3. 3

4. 4

The correct answer is: 2

The classification of video surveillance technologies typically falls into two main categories: analog and digital. Analog technology refers to traditional systems where video signals are transmitted over coaxial cables. This approach has been widely used for many years and includes the use of technologies like CCTV (Closed-Circuit Television). Digital technology, on the other hand, encompasses modern systems utilizing IP (Internet Protocol) cameras. These cameras transmit data over computer networks, which allows for greater flexibility, higher resolution images, and the integration of additional features such as remote viewing and smart analytics. Both of these categories highlight the evolution within the field of video surveillance, showing how technological advancements have expanded the capabilities and functionalities of security systems. While there are certainly various products and variations within each category, the foundational recognition of these two primary types is essential for understanding the landscape of video surveillance technology.
