All-in-One Recording Functions
Alarm recording (by multiple events), alarm recording schedule
Pre-alarm and post-alarm recording
Different recording schedules for the IP cameras
Supports megapixel recordings (up to 10 Mp) from various IP cameras
Administrators now can flexibly define multiple video streams on 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.
Real-time Digital Watermarking
Supports real-time digital watermarking to protect the videos and snapshots from unauthorized modifications. The Watermark Proof utility is provided to verify whether or not the videos and snapshots are original.
