IndigoVision, the UK manufacturer of IP video security products, has introduced 2TB disks to its NVR-AS 3000 range of ‘Plug & Go’ Linux network video recorders.
This doubles storage capacity without increasing physical footprint, power consumption or associated environmental control equipment, the firm says. With up to 6TB of usable RAID 5 storage in a single unit, the NVR-AS 3000 is describe as an alternative to Windows-based storage.
The products support fully redundant power supplies and fully redundant Gigabit Ethernet connections as well as options for RAID 0, RAID 1 and RAID 5. Linux means no upgrades or patches as required with Windows storage and its built-in firewall make it secure. Low power consumption and heat dissipation enable units to be rack- or desk-mounted. The company’s distributed architecture means that NVRs can be located at any point on the network, for example near clusters of cameras in order to reduce bandwidth across the network. Backup NVRs can continuously record the same video in parallel to primary NVRs (mirroring) or automatically takeover recording if a primary NVR fails. Backup NVRs can be located at a different physical location to primary NVRs, adding further resilience to physical disruption.
NVRs record full framerate video and audio from 64 cameras and playback 20 streams simultaneously. Models are available with a range of storage capacities from either fixed disks or hot-swappable removable drives. All disks are rated for 24/7 recording and have a three-year warranty. Each NVR can record both MPEG-4 and H.264 video from multiple cameras for long periods. For example, a single NVR-AS 3000 can record H.264 video from 32 IndigoVision cameras continuously at 4SIF, full framerate, based on moderate motion levels for over 31 days. To record for longer periods, spread cameras across more NVRs; for example, for 90 days use 10 cameras per NVR. NVRs record video from both IndigoVision IP cameras and third party ONVIF cameras.
Due to the NVRs’ ultra low power consumption running costs are much lower compared to Windows-based storage. They can be stacked densely in a 19 inch rack, which requires less AC cooling plant and reduces physical footprint.
