Excellent Hardware Design

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

Redundant Power Supply
The VioStor NVR is equipped with two power supply units, each of which is capable of supplying the power for the entire VioStor NVR independently. If one of the units fails, the other one will take over to supply the power to ensure continuous operation of the VioStor NVR. You can replace the failed power supply unit without turning off the server.

Linux Embedded System
The Linux-based NVR is more power-saving and less vulnerable to virus attack compared to PC-based surveillance solution.

Smart Fan
The fan rotation speed is automatically adjusted according to the server's temperature. You can also define the system temperatures to trigger high speed or low speed rotation of the fan.

Dual Gigabit LAN Ports

Failover
The dual LAN ports can be configured as failover which allows the VioStor NVR server to sustain the failure of one network port to provide continuous services.

Load Balancing
The two LAN ports of the VioStor NVR can be configured as load balancing mode for bandwidth aggregation to boost the file transfer speed (works with managed Ethernet switch with 802.3ad configured).

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

Support 4 High-speed SATA Hard Drives
SATA hard drives are faster than IDE hard drives, which enhance recording and playback performance.

Up to 8TB Storage Capacity for Long-term Recording
The VioStor NVR is an excellent choice for long-term recording and saving large amount of recording data.

DOM Architecture with Embedded Fail-safe Dual OS for Enhanced Reliability
All the OS and applications are embedded on the DOM. The VioStor NVR allows system booting without accessing the physical disk sectors and that prevents unsuccessful system startup caused by bad block sectors or file errors on the hard drives. Two operating systems are built on the DOM for system booting alternatively upon every system startup. When one fails, the other one will be used to boot up instead, and the failed OS is recoverable from the other healthy OS.

Lockable HDD Tray
The VioStor NVR provides lockable HDD trays to protect the physical hard drives.

High Reliability and Smart Features

Advanced RAID (1/ 5/ 6) with Hot-swap Design
The VioStor NVR offers advanced RAID 0, 1, 5, 6, 5+spare, single, and JBOD disk configurations. It also supports hot-swap design that a failed drive can be replaced by hot swapping without turning off the server. Besides, the best-in-class RAID on the VioStor NVR brings users a higher level of data security by allowing one more hard drive failure than other NVR of the same level.

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 VioStor NVR supports Hard Disk Drive S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) for monitoring the hard drive status. The VioStor NVR is embedded with HHS Technology which supports disk checking and bad blocks scanning.

Intelligent Automatic System Startup when Power Recovery
The VioStor NVR supports intelligent power-on support. When enabled, the system turns on automatically when power resumes after power outage.

Support UPS System for 24x7 Service
The VioStor NVR supports both APC and MGE UPS devices to enable stable and continuous recording 24x7. With UPS, the system can function normally in case of power outage or unstable power supply.

Powerful Security Control and Network Services

Powerful Authority Management
To improve the security of the VioStor NVR, the user access control feature is strengthened. The users can be assigned to different user groups (administrator/ system manager/ user). Different rights of monitoring, playback, PTZ control and audio monitoring can be assigned to individual user.

Powerful Host Access Control
The administrator can specify the connections to be allowed and denied to access VioStor NVR.

Auto logoff
QNAP NVR supports automatic user logoff from idling configuration pages. The administrator can set the timeout period to log off the users when the idling time has reached in order to enhance secure management of the NVR.

Provide On-line User List
You can view the record of users currently logged on and previously logged on to the VioStor NVR.
