Linux-based networked DVR can record from 64 cameras

Jul 1, 2011 — by Eric Brown — from the LinuxDevices Archive — 22 views

IndigoVision announced a doubling of capacity to 2TB disks on its NVR-AS 3000 of Linux-based, surveillance-oriented network video recorders (NVRs). The NVR-AS 3000 systems are now available with up to 6TB of usable RAID 5 storage, as well as RAID 0/1 options, and can record full framerate video and audio from 64 cameras, and play back 20 streams simultaneously, says the company.

The new NVR-AS 3000 offers twice the storage of earlier models without increasing physical footprint, power consumption, or associated environmental impact, claims IndigoVision. The appliances can be located at any point on the network, without requiring management software or a central server to be running, says the company.

Models are said to be available for rackmount or desktop use in eight different RAID array models with hot-swappable removable drives in capacities ranging from 1TB (RA1000) to 6TB (RA6000). While the four-tray system shown above offers a total capacity of 8TB using 2TB disks, RAID 5 overhead results in a storage capacity of 6TB. Also supporting RAID 5 are the RA1500 (1.5TB) and RA3000 (3TB) RAID array units.

The RA1000, 2TB RA2000, and 4TB RA4000 each provides RAID 1 support, while the latter two appliances are also available in RAID 0 versions, says IndigoVision. The company also sells two fixed disk models without RAID support, available in 1TB (FD1000) or 2TB (FD2000) capacities. The SATA Seagate SV35.5 Series disks on all the units are rated for 24/7 recording and have a three -year warranty, says the company.

All the NVR-AS 3000 appliances can record full framerate video and audio from 64 cameras, and can play back 20 streams simultaneously, claims IndigoVision. Maximum recording bitrate is said to run at 64Mbps except for on the low-end RA1500 and RA3000. All 10 models are said to feature 40Mbps maximum playback bitrate.

The device is said to record both MPEG-4 and H.264 video from multiple cameras "for long periods." For example, with moderate motion levels, a single NVR-AS 3000 can record H.264 video from 32 IndigoVision cameras continuously at 4SIF, full framerate, for over 31 days, claims the company.

By spreading 10 cameras per NVR across more NVR units, one can achieve 90 days of continuous surveillance. The NVRs are said to support third party ONVIF-compatible cameras in addition to IndigoVision's own line of IP cameras.

No processor or memory details were revealed, but the NVR-AS 3000 appliances are said to offer dual, redundant gigabit Ethernet ports. Other features are said to include a suspend/resume button and several LEDs.

All the systems supply fully redundant 100-240V power supplies, says IndigoVision. The RAID array models are said to chew up a maximum of 53 Watts, while the two, fixed-disk models consume 39 Watts.

All the systems are said to measure 19.0 x 10.7 x 3.43 inches (483 x 272 x 87mm). They support 32 to 122 deg. F (0 to 50 deg. C) operating temperatures with the support of cooling fans, says IndigoVision.

An integrated Linux firewall is pre-integrated on the system, and IndigoVision's partially web-based Control Center video management software is said to be available for implementing "advanced redundancy strategies."

The Control Center enables backup NVRs located at any location on the network to continuously record the same video in parallel — called mirroring — to primary NVRs, or else automatically assume recording control if a primary NVR fails. IndigoVision's Security Management Software (SMS 4) is also said to be available.

Availability

The new 2TB-disk versions of the NVR-AS 3000 appear to be available now in usable capacities ranging from 1TB to 6TB, at an undisclosed price. More information may be found at this NVR-AS 3000 page or in this NVR-AS 3000 PDF datasheet.
