WHAT IS IP CAMERA
Pu through monitoring control camera CCTV analog camera: providing an analog signal,
network camera IP Camera = normal surveillance cameras CCTV camera in delhi + network video server
network camera IP Camera fully digital processing technology, the CCD sensor image acquisition, After the analog-to-digital conversion, the digital signal is output. If a CMOS sensor (integrated analog-to-digital conversion and DSP) is used, the digital signal can be directly output, and the subsequent processing and transmission all use digital signals. This fully digital processing method does not need to undergo several conversions between analog and digital, thereby avoiding the image quality loss that may result from multiple conversions. The all-digital interface is adopted to avoid signal interference and transmission distance limitation.
Common monitoring analog camera CCTV analog camera, a CCD sensor of image acquisition. Through the CCD camera for analog-to-digital conversion, image processing (internal DSP), digital-to-analog conversion, and finally output analog signals. The image output by the camera can be used for different applications, such as being connected to the matrix and displaying through video switching; it can also be connected to the DVR for digital storage; it can also be connected to the DVS and compressed for transmission through the IP network.
Analog cameras are relatively mature in technology and very rich in variety, and their applications are quite common. However, if you want to achieve long-distance transmission, you need to resort to other equipment, such as optical transceivers or video servers. The integration of the network camera is high, and it can be directly connected to the IP network to realize the network transmission of the video. For single-point network access, network cameras are more cost-effective than analog cameras + video servers.
