5.6 IP recording disk space calculation
The following information is useful to calculate the amount of disk space necessary for your installation.
This table is based in one IP camera in movement, recording in continuous mode with different parameters that
may affect the compression and disk space.
As a recommendation, the most important parameter to take into account when calculating the disk space usage
and also the network usage is the Bitrate factor (kbps) that will determine the network bandwidth consumption
and picture quality.
For more information see the chapter hardware requirements.
5.7 NVVR Events and errors
On the following list there is a relation between all the possible events that the NVVR IP recorder can generate.
These events can be seen in the “Events” tab in Nethunter client.
Event message
Type
Description
RecordingStartExternal (REC-01)
Recording event
Information about the rule in the Alarm Matrix that triggered the
recording start.
RecordingStopExternal (REC-02)
Recording event

span expired, or information about the rule in the Alarm Matrix that
triggered the recording stop.
RecordingStartSchedule (REC-03)
Recording event
Information about the Schedule that triggered the recording start.
RecordingStartSchedule (REC-04)
Recording event
Information about the Schedule that triggered the recording stop.
RecordingStartManual (REC-05)
Recording event
RecordingStopManual (REC-06)
Recording event
”Due time expired” if recording stopped because its assigned time
span expired.
RecordingModeChangedExternal (REC-07)
Recording event
IP camera motion detection is triggered
RecordingModeChangedScheduled(REC-08)
Recording event
IP camera motion detection alarm is finished. The alarm duration
depends on the “Motion dwell time” parameter on the camera (2
seconds by default)
RecordingModeChangedManual(REC-09)
Recording event
Camera detected a sensor was activated (optional depending on IP
camera model)
RecordingModeChangedNotRecording (REC-
10)
Recording event
Sensor is disabled.
RecordingHardStop (REC-11)
Recording event
The recorder started recording due to an alarm trigger. The alarm
could be produced by motion detection or by sensor activation.
RecordingFaultRecovered (REC-12)
Recording event
Alarm recording is finished at the specified timestamp. It finishes
immediately when the Motion detection off or Sensor off event is
received.
AlarmOn (ALA-01)
Alarm event
Information about the triggered alarm.
AlarmOff (ALA-02)
Alarm event
Information about the alarm disabled.
AlarmRuleOn (RUL-01)
Rule event
Information about the rule that was triggered on, its alarms, and
actions triggered by it.
AlarnRuleOff (RUL-02)
Rule event
Information about the rule that was triggered , its alarms and
actions triggered by it.
