Now most communities, supermarkets and shopping malls are using computers to install monitoring equipment. Now the Shenzhen abosin monitoring installation engineer tells you that there are several ways to install ordinary video monitoring:
1： Ordinary USB camera monitoring can not simply realize remote monitoring in this way. The image can only be seen on the computer equipped with USB camera. It should be civil, so there is not much effort on image compression processing. Therefore, the common problem of monitoring installation is that it occupies a large CPU resource.
2： Monitoring cards are generally used for security. Most monitoring cards are equipped with BNC connectors for coaxial cable connection, not for USB cameras. Generally, software is sent with the card, so that a computer can monitor dozens of images (including video recording), and the CPU occupation is very low (the hard compressed card is lower, and the card is responsible for image decompression).
When you see images, software is attached with you. You can monitor thousands of images and occupy CPU resources. According to the image compression mode of network camera, MPEG4 and H.26 formats are widely used in China. Generally, the current machine configuration can be competent.
During the monitoring installation, the computer or hard disk is usually connected to save the video. However, some people use ordinary USB camera monitoring, install monitoring card or webcam and other methods to adopt the monitoring system, but a serious problem is that the storage time of the monitoring video is very short. Many supermarkets and shopping malls do not pay attention to the data storage of the video, resulting in a large number of monitoring Video data is lost.
