What is a key difference between analog and digital CCTV systems?

The key distinction between analog and digital CCTV systems lies in the method of video transmission. Digital systems utilize IP networks to transmit video data, which allows for greater flexibility and scalability. This means that digital CCTV can easily integrate into existing network infrastructures and can support advanced features such as remote access, video analytics, and higher resolutions.

Furthermore, digital CCTV systems can compress video data for efficient storage and transmission. This capability allows for high-definition video quality that surpasses what is typically achievable with traditional analog systems, which transmit video over coaxial cables without the benefits of IP networking.

Analog systems, on the other hand, rely on direct connections through coaxial cables, limiting their functionality compared to digital systems. Hence, while both analog and digital systems have their applications, the use of IP networks in digital systems is a defining characteristic that significantly enhances their performance and capabilities.
