Excellent Hardware Design

Intel 1.6GHz CPU and 1GB DDRII Memory for Superior System Performance
The VS-5020 VioStor NVR is an ideal & powerful network video surveillance system designed for SMB and Enterprise. Powered by Intel 1.6GHz CPU and 1GB DDRII memory, it delivers superior performance for surveillance applications.

Green NVR Solution: Linux Embedded System with Low Power Consumption
The Linux-based NVR is more power-saving and less vulnerable to virus attack compared to PC-based surveillance solution.

Touch-N-Go PC-less Installation by LCD Display
The handy LCD display on the VS-5020 VioStor NVR provides a speedy and easy approach to initialize the NVR and set up the RAID configuration without using any computer. You can use the handy LCD to finish the first time installation in 3 simple steps. The NVR will automatically complete the hard disk formatting and RAID building. When the system is ready, users can check or configure the IP settings, physical disk info, volume info, system info, shut down or reboot the NVR etc.

Ultra-low System Noise, Superior Cooling Design
The low-noise fan of the NVR keeps the hard disks and the system in low temperature for long-term operation. The mesh cover dissipates system heat effectively.

Dual Gigabit LAN Ports for More Deployment Options

Network Failover
Failover allows the VioStor to sustain the failure of one network port to provide continuous services.

Bandwidth aggregation is supported to boost the file transfer speed (works with managed Ethernet switch with 802.3ad configured).

Multi-IP Setting

The VioStor can be deployed with two different IP settings for sharing among different workgroups in two different subnets.

Support 5 High-speed SATA Hard Drives
SATA hard drives are faster than IDE hard drives, which enhance recording and playback performance.

Online RAID Capacity Expansion and Online RAID Level Migration
Online RAID Capacity Expansion
The storage capacity of a RAID configuration can be expanded by replacing the hard drives with larger ones. All the data will be kept and seamlessly moved to the newly installed hard drives. There is no need to turn off the server during the process.



Online RAID Level Migration
Users can upgrade the disk configuration to higher RAID level with the data retained. There is no need to turnoff the server during the process.

S.M.A.R.T. & Advanced HDD Health Scanning (HHS)
The NVR supports Hard Disk Drive S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) for monitoring the hard drive status. The VS-5020 VioStor NVR is embedded with HHS Technology which supports disk checking and bad blocks scanning.
Intelligent automatic system startup when power recovery
The NVR supports intelligent power-on support. When enabled, the system turns on automatically when power resumes after power outage.
