The VS-2004L VioStor NVR is the 2-bay network surveillance system for home and SOHO security applications.
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. Moreover, you can use the video surveillance application "VMobile" to monitor the IP cameras with your iPad, iPhone, iPod touch, and Windows PDA phones anytime, anywhere.

Complete Recording Functions:
High Quality H.264, MPEG-4, and M-JPEG Recording (depending on the camera models)
All-in-one Recording Functions:
Alarm recording (by multiple events), alarm recording schedule*
Pre-alarm and post-alarm recording
* You can set different recording schedules for different 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.
