Get more functionality with the 16 Channel NVR from VIVOTEK

The NR8401 is a 16-channel Linux-embedded NVR from VIVOTEK that offers stable and efficient system operations over a wide range of recording/network management/system settings.

 

But what truly sets the NR8401 apart from other NVRs?

Great surveillance backbone

The unit supports all VIVOTEK camera models, including the latest 5-Megapixel and fisheye cameras.

 

Peace of mind

The NR8401 is equipped with two gigabit Ethernet RJ45 ports which provide network failover/load balance functionality to avoid the risk of recording loss. The front panel provides an easy backup button for users to backup/restore NVR configurations, which is very useful for a rackmount chassis system.

 

Up to 16TB storage capacity and hot swappable

Up to 4 HDDs can be added to the NR8401 for a total storage capacity of up to 16TB (4TB*4). Three removable HDD trays are available in the front of the unit, with hot-swap functionality for easy replacement, and supports RAID 0/1/5 for video data protection and mirroring.

 

Remote management and viewing

A CMS server running VAST software can also directly control the NR8401, and compatibility with the iViewer application allows for remote access to the NR8401 on handheld devices. By integrating all of the components together using VIVOTEK’s NR8401, network cameras, VAST, and iViewer software, users can realize a fully-featured and robust next-generation surveillance system.

 

Other important features include:

  • Embedded Linux
  • 1U Rack Mount Design
  • RAID 0, 1, 5 Storage Solution
  • 4 x HDD Tray, Max. 12TB
  • 2 x Gigabit RJ45 Ethernet Port
  • 3 x USB Port (1 x Front / 2 x Back)
  • 4 x DI / 1 x DO
  • Size: 430 mm (W) x 421 mm (D) x 44 mm (H)

 

VAST central management software

VIVOTEK’s VAST is a highly scalable central management software for video surveillance systems. It supports hundreds of channels in a hierarchical system architecture and offers services including camera control, live monitoring, recording, configurable playback, remote viewing, and alarm handling. As shown in the following picture, VAST can be used to manage NVRs as sub-stations.

 

Applications

The combination of the NR8401 and VAST is an ideal surveillance solution for large security installations consisting of multiple locations connected over a WAN on a single site—such as a company with operations spread over different floors of the same building or in separate buildings or multiple sites connected over the Internet—like a company with separate headquarters, manufacturing facilities, branch offices, and so forth.

 

For such installations, a distributed system architecture offers many advantages. In such an implementation, cameras are clustered on discrete LANs, with an NR8401 recording video from them. Each LAN is in turn connected to the Internet enabling access from a centralized server. VAST runs in this central server, providing the services described above.

 

Example application scenarios

Vivotek 2

A school campus is an example of a site that can greatly benefit from the combination of NR8401 and VAST. The figure below shows a typical university campus, with a variety of indoor and outdoor locations dispersed over a large physical area, each requiring video surveillance.

 

Vivotek 1

 

A conventional centralized system architecture for the university campus—utilizing a central server with unmediated access to all cameras over the campus network—presents a number of issues, including the following:

  • Any network failure would result in the loss of video footage from cameras affected.
  • With so many cameras transmitting video data in real time to the central location, network congestion can be a severe problem.
  • Scalability is poor because additional cameras place increasing bandwidth burdens on the network.
  • Without significant investment in redundant servers, RAID storage and the like, the system lacks fault tolerance, as the central video server represents a single point of failure that can bring down the entire system.

 

A distributed system built around the combination of NR8401 NVRs and VAST, however, provides the school with the following advantages:

  • Live video feeds are accessible everywhere when the campus network is up and are available on individual LANs even when the campus network is down.
  • Offers centralized management through VAST, while avoiding the vulnerabilities of a centralized system architecture discussed above.
  • Allows simpler and less costly video server hardware to be used, since real-time recording can be handled by the NR8401 NVR.
  • Scalability is excellent, as video from additional cameras on existing LANs and even additional groups of cameras can be recorded by an associated NR8401 without adding traffic to the campus network.
