4. EVENT SETUP

Event Setup configures detailed options for motion and alarm related recording. It

includes post motion / post alarm recording time, pre-recording option, alarm buzzer,

alarm out, motion grids and their sensitivity levels, and finally alarm input circuit types.

1. RECORD DURATION

Record duration determines the amount of time

the DVR records after the initial motion or alarm

detection. The user may choose from 0, 20, 40,

60, 80, 100, 120, 180 and 240 seconds. Zero

seconds continues to record until the recording is

stopped manually. The default duration is 60

seconds.

2. PRE-RECORD

The DVR keeps at all times 140 fields of

recording in its buffer in order to compensate for

events that happened prior to the initial motion or

alarm detection. When motion or alarm is

triggered, the buffer is divided proportionately

according to the camera number and added in

front of the data when motion or alarm recording

starts.
