The VioStor NVR supports megapixel recording (up to 10-megapixel) from various IP cameras.
Administrators now can flexibly define multiple video streams (supported by specific camera models) according to bandwidth resources and number of live-view channels. The adjustable video stream setting helps improve the displaying quality of live-view and well manage the bandwidth resources based on different usage requirements.
The VioStor NVR automatically selects video streams from IP cameras for different recording scenarios. In normal situation, video recording maintains at lower quality resolution. While the alarm event happens, video recording switches to high quality resolution to capture more details. In other words, smart recording effectively avoids the constant storage consumption at all time, but achieves greater storage efficiency and boost recording quality when alarm events happen.

High Reliability and Smart Features
Advanced RAID with Hot-swap Design
The VioStor NVR supports RAID 0, 1, 5, 6, 5+hot spare, 6+hot spare, single, and JBOD disk configurations. Its hot-swap design allows a failed drive of a disk volume, RAID 1 or above, to be replaced by hot swapping without turning off the server.
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
Upgrade the disk configuration to higher RAID level with the data retained without turning off the server.
S.M.A.R.T. & Advanced HDD Health Scanning (HHS)
S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) helps monitor the hard disk drives status. The VioStor NVR supports HHS (HDD Health Scan) for disk checking and bad blocks scanning.
Automatic System Startup after Power Recovery
The VioStor NVR supports automatic system startup after a power recovery.
UPS Support for 24/7 Service
The VioStor NVR supports APC, CyberPower, MGE, and YEC UPS devices to provide continuous services 24/7 against unexpected power outage.
DOM Architecture with Embedded Fail-safe Dual OS for Enhanced Reliability
All the OS and applications of the VioStor NVR are embedded on the DOM. The VioStor NVR allows system booting without accessing the physical disk sectors which prevents unsuccessful system startup caused by bad blocks 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 for system startup and the failed OS is recoverable from the other healthy OS.
Dual Gigabit LAN Ports
This mode allows the VioStor NVR to sustain the failure of one network portto provide continuous services.
