HD-SDI monitoring product outlook analysis

The technical standards for video surveillance are mostly derived from the broadcast domain, and HD-SDI is no exception. In the video surveillance system, the commonly used SDI standard is not HD-SDI (high-definition-digital non-compression technology), and the video data is directly uploaded to a server or a storage device after the digital-to-analog conversion. High-definition digital uncompressed surveillance products based on the HD-SDI standard interface have attracted the attention of security companies due to their high image quality, no delay, and no lossless compression.

As industry insiders say, the core technology of HD-SDI is in the hands of manufacturers such as SDI chip, VideoCodec, and Sensor/ISP. The entry threshold for manufacturers with high-definition network manufacturing capabilities is not high, and the industry is only adopting a wait-and-see attitude. Since 2011, From the end of 2012 to the beginning of the year, the number of users concerned about this series of surveillance cameras surged. When market attention is out of proportion with market applications, HD-SDI may be the main concept card in the middle and low-end markets.

Video surveillance users are mostly industry users, and civilian security is still in the development phase. In other words, HD-SDI has a good market prospect in high-end or special fields such as finance, transportation or government. When network monitoring is not sufficient for high-definition monitoring, HD-SDI can compensate for hardware deficiencies through technology and achieve high-definition analog surveillance. Under the premise of ensuring no-delay transmission, high stability, and high resolution of images, solving the problems of big data storage and long-distance transmission, it is believed that SDI technology will take another step in the future.
