Recording Considerations
Timelapse and Event Recording Considerations
Timelapse recording and event recording settings are independent. For example, when an
event triggers an event recording, the system may be set to record at a higher frame rate
and/or at a lower compression rate. An event may be programmed to reset automatically
or it may be programmed to reset only when the operator activates the alarm reset input.
After the event is reset, the normal timelapse recording mode or pre-event recording mode
starts again (see
Timelapse Recording Setup on page 61 and Motion Event Recording
Setup on page 77 , respectively).
During system setup there are two different modes that tell the HRDV16/8 what to do when
the recording space on the disk is full (see
Storage Setup on page 47 ):
• Recycle mode is similar to rewind and re-record for VCR tapes. In this mode the
operator is not warned when old data is being overwritten by new data.
• Stop means that the HRDV16/8 stops recording when the disk is full. In this case the
operator sees a blue screen with a text message on the video monitor with a warning
that the system needs to overwrite old data.
You may use the cursor controls to signal the system to re-record over old data, or to
stop recording to allow you time to archive data to another storage device before it is
lost.
To calculate how much disk space is required for storing timelapse data, see Calculating
Disk Space Required , page 50 .
Event Handling
Any event causes the HRDV16/8 to enter event mode. The HRDV16/8 automatically
detects:
• A full hard drive
• A system error
• Loss of video signal from any enabled camera
• Text, motion, and alarm events as defined in the Event Recording screens (see Motion
Event Recording Setup on page 77 )
The HRDV16/8 can also operate as an event recorder (see Chapter 14, Pre-Event Recording
Setup ).
When an event is triggered, the event recording or event action specified in Program mode
is started.
Examples A Motion event may cause the camera that detected the motion to be recorded at a high
speed and low compression.
When the video signal of an enabled camera is lost, the event may trigger a beeping noise
or a text output to the monitor.
