A video management system, also known as video management software plus a video management server, is a component of a security camera system that in general: Collects video from cameras and other sources; Records / stores that video to a storage device; Provides an interface to both view the live video, and access recorded video
CCTV security cameras can either store the images on a local hard disk drive, an SD card, or in the cloud. Recordings may be retained for a preset amount of time and then automatically archived, overwritten, or deleted, the period being determined by the organisation that generated them.
Such a device is similar in functionality to a PC with a capture card and appropriate video recording software. Unlike PCs, most DVRs designed for CCTV purposes are embedded devices that require less maintenance and simpler setup than a PC-based solution, for a medium to a large number of analogue cameras.
A network video recorder (NVR) is a specialized computer system that records video [1] to a disk drive, USB flash drive, memory card, or other mass storage device. An NVR itself contains no cameras, but connects to them through a network, typically as part of an IP video surveillance system. NVRs typically have embedded operating systems.
For added security centralized storage is frequently used to record alarm video for easy alarm verification and long-term secure storage. Pre-alarm recording is offered by introducing a buffer in the encoder so that the seconds or minutes of video before and after an alarm can be automatically transmitted to the centralized storage.
In the video security industry a video server is a device to which one or more video sources can be attached. Video servers are used to give existing analog systems network connectivity. Video servers are essentially transmission/ telemetry / monitoring devices. Viewing is done using a web browser or in some cases supplied software.
