Which of the following components is crucial for enabling remote viewing of a CCTV system?

A reliable internet connection is essential for enabling remote viewing of a CCTV system. Remote viewing allows users to access their surveillance feeds from locations away from the camera setup, which is typically done over the internet. When the CCTV system is connected to the internet, users can view real-time video footage and access recorded videos through smartphones, tablets, or computers, regardless of their physical location.

In contrast to other components, a high-capacity power supply is more related to ensuring that the system operates without interruptions rather than facilitating remote access. A non-wireless camera system might hinder flexibility and convenience in installation but does not directly impact the ability to view footage remotely. Lastly, while a color monitor is useful for displaying video feed locally, it does not contribute to the remote access capability. Therefore, a reliable internet connection is the key component that enables effective remote viewing of a CCTV system.
