January 3, 2008 -- IndigoVision, a manufacturer of integrated IP video systems, has upgraded its Control Center software and family of network video recorders (NVRs), allowing users to implement advanced redundancy strategies for CCTV recording.
According to the company, the upgrade allows the NVRs to work as failover backups and mirrors for primary NVRs. The backup NVR can continuously record the same video in parallel as the primary NVR (mirroring) or automatically takeover recording if the primary NVR fails. The backup NVRs can be located at a different physical location to the primary NVRs, adding further to the resilience of the system, contends the company.
With the upgrade, the backup NVRs continuously monitor the primary NVRs to check availability and synchronize configurations. The switching of the primary NVR to a backup unit can also be manually initiated to allow routine maintenance or fault investigation of the primary NVR. Several backup NVRs can monitor a single primary NVR and similarly a single backup NVR can monitor several primary NVRs.
Also, sophisticated webs or chains of NVR redundancy can be implemented allowing the user to choose their level of redundancy based on a risk/cost analysis, reports the company. The standalone NVR products also provide a level of built-in resilience with dual redundant network connections and power supplies, RAID configurations, and hot-swappable drives.
In addition to the NVR redundancy features, the latest upgrade to the company's Windows-based Control Center software includes features such as video bookmarks and advanced IRIS control for PTZ cameras. Video bookmarks allow the user to add notes associated with a specific section of recorded video. Like alarms, bookmarks are saved on the NVR and associated with the recording so that other operators can view them.
