Complete Recording Functions
|High Quality H.264, MPEG-4, M-JPEG and MxPEG Recordings (depending on the camera models)|
|All-in-one Recording Functions
The VioStor NVR supports megapixel recordings (up to 10-megapixel) from various IP 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.

When the VioStor NVR receives a signal from the IP camera's alarm input, the defined actions will be activated.
When the VioStor NVR fails to connect to the IP camera, the defined actions will be triggered.
When the VioStor NVR fails to record video due to hard drive failure or system crash, the defined actions will be triggered.
The VioStor NVR supports user-defined events. The administrator can enter the CGI command in the browser to trigger the event, and the defined actions will be activated.
The NVR supports different actions when an event is triggered. These actions include multi-channel recording, adjusting the PTZ camera to the preset position, alarm output, built-in buzzer, email & SMS alert, and user-defined action.
When an event is triggered, the VioStor NVR starts recording one or more channels at the same time.
When an event occurs, the PTZ camera will be adjusted to the specified preset position for monitoring and recording. Use HTTP URL to activate further actions.
When an event occurs, the alarm output from the IP cameras will trigger other alert systems, such as lighting system, auto phone dialing system, security system and so on**.
The VioStor NVR sends an SMS message to inform the specified recipients when an event occurs.
When an event occurs, the VioStor NVR sends an email with snapshot to notify the specified recipients.
