Comparison Of The Advantages Of SDI Cameras And IP Network Cameras

In recent years, with the continuous rapid development of IP HD, SDI cameras have also attracted the attention of many friends in the surveillance industry. SDI camera is a product specifically oriented to the high-end security market based on the current situation of the high-definition camera market. It adopts HD-SDI interface to facilitate matching with its back-end codec and video server, and can be directly projected to the control center with the high-definition video matrix The large screen makes the entire high-definition system no longer as complicated and difficult to operate as the IP network system, and it is easier to be a product accepted by traditional security engineering companies. So what are the advantages of SDI cameras and IP network cameras that can be compared?

Communication interface: The difference between the two is obvious from the communication interface. HD-SDI cameras use SDI interface and RS-485/232, LAN; IP network cameras use adaptive Ethernet ports, RS-485/232 and WIFI. From this we can also see that there will be a certain difference in the application areas of the two.

Output video resolution: SDI cameras and IP network cameras can both output 720P and 1080P high-definition video, while cameras with sdi interface can play a key role when upgrading 4K ultra-high-definition video in the future. Therefore, HD-SDI cameras will have more Good scalability.

Image quality: In the process of transmitting video signals, IP network cameras need to compress the video and there will be a certain delay in transmission, while HD-SDI cameras will not.

Signal transmission: SDI cameras also have advantages. Both the transmission distance and the transmission rate are higher than IP network cameras. This is better than IP network cameras in some professional and demanding applications.

The advantages of SDI cameras and IP network cameras will be shared here. Both SDI cameras and IP network cameras have room for promotion. In the future, we may be able to combine the advantages of the two to develop a camera that is more convenient for our remote video monitoring. .
