Network Surveillance, 2Bay

The VS-2108L VioStor NVR is the 2-bay network surveillance system for home and SOHO security applications. The VS-2108L support up to 8TB of storage capacity, with 4TB on each hard drive respectively, to accommodate high quality H.264, MPEG-4, M-JPEG, and MxPEG recording videos.

The unique multi-server monitoring feature of the VioStor NVR allows monitoring of up to 128 IP cameras from multiple QNAP NVR servers at the same time. No extra software is required. Instant alarm icon will be shown and the alarm channel will be highlighted to inform the administrator immediately if an event occurs.

The VioStor NVR supports diversified recording features, such as scheduled recording, alarm recording by multiple alarm events, alarm recording schedule, and pre-alarm and post-alarm recordings. Advanced event management is provided for the administrator to define the handling options when events or alarms are triggered. The VioStor NVR also offers enhanced video search by intelligent video analytics (IVA), such as motion detection, foreign object, missing object, out of focus, and camera occlusion. In addition to managing the VioStor NVR via the web-based administration interface on computers, remote monitoring of IP cameras is also accessible through VMobile app by Android phones, iOS devices, and Windows Mobile phones. The mobile app offers great convenience to monitor connected IP cameras anytime on the go.

All-in-one Recording Functions
- Continuous, manual, and scheduled recordings *
- Alarm recordings (by multiple events), alarm recording schedule *
- Pre-alarm and post-alarm recordings
- Audio recordings
- Auto snapshots
* Different recording schedules for the IP cameras.

Megapixel Recordings
The VioStor NVR supports megapixel recordings (up to 10-megapixel) from various IP cameras.

Multi-stream support
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.

Smart Recording
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.
