(1) Priority recording is initiated if Priority recording's event occurs.
(2) When the Priority recording ends, recording reverts to Normal

receives a signal or if motion movement is detected.
(4) When the preset Alarm Event recording interval elapses, recording
reverts to Normal recording mode.
(5) Priority recording is initiated if a Priority signal is received or if
manually started during Alarm Event recording.
(6) When the Priority recording ends, recording reverts to Normal
recording.
Notes
• Perform Normal recording settings in auto recording settings.
• Normal recordings are factory-preset to “recordings ON" for all
cameras.
15.4.2. Normal recording
This function automatically records camera images set by schedule. For Normal recording, settable items for
each individual camera include: Recording ON/OFF; Recording Rate; and Picture Quality. (Refer to
p. 81;
Normal Recording setting.) Recordings can be made on scheduled patterns like "day and night," and
"weekdays and holidays” by combining two or more programs.
15.5. Pre-Recording
This function records images immediately before Priority recording or Alarm Event recording is initiated.
Setting the Pre-Recording interval to 1 second or more allows Pre-Recording to be performed. In Pre-
Recording, the recording rate and picture quality cannot be individually set for each camera. Instead,
recording rate, picture quality, and audio ON/OFF settings are common to all connected cameras. The
maximum recording rate per camera is 4 IPS. (Refer to
p. 85; Pre-Recording setting.)
Pre-Recording can be performed under the following conditions.
• When Priority recording begins while recording is stopped.
• When an alarm event occurs and alarm even recording begins while a schedule in which Normal Recording
is not available but Alarm Event Recording is available is in operation.
Note: Pre-Recording cannot be performed during Normal Recording.
