Some modern CCTV systems allow for remote access and management, but this requires an internet connection. With an internet connection, the video footage can be transmitted to a remote location, allowing users to view and manage the system from anywhere. However, it’s important to note that this feature is not necessary for a basic CCTV system to function.

To summarize, while remote access and management features may require an internet connection, a CCTV system can still function without one as long as the cameras are connected to a recording device.
