The Qnap VS-2004 Pro VioStor NVR (4-channel, 2-bay) is a centralized network surveillance system, which supports monitoring of IP cameras, video recording, playback and remote data access, and PC-less configuration. It supports real-time 4-channel H.264, MPEG-4, M-JPEG, MxPEG recording from most IP cameras.

With the multi-server monitoring feature, the VioStor NVR allows you to simultaneously monitor up to 120 IP cameras from multiple NVR servers. Based on dual-core Intel Atom processor and with 1 GB memory capacity, the NVR is capable of megapixel recording up to 8MP from multiple IP cameras or video servers.

The VioStor NVR features schedule recording, alarm recording, alarm recording schedule, motion-detection recording, and pre/post-alarm recordings. The digital zoom function of the NVR makes for flexible monitoring and playback. You can adjust the PTZ cameras by the web user interface directly.

Equipped with enhanced video search by IVA (Intelligent Video Analytics), the NVR offers features such as motion detection, foreign object, missing object, out of focus, and camera occlusion. It also offers high security to data by RAID 1, online RAID capacity expansion, online RAID level migration, dual Giga LAN ports for network failover, load-balancing, and multi-IP setting, etc.

The easy-to-install NVR includes features such as event management, convenient backup solution, one-touch audio video backup, security control, E-map, digital zoom, digital watermarking, etc.

The Linux-based network solution (for use in the US) is suitable for small and medium sized companies and SOHO (Small Office/Home Office) such as small stores, restaurants, gas stations, storage yards, and garage.

  • Supports high-quality recording formats - H.264, MPEG-4, M-JPEG, and MxPEG recording
  • Allows scheduled, continuous, or manual recording
  • Events triggered by motion detection or any sensor can be recorded with the alarm recording function while recording schedules can be set for different cameras
  • Megapixel recording up to 8MP from multiple IP cameras or video servers
  • Multi-server monitoring - up to 120 channels from multiple QNAP NVR servers on a remote PC over LAN or WAN
  • Live video monitoring - for live video monitoring
  • Supports different video modes - 1/ 4/ 6/ 8/ 9/ 10/ 12/ 16/ 20/ 25/ 36/ 42-channel and sequential display mode, Picture-in-Picture mode, and multi-display mode
  • Generic IP camera support - using an interface provided by the NVR, you can enter the JPEG CGI command of IP cameras to receive the video and audio streaming data from the IP cameras and monitor, record, and playback the video of the IP cameras on the NVR
  • Smart control of PTZ & speed dome cameras - adjust the PTZ cameras as well as view preset positions of the IP cameras on the local display interface
  • Digital zoom - allows you to zoom in and out video image making for flexible monitoring and playback
  • On-screen event alert - an alert icon is immediately displayed on the local monitoring page in case of event occurrence
  • Videos can be played back on VGA monitor or TV
  • Preset position control - different preset positions of the camera can be viewed, using the number buttons on the monitor page
  • Auto cruising - PTZ cameras can be configured to cruise according to the preset positions and the staying time set for each preset position
  • E-map - allows you to upload the images of monitoring locations for easy preview
Remote Video Playback
  • Multi-view playback - divides a video into multiple sessions equally for playback in a multi-view window as well as you can play videos of multiple IP cameras in the multi-view window simultaneously
  • Easy data search by date & time, timeline, event, intelligent video analytics (IVA) such as motion detection, missing object, foreign object, out of focus, camera occlusion, etc.
  • Enhanced file security by digital watermark - you can ensure file security as the recorded files cannot be tampered with
Event Management
  • Events - motion detection, alarm input, connection failure, recording failure, and user-defined event Actions - video recording, e-mail alert, SMS alert, buzzer, PTZ camera control, alarm output, and user-defined action
  • Real-time SMS and e-mail alert - in case of system error or emergent events, SMS and alert e-mails are sent to the administrator immediately
  • Pre-alarm and post-alarm recording - records additional details before and after an event
Backup Solution
  • Scheduled remote replication - enables you to copy the recording data of the local VioStor to a remote Qnap NAS (Network Attached Storage) on the local network
  • One-Touch-Auto-Video-Backup - allows the recording data to be copied to the USB device immediately
Security Control
  • Authority management - you can create different user groups i.e administrator, system manager, and user and also assign different rights of monitoring, playback, PTZ control, and audio monitoring
  • Auto log-off - allows you to set the timeout period to log off the users when the idling time is over
  • Host access control - you can specify the host or IP connections that are to be allowed and denied to access NVR
  • On-line user list - allows you to view the record of users currently logged on and those that had previously logged on to the NVR
  • Detailed event logs - offers detailed event logs of system warning, hard disk error, network disconnection, UPS status, users' networking services and recordings access record
High Reliability and Smart Features
  • Advanced RAID 1 with hot-swap design - offers advanced RAID 0, 1, single, and supports hot-swap design; a failed drive can be replaced through hot swapping without turning off the server
  • Intelligent automatic system startup after power recovery - the system turns on automatically when power resumes after a power outage
  • S.M.A.R.T. - hard disk status can be monitored with the Hard Disk Drive S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology)
  • Advanced HHS (HDD Health Scanning) supports disk checking and bad blocks scanning
  • DOM Architecture with Embedded Fail-safe Dual OS - the OS and all the applications are embedded on the DOM. Since the NVR allows the system to boot without accessing the physical disk sectors, system startup is not interrupted due to any bad block sectors or file errors on the hard drives; two operating systems offer alternative system booting options upon every system startup - if one fails, the other will be used to boot up instead and the failed OS is recoverable from the other healthy OS
Network Services
  • Dual gigabit LAN ports - available for load balancing, failover, or multi-IP setting
  • Built-in DDNS support - a unique domain name can be registered from a DDNS service provider and assigned to the NVR
  • Built-in NTP server - use the NTP (Network Time Protocol) to synchronize the date and time of the network cameras with the NVR
  • Convenient data access - you can access the recording data on the NVR through the Network Neighborhood (SMB/ CIFS), Web File Management (HTTP), or FTP server
Easy Configuration and Management
  • Power by Intel Atom CPU and 1 GB DDRII memory
  • Smart search of IP camera for quick settings - with the intelligent software utility finder, you can search IP cameras and system settings quickly
  • Up to 4 TB storage capacity for recording long-time video
