Advanced Event Management:

Advanced event management can be divided into two parts:

Events

The VioStor NVR supports different event types, including motion detection, alarm input, connection failure, recording failure, and user-defined event to trigger follow-up actions.

	Motion Detection When the IP camera detects any movement, the defined actions will be activated.
	Alarm Input When the VioStor NVR receives a signal from the IP camera's alarm input, the defined actions will be activated.
	Connection Failure When the VioStor NVR fails to connect to the IP camera, the defined actions will be triggered.
	Recording Failure When the VioStor NVR fails to record video due to hard drive failure or system crash, the defined actions will be triggered.
	User-defined Event* 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.

Actions

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.

	Recording When an event is triggered, the VioStor NVR starts recording one or more channels at the same time.
	Camera Control 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.
	Alarm Output 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**.
	SMS The VioStor NVR sends an SMS message to inform the specified recipients when an event occurs.
	Email When an event occurs, the VioStor NVR sends an email with snapshot to notify the specified recipients.
	Buzzer The buzzer of the VioStor NVR will sound when an event occurs.
	User-defined Action The VioStor NVR supports user-defined actions. Enter the HTTP URL from other surveillance systems. When an alert occurs, the NVR will activate other systems, such as extinguishing system, electronic control system, and air conditioning control system.

* The administrator can enter the following URL in the browser to trigger the event: http://NVR IP/cgi-bin/logical_input.cgi?name=User-defined Event Name ** The VioStor NVR supports the alarm output of AXIS, Panasonic, SONY, ACTi, and VIVOTEK camera models.

Playback Features:
