History of the development of video surveillance camera technology

First era: Analog video surveillance camera era.
This era mainly began in the 1970s, when video surveillance camera equipment became the main equipment. The transmission method mainly used coaxial cable, and the transmission and control were analog, and the recording and storage medium was mainly VCR. However, due to the limited tape capacity of VCR, it was necessary to frequently replace the VCR tape in order to achieve long-term recording. In the analog video surveillance camera era, due to the constraints of the storage capacity of VCR, problems such as low automation efficiency and slow recording search were left unsolved.

Second era: Semi-digital video surveillance camera era.
This era mainly began in the 1990s. Hard disk video recorders (DVRs) were the core equipment of the semi-digital video surveillance camera era. DVRs are the main products of this era, and by digitally encoding and storing analog video signals, they effectively solved the problems of low automation efficiency, slow search and other issues left behind in the analog era, and replaced VCRs.

Third era: The era of fully digital (networked) video surveillance cameras.
The era of fully digital video surveillance cameras is the current era of smart network video surveillance cameras, and the system has characteristics such as openness and distribution, so there is no core hardware equipment in this era. OOSSXX's home wireless solar-powered, battery-powered and POE-powered security cameras adopt the next-generation advanced H.265+ video compression standard to save capacity, and can record for more than twice as long as traditional H.264 while maintaining image quality. When the HDD is full, the previous data is automatically overwritten. 5 million high-definition camera, improved heat dissipation and durability, and four times longer service life. Remote monitoring can also be performed by connecting with a smartphone through the network to download and back up the recorded data. Video encoders, network cameras, and central management platforms are the main equipment in the era of fully digital video surveillance cameras. In this era, video content analysis technology is mainly used to realize functions such as storage, playback, and transmission of network videos, and is effectively used with functions such as dispatch, command, and control of video surveillance camera systems. OOSSXX strives to provide advanced technologies and solutions in the era of fully digital video surveillance cameras to meet the demands of our customers.
