Convenient Backup Solution

Storage Expansion
The storage capacity of the VioStor NVR can be expanded by connecting to multiple QNAP Turbo NAS servers.

	Scheduled Remote Replication The VioStor NVR supports scheduled remote replication for secure recording backup to a remote NAS on LAN.
	Video Backup to External USB Storage Configure and press the one touch auto video backup button to copy the recording data instantly from the NVR to an external storage device via the front USB interface.

Security Control

	Authority Management The administrator can create multiple users on the VioStor NVR and assign them to different user groups (administrator, system manager, or user) with different rights of monitoring, playback, PTZ control, and audio monitoring.
	Auto Logoff The VioStor 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.
	Host Access Control Specify the host or IP connections to be allowed and denied to access the NVR.
	On-line User List View the record of users currently logged on and previously logged on to the NVR.
	Detailed Event Logs The VioStor NVR provides detailed event logs of system warning, hard disk error, network disconnection, UPS status, and access to the networking services of the NVR and video recordings.

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 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 NVR 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) Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) helps the administrator monitor the hard disk drives status. The VioStor NVR supports Hard Drive Health Scan (HHS) 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.

Network Services

	Dual Gigabit LAN Ports Failover The LAN ports of the VioStor NVR can be configured in failover mode which allows the NVR to sustain the failure of one network interface and provide continuous services. Load Balancing The LAN ports of the VioStor NVR can be configured in load balancing mode for bandwidth aggregation to boost file transfer speeds. It works with managed Ethernet switch with 802.3ad configured. Multi-IP Settings  Two IP settings can be configured on the NVR to allow network access from two different subnets.
	Built-in DDNS Service The VioStor NVR supports dynamic DNS (DDNS) for convenient access to the system via a domain name instead of a lengthy IP address.
	Built-in NTP Server This feature allows the connected IP cameras to synchronize their date and time settings with the NVR.
	Convenient Data Access The video data on the VioStor NVR can be accessed by the following protocols with proper access rights: SMB/CIFS (Windows) HTTP (Web file management) FTP

Easy Configuration and Management

System Setup in Simple Steps
The NVR can be set up in 6 simple steps by the local display or web-based interface (Internet Explorer).

Web-based User Interface
All system configurations, monitoring, and playback features of the NVR can be managed by the web-based interface.

Smart Search of IP Cameras for Quick Settings

Huge Storage Capacity for Long-term Recording
The VioStor NVR supports up to 24TB of physical storage capacity (3TB hard drive x 8) for recording large amount of video data in a long period of time.

Advanced Event Management:

Advanced event management can be divided into two parts:

Events

The VioStor NVR supports different event types, including motion detection, alarm input, connection failure, recording failure, and user-defined event to trigger follow-up actions.

	Motion Detection When the IP camera detects any movement, the defined actions will be activated.
	Alarm Input When the VioStor NVR receives a signal from the IP camera's alarm input, the defined actions will be activated.
	Connection Failure When the VioStor NVR fails to connect to the IP camera, the defined actions will be triggered.
	Recording Failure When the VioStor NVR fails to record video due to hard drive failure or system crash, the defined actions will be triggered.
	User-defined Event* The VioStor NVR supports user-defined events. The administrator can enter the CGI command in the browser to trigger the event, and the defined actions will be activated.

Actions

The NVR supports different actions when an event is triggered. These actions include multi-channel recording, adjusting the PTZ camera to the preset position, alarm output, built-in buzzer, email & SMS alert, and user-defined action.

	Recording When an event is triggered, the VioStor NVR starts recording one or more channels at the same time.
	Camera Control When an event occurs, the PTZ camera will be adjusted to the specified preset position for monitoring and recording. Use HTTP URL to activate further actions.
	Alarm Output When an event occurs, the alarm output from the IP cameras will trigger other alert systems, such as lighting system, auto phone dialing system, security system and so on**.
	SMS The VioStor NVR sends an SMS message to inform the specified recipients when an event occurs.
	Email When an event occurs, the VioStor NVR sends an email with snapshot to notify the specified recipients.
	Buzzer The buzzer of the VioStor NVR will sound when an event occurs.
	User-defined Action The VioStor NVR supports user-defined actions. Enter the HTTP URL from other surveillance systems. When an alert occurs, the NVR will activate other systems, such as extinguishing system, electronic control system, and air conditioning control system.

* The administrator can enter the following URL in the browser to trigger the event: http://NVR IP/cgi-bin/logical_input.cgi?name=User-defined Event Name ** The VioStor NVR supports the alarm output of AXIS, Panasonic, SONY, ACTi, and VIVOTEK camera models.

Playback Features:

Multi-view Playback
Use the multi-view playback feature to divide a video equally into multiple sessions for playback in a multi-view window, or play the videos of multiple IP cameras in the multi-view window simultaneously.

Real-time Digital Watermarking The VioStor NVR supports digital watermarking to protect the videos from unauthorized modification.
Data Search by Date & Time, Timeline, Event, and Intelligent Video Analytics (IVA) The VioStor NVR supports quick search of recording data by date and time, timeline, event, and intelligent video analytics (IVA), including motion detection, foreign object, missing object, out of focus, and camera occlusion.

Motion Detection: Detects movement in the video. The moving objects of the search area are highlighted in red brackets.
Foreign Object: Detects a new object in the video. The foreign objects of the search area are highlighted in yellow brackets.
Missing Object: Detects a missing object in the video. The missing objects of the search area are highlighted in yellow brackets.
Out of Focus: Detects if the IP camera is out of focus.
Camera Occlusion: Detects if the IP camera is obstructed.
