Application Comparison: Advantages and Disadvantages of IP and HD-SDI Monitoring
2023-12-09 07:08:57
As we all know, the revolutionary image digital storage technology that was born more than 10 years ago, since then, developers have realized that conversion and compression mean that image quality is reduced. A few years later, IP cameras were developed, including HD IP cameras. However, based on the existing network environment, they still need to follow the conversion and compression technologies of the past, and thus they cannot always meet the requirements of industrial applications.
How to produce a truly high-definition digital video camera without compression and conversion has become the goal pursued by the industry. Therefore, SDI technology derived from broadcast and television technology has gained importance in the field of video surveillance and has been widely used in the past two years.
SDI is a serial digital uncompressed transmission technology. After the analog-to-digital conversion of video, there are two ways to go - compressed or uncompressed. Among them, IP monitoring needs compression, that is, it can compress a large amount of bandwidth, make it possible to transmit video on an IP network, and at the same time reduce the storage pressure of video data, at the cost of sacrificing video quality (generally, there is a loss of information fidelity after compression, even Up to 20% or more), and there is a significant delay, while the openness of the transmission will also bring about certain security risks.
As for the digital non-compression technology indicated by SDI, it is encoded in a special way (lossless digital coding). There are also many technical standards, such as the common HDMI, DVI, and SDI that support 5 Gbps. The advantage is that the video quality is maximally fidelity, and the transmission has almost no delay, but the cost is a huge amount of video signal data.
