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.
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.
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
In 2022, Hikvision was awarded a Chinese government contract to develop software to track "key people" in order to prevent them from entering Beijing. [16] [17] The same year, IPVM also reported that Hikvision has specific alarms in its software to alert Chinese police to "religion, Falun Gong, and various protest activities. [18]
In some DVR security systems remote access to security footage using a PC can also be achieved by connecting the DVR to a LAN network or the Internet. Some of the latest professional digital video recorders include video analytics firmware, to enable functionality such as 'virtual tripwire' or even the detection of abandoned objects on the scene.
This software is fully self-learning with no initial programming input by the user or security contractor. In this type of analytics , the A.I. learns what is normal behaviour for people, vehicles, machines, and the environment based on its own observation of patterns of various characteristics such as size, speed, reflectivity, color, grouping ...
Hard disk and other storage drives are subject to failures (see hard disk drive failure) which can be classified into two basic classes: Predictable failures which result from slow processes such as mechanical wear and gradual degradation of storage surfaces. Monitoring can determine when such failures are becoming more likely.
A computer's firmware may be manually updated by a user via a small utility program. In contrast, firmware in mass storage devices (hard-disk drives, optical disc drives, flash memory storage e.g. solid state drive) is less frequently updated, even when flash memory (rather than ROM, EEPROM) storage is used for the firmware.
