Which component is essential for remote viewing in CCTV systems?

The essential component for remote viewing in CCTV systems is video management software (VMS). This software facilitates the management and analysis of video feeds from the CCTV cameras, allowing users to access and control video streams from remote locations through the internet or a local network. VMS typically includes features like live viewing, playback of recorded footage, and advanced functionalities such as motion detection, alarm notifications, and multiple camera viewing.

While other components like a digital video recorder (DVR) play an important role in storing video footage, they do not inherently provide the capability for remote viewing unless paired with VMS or similar software. A high-resolution monitor is beneficial for displaying video clearly but does not contribute to the remote access aspect. Closed-circuit cables are necessary for connecting cameras to the recording device or network but do not facilitate remote viewing on their own. Thus, VMS stands out as vital for enabling users to monitor their CCTV systems from distant locations.
