What is the difference between monitoring the camera and the usual?
Security issues: ordinary USB camera to PC-based Windows operating system, must be inserted on the computer to use. In the security, quality and other aspects of performance significantly, etc., less than monitoring the camera.
Monitoring the installation of the camera, generally need to use a few meters to tens of meters ranging from the transmission distance, but in accordance with the provisions of the USB standard, USB device, the longest transmission distance is 5 meters, so USB can not be used for long distance, that is, we use USB camera to do the first problem encountered monitoring. While the 75-5 / 128 video cable can transmit signals over long distances! (Up to 400 meters).
4.BNC interface: that is, coaxial cable connector. Can cut off the video input signal, so that the interference between the interference reduction, and the signal bandwidth, can achieve the best signal response.
Video capture card: video capture card, also known as data acquisition card and image acquisition card, which is mainly used for security monitoring card, usually on the camera or camera and other signals to capture, and MPEG format stored in the hard disk PCI plug Slot card. Also known as video surveillance card. For more information, please visit: http://baike.baidu /view/3237786.htm
3. Camera effect: monitoring with the camera, generally require high clarity, because the current computer camera commonly used sensor chip is Micron or modern photographic chip, these two kinds of chip camera, clarity are similar, if the use of 5 glass Lens, then the requirements are less stringent occasions are generally able to meet the basic requirements, and 30 frames per second speed is basically able to meet the monitoring needs. If you need better clarity, you can use the physical dynamic 1.3 million camera (not online nonsense 1.3 million, need to emphasize that the sensor chip and interface chip support physical dynamic 1.3 million camera, can really be considered 1.3 million ), This camera is generally better imaging results than the use of magnesium light and modern sensor chip camera, can get better than the average physical 350,000 camera effect, but the bandwidth occupied and CPU occupancy rate is very high. So easy to monitor the camera system easy to use.
