Introduction:
In today's fast-paced world, security is of utmost importance, and surveillance cameras have played a crucial role in ensuring safety for both businesses and homes. As a leading brand in the surveillance device industry, WEILAILIFE has witnessed and contributed to the transformative journey of surveillance cameras. Let's delve into the three generations of surveillance camera systems that have shaped the landscape of security monitoring.

First Generation: Traditional Analog Closed-Circuit Television (CCTV) System
The first generation of surveillance cameras relied on conventional analog closed-circuit television systems. This system included dedicated equipment such as cameras, cables, video recorders, and monitors. Cameras transmitted video signals through specialized coaxial cables, connecting to analog video devices such as video splitters, matrices, switchers, VCRs, and video monitors.

Second Generation: Analog-Digital Video Recording (DVR) System
The second generation introduced the analog-digital video recording system (DVR), which served as a semi-analog and semi-digital solution. The core of this system was the digital hard disk recorder (DVR). Despite the transition to digital recording, the connection between cameras and DVRs still relied on coaxial cables to transmit video signals. The DVR allowed for simultaneous recording and playback and supported limited IP network access. However, the complex wiring requirements remained, with each camera requiring separate video cables, limiting scalability. Typical DVRs could accommodate up to 32 cameras at most.

Third Generation: Complete IP Video Surveillance System (IPVS)
The third generation represents the future of surveillance technology with fully integrated IP video surveillance systems (IPVS). This system significantly differs from the previous generations. IPVS introduces cameras with built-in web servers and direct Ethernet ports. These cameras can generate JPEG or MPEG4 data files, allowing authorized clients to access, monitor, record, and print the footage from any location on the network. Unlike traditional analog systems that generate continuous analog video signal images, IPVS utilizes digital data transmission, enhancing flexibility and scalability.
