Analog refers to a method of transmitting video signals using continuous electrical waves. In surveillance, analog systems send footage from cameras to recorders through coaxial cables.
For example, traditional CCTV setups rely on analog technology to deliver real-time video without the need for internet connections. These systems are often simple to install and cost-effective for basic monitoring needs.
While analog cameras offer lower resolution than IP cameras, they still perform well in many applications. As a result, some organizations continue to use them in legacy or budget-conscious environments.
By understanding analog systems, users can choose the right technology for their security requirements.
