DIGITAL VIDEO RECORDER

➄ PRE ALARM TIME LIMIT

The pre-alarm recording is an important function which enables you to find out about the situation

immediately before a motion is detected in the input video or before alarm occurs. Set how much

video data you want to record before the motion is detected or alarm is triggered. About 2 seconds

to 10 seconds of video data are stored in the system’s SDRAM at all times. When a motion is detect-

ed or alarm is triggered, as much data as it is set in the PRE ALARM TIME LIMIT is taken from

the SDRAM and written to the HDD as it simultaneously begins the alarm recording. However, since

the capacity of the SDRAM is limited, the field rate of the pre-alarm recording will decrease as the

time set in the PRE ALARM TIME LIMIT is increased.

[10SECOND/8SECOND/6SECOND/4SECOND/2SECOND/OFF]

➅ POST ALARM TIME LIMIT

Set the amount of video data you want to record immediately after a motion is detected in

the input video or alarm is triggered. The system records as long as the time set in the

MAIN ALARM TIME, and then records more data as long as the time set in the POST

ALARM TIME LIMIT.

[5MINUTE/4MINUTE/3MINUTE/2MINUTE/1MINUTE/30SECOND/20SECOND/

10SECOND/OFF]

➆ MAIN ALARM PICTURE RATE

Set the main alarm recording field rate.

(SCR-3000P models supports recording from 0.50 FPS (Fields Per Second) up to 50 FPS)

● SCR-3000N/SSC-Dual (NTSC)

[60.00FPS/30.00FPS/15.00FPS/10.00FPS/7.50FPS/5.00FPS/2.50FPS/1.00FPS/

0.50FPS]

● SCR-3000P (PAL)

[50.00FPS/25.00FPS/12.50FPS/8.33FPS/6.25FPS/5.00FPS/2.50FPS/1.00FPS/

0.50FPS]

Caution

If the system is currently recording, the PRE ALARM TIME LIMIT settings will not be

applied even when alarm occurs. The PRE ALARM TIME LIMIT settings are applied

only if the system is not currently recording.

Note

The following illustrates the temporal relationship among the main alarm recording

time (MAIN ALARM TIME), pre-alarm recording time (PRE ALARM TIME LIMIT), and

post alarm recording time (POST ALARM TIME LIMIT) based on the time of alarm

occurrence.
