What is the primary difference between analog and digital CCTV systems?

• A. Analog systems use coaxial cables, digital systems use fiber optics
• B. Analog systems provide higher resolutions, digital systems provide standard resolution
• C. Analog systems use coaxial cables and provide standard resolution, digital systems use IP networks and offer higher resolutions
• D. Analog systems are wireless, digital systems are wired

Answer: (C)

The primary difference between analog and digital CCTV systems lies in their respective methods of transmission and the quality of the video they produce. Analog systems typically utilize coaxial cables for transmitting their video signals, which inherently limits the resolution to standard quality. In contrast, digital systems leverage IP networks, which allow for the transmission of higher-quality video. This capability enables digital CCTV systems to capture and display footage in higher resolutions, making them more suitable for detailed monitoring and analysis. The advantage of digital systems extends beyond just resolution; they can also support advanced features such as remote access, video analytics, and integration with other digital security technologies. This overall shift from analog to digital represents a significant evolution in CCTV technology, emphasizing the importance of clarity and flexibility in surveillance applications. Thus, the distinction highlighted in the chosen answer encapsulates the core technological differences between the two types of systems.
