Digifort UK explains how its video management software (VMS) and multi-analytics platform works.

The primary recording location is the Digifort VMS servers, which are often centralised. The secondary, recording locations are in either the camaras, usually on SD cards, or in the local hard disc drives (HDDs) of the NVRs. Should there be a network outage that prevents the camera video streams from reaching the VMS server, then self-healing kicks in. Once the network is recovered, the missing camera or NVR video, which has been recorded at the edge, is downloaded to the VMS server, ‘repairing’ the missing time period.

Digifort offers server failover options

Nick Bowden, MD of Digifort UK, said, “Edge recording and self-healing add significant resilience to CCTV systems, with duplicated recording and the ability to repair what is lost. However, within the Digifort VMS, the server itself is significantly more resilient than either cameras or NVRs. RAID5 format for storage HDDs is standard, allowing a damaged drive to be replaced or ‘hot swapped’. Solid-state drives (SSDs) run the server operating system (OS) in RAID1 (mirrored), so if one SSD fails, the spare takes over. For mission-critical applications, requiring even higher levels of protection and continuity, Digifort offers a range server failover options too.

For any Digifort customers wishing to have assistance in designing CCTV systems for resilience, Digifort UK provides system design; optimised server and PC solutions; technical and sales training; pre-deployment services such as configuration and project planning; and site commissioning to support all projects.
