Video surveillance has gone through three stages of development: analog, digital, and network. Before 2000, video surveillance basically consisted of pure analog systems. The system's networking mode was analog video camera + matrix + analog video recorder.

Since 2000, with the maturity of digital video codec and multimedia processing chip technology, digital surveillance systems with video compression cards and embedded hard disk video recorders as the core products have gradually replaced analog surveillance systems as the mainstream of the market. The transition from analog to digital focuses on solving the two core issues faced by video surveillance in the pure analog era: transmission and storage.

With the continuous improvement of network infrastructure and the continuous improvement of network bandwidth and video compression algorithms, video codecs and network cameras have become mainstream network products. Network-based video surveillance systems have begun to be widely promoted in the market and in many industries. And applications, network monitoring is becoming the new trend of video surveillance with its convenient and flexible networking mode and application advantages.

The current high-definition front-end products include two types: one is an HD megapixel digital camera, and the other is an HD megapixel network camera. Due to the lack of high-end digital cameras and high-definition hard disk recorders, the overall cost and engineering application complexity is much higher than that of high-definition network cameras. Therefore, the current high-definition surveillance system is basically based on the application of high-definition network cameras, the market mainly to 720p and 1080p products. The effective resolution of 720p is 1280 x 720 and the effective pixel is 1 million, which is equivalent to 2.5 times that of SD D1. The effective pixel of 1080p is 1920 x 1080, and the effective pixel is up to 2 million, which is equivalent to 5 times that of SD D1.

Because network cameras are highly integrated, easy to use, and easy to maintain, the future high-definition monitoring front-end will be based on high-definition network camera products.

Huanyu Feiyang (Beijing) Digital Technology Co., Ltd.
