concept in recent years, various high-definition products began to appear, especially the display market, such as TV, notebook, monitor, projector and so on, has been fully launched a high-definition battle.
Why to HD monitor era, many users tell the front end must be high-definition video surveillance network camera? Reason mainly in two aspects.
First, HD monitoring must be network, must be based on the video compression and transmission through IP network, because the only way to control the HD video transmission cost. After collection without HD video signal compression analog and digital two transmission modes. Analog transmission generally use the YPbPr component transmission, a high-definition video signal needs three coaxial cable transmission. Digital transmission using DVI, HDMI or HD-SDI transmission, the transmission distance of DVI or HDMI only a few meters, not suitable for monitoring transmission, while the HD-SDI can transmit 100 meters, but on the coaxial cable is very demanding, cable prices are also very expensive. Both the transmission of analog or digital, without HD video signal transmission costs are significantly higher than the previous standard definition video signal simulation. And the use of video compression and transmission through IP network, HD video and marked differences in transmission cost on video is very small.
Second, the direct use of high-definition network camera front-end processing efficiency and cost to more advantage than HD video encoder + HD video camera. The HD video sensor based on CMOS, CMOS sensor is directly output digital video compression coding, directly through DSP or ASIC digital high definition video signal in a video camera, and then to the network transmission, than the camera directly output HD signal is more economical, and higher processing efficiency.
