Surveillance Features

Complete Recording Functions

High Quality H.264, MPEG-4, M-JPEG and MxPEG Recordings (depending on the camera models)

All-in-one Recording Functions

  • Continuous/manual/scheduled recording *
  • Alarm recording (by multiple events), alarm recording schedule *
  • Pre-alarm and post-alarm recording
  • Audio recording
  • 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. (Please visit here for camera compatibility list.)
